Percutaneous femoral artery closure devices are being used routinely after cardiac catheterizations. The use of these devices has been advocated to decrease length of stay, promote early ambulation, and prevent bleeding. We reviewed the use of these devices in our institution and report three cases of infectious complications (two pseudoaneurysms and one infected hematoma). Reports of infected pseudoaneurysms after cardiac catheterization before the implementation of these devices are rare. The use of these devices may be associated with an increased incidence of infected femoral pseudo-aneurysms.  相似文献

As the number of cardiac and interventional radiologic procedures has risen, the frequency with which surgeons are called to treat groin complications has increased. Infectious groin problems that often involve foreign prosthetic material or remnants of percutaneous femoral closure devices are particularly challenging and require control of bleeding, removal of foreign material, wide debridement, and sometimes arterial resection. Management of the consequential limb ischemia in such cases is controversial. The purpose of this study is to review the utility of extra-anatomic common femoral bypass through the obturator foramen (obturator bypass) as a method of treating limb ischemia after arterial groin infection. From July 1992 through June 2001 a total of 12 patients (six male) presented with severe vascular infections of the groin and underwent obturator bypass. Infections occurred as a consequence of an isolated vascular graft infection (nine) or after a percutaneous interventional femoral access procedure (three). Patients presented with systemic sepsis and a draining sinus (six), infected pseudoaneurysm (two), or hemorrhage (four). Treatment included debridement of the groin wound, sartorius muscle flap coverage of the femoral vessels, antibiotics and synthetic (eight polytetrafluoroethylene and four Dacron) obturator bypass via a lower abdominal extraperitoneal incision from an aortobifemoral bypass graft limb to the superficial femoral artery (six), native iliac to femoral artery (three), iliac to popliteal artery (two), and aortobifemoral bypass limb to the popliteal artery (one). Graft patency and limb salvage were assessed by Kaplan-Meier life table analysis. There were two (17%) deaths (multisystem organ failure at postoperative days 9 and 6) and four major complications (25%) requiring reoperation in the first 30 days. Ten patients (83%) survived, healed their groin wounds, and are infection free. With a mean follow-up of 37 months graft patency and limb salvage at 60 months were 80 and 60 per cent, respectively. There were no late graft infections. We conclude that the obturator bypass is an effective and durable means of revascularization in the presence of the septic groin. This procedure belongs in the armamentarium of all surgeons managing these complications.  相似文献

BACKGROUND: Femoral access site complications have increased as the fields of invasive cardiology, radiology, and endovascular surgery have emerged. In order to address one of these complications, hemorrhage, the hemostatic puncture closure devices were developed. METHODS: Retrospective review of cardiac catheterizations performed at a single institution to investigate infectious groin complications related to use of the Perclose Prostar and Techstar devices. RESULTS: Infectious groin complications were significantly higher in the Perclose group as compared with manual compression. Three patients had clinical and laboratory evidence of arterial infection whereas 2 had soft tissue infections. All 5 required operative intervention ranging from incision and drainage to arterial reconstruction. Hemorrhagic complications were not significantly different between the two groups. CONCLUSIONS: The Perclose devices provide hemostasis after femoral artery catheterization similar to manual compression. However, infectious groin complications appear to be more common with these devices.  相似文献

Groin wound infections following vascular reconstructive surgery prolong hospital admission and convalescence and may lead to more serious morbidity with prosthetic graft infection, false aneurysm formation, or hemorrhage. Therefore, it is imperative to achieve wound closure as expeditiously as possible. Herein, we describe 11 patients with complicated groin wounds and report our management using sartorius myoplasty. Five of these patients had underlying prosthetic grafts at risk. All patients underwent wound closure with sartorius myoplasty after adequate debridement of necrotic and infected soft tissue. Success of wound closure with complete primary healing was observed in nine patients, while in two, adequate early coverage of femoral vessels was achieved, but extended wound care for superficial skin separation was necessary with eventual complete healing. There was no morbidity or mortality related to the added surgical procedure. One patient underwent late repair of a femoral false aneurysm. There were no other complications seen after an average follow-up of 20 months (range: 6 to 49 months). In summary, we recommend that sartorius myoplasty be considered for wound infections to hasten groin closure, decrease hospital stay, and reduce the chance of infectious complications.  相似文献

OBJECTIVE: To assess the complications related to intravenous drug abuse. DESIGN: Prospective study. METHODS: Intravenous drug abusers (IVDAs) with vascular complications were assessed. RESULTS: Sixty-two patients presented with swelling and tenderness in the groin, and 3 patients with similar lesions in the cubital fossa. Infected pseudoaneurysms and deep vein thrombosis (DVTs) were diagnosed in 41 and 31 patients respectively (27 patients had both lesions). In patients with infected pseudoaneurysms, 9 patients underwent excision with early revascularization and 32 patients underwent ligation without revascularization. For all patients with femoral vein thrombosis ligation and excision was performed. 4 patients with pure DVTs were managed conservatively. Disabling claudication occurred in 6 patients. Four of them underwent late revascularization with an acceptable outcome. CONCLUSIONS: Ligation without revascularization is the appropriate treatment of infected pseudoaneurysms in IVDAs. Late revascularization is of great importance in patients with disabling claudication after treatment of addiction. Pure septic DVTs can be managed conservatively.  相似文献

PURPOSE: This study evaluated the risk factors and surgical management of complications caused by femoral artery catheterization in pediatric patients. METHODS: From January 1986 to March 2001, the hospital records of all children who underwent operative repairs for complications caused by femoral artery catheterization were reviewed. A prospective cardiac data bank containing 1674 catheterization procedures during the study period was used as a means of determining risk factors associated with iatrogenic femoral artery injury. RESULTS: Thirty-six operations were performed in 34 patients (age range, 1 week-17.4 years) in whom iatrogenic complications developed after either diagnostic or therapeutic femoral artery catheterizations during the study period. Non-ischemic complications included femoral artery pseudoaneurysms (n = 4), arteriovenous fistulae (n = 5), uncontrollable bleeding, and expanding hematoma (n = 4). Operative repairs were performed successfully in all patients with non-ischemic iatrogenic femoral artery injuries. In contrast, ischemic complications occurred in 21 patients. Among them, 14 patients had acute femoral ischemia and underwent surgical interventions including femoral artery thrombectomy with primary closure (n = 6), saphenous vein patch angioplasty (n = 6), and resection with primary anastomosis (n = 2). Chronic femoral artery occlusion (> 30 days) occurred in seven patients, with symptoms including either severe claudication (n = 4) or gait disturbance or limb growth impairment (n = 3). Operative treatments in these patients included ileofemoral bypass grafting (n = 5), femorofemoral bypass grafting (n = 1), and femoral artery patch angioplasty (n = 1). During a mean follow-up period of 38 months, no instances of limb loss occurred, and 84% of children with ischemic complications eventually gained normal circulation. Factors that correlated with an increased risk of iatrogenic groin complications that necessitated surgical intervention included age younger than 3 years, therapeutic intervention, number of catheterizations (>or= 3), and use of 6F or larger guiding catheter. CONCLUSION: Although excellent operative results can be achieved in cases of non-ischemic complications, acute femoral occlusion in children younger than 2 years often leads to less satisfactory outcomes. Operative intervention can provide successful outcome in children with claudication caused by chronic limb ischemia. Variables that correlated with significant iatrogenic groin complications included a young age, therapeutic intervention, earlier catheterization, and the use of a large guiding catheter.  相似文献

Over a 14-month period patients undergoing 144 percutaneous transluminal coronary angioplasty procedures were evaluated for the presence of complications at the femoral puncture site. After percutaneous transluminal coronary angioplasty each patient was examined by a surgeon, and then a color-flow duplex scan of the groin was obtained. On the initial scan eight pseudoaneurysms, three arteriovenous fistulas, one combined arteriovenous fistula-pseudoaneurysm, and one thrombosed superficial femoral artery were detected for a major vascular complication rate of 9%. Pseudoaneurysm formation was associated with the use of heparin after removal of the arterial sheath. Seven pseudoaneurysms (initial extravascular cavity size range 1.3 to 3.5 cm) were followed with weekly duplex scans, and all thrombosed spontaneously within 4 weeks of detection. The three patients with isolated arteriovenous fistulas were each followed for at least 8 weeks, and the arteriovenous fistulas persisted. Early surgical intervention for postcatheterization femoral pseudoaneurysms is usually unnecessary as thrombosis often occurs spontaneously. We would advocate an operative approach for pseudoaneurysms that are symptomatic, expanding, or associated with large hematomas. Iatrogenic femoral arteriovenous fistulas should be considered for elective repair, but this may be delayed for several weeks without adverse sequelae.  相似文献

BACKGROUND: Drug addiction is a global medical and public health-care problem. Infections of the groin and fossa cubitalis are a common clinical problem in these patients. Severe vascular complications are rare but if they occur, therapy is difficult and requires emergency management and surgery because of bleeding problems. METHODS: In a retrospective case series, we report on patients treated within an emergency setting in our hospital because of groin abscesses with vascular involvement between 2003 and 2006. The therapeutic concepts and results are reported and discussed in the context of a review of the international literature. RESULTS: We report on 4 patients with a long-standing history of i. v. drug abuse (average age 33, range 29-36 years). All were hepatitis C Ag positive and HIV negative. The general health and nutritional status were not compromised, all patients had one or more DVT in their medical history. In two cases, emergency surgery with revascularisation was necessary (after 2 days in one case and 4 weeks in the other) because of septic bleeding subsequent to abscess incision. Two patients underwent primary revascularisation because of pseudoaneurysms. The grafts were a saphenous vein patch and a superficial femoral artery patch in one and deep vein segments in two cases. In two cases, a sartorius muscle flap and VAC therapy were used to cover the defect. All patients survived, minor amputation became necessary in one case. CONCLUSION: Abscess excision and debridement have to be as complete as possible and primary revascularisation is the procedure of choice in cases of severe groin infection. In the case of large vessel involvement, abscess incision alone without revision of the vascular structures is dangerous because of subsequent complications like secondary ruptures. For this reason, these patients require intensive care and close monitoring. Successful treatment exclusively based on ligation is described in literature with regard to isolated lesions of the superficial or deep femoral artery. Because of the very common involvement of the femoral bifurcation, revascularisation is, however, necessary in most cases and should be performed with autologous grafts if possible. If complete covering of the defect is not possible, a sartorius muscle flap is a good choice. Primary wound closure can be problematic because of recurrences, therefore vacuum-assisted wound closure is a valuable addition to the overall therapeutic approach in these cases.  相似文献

OBJECTIVE: Use of percutaneous suture closure devices after catheter-based interventions is increasing. We recently have seen several severe femoral arterial wall infections after use of such devices. The purpose of this study was to examine the incidence, comorbid associations, and management of femoral arterial infections associated with percutaneous suture closure devices. METHODS: We retrospectively reviewed all infectious complications that occurred after 2223 consecutive cardiac catheterization procedures performed over 12 months in a university-affiliated community teaching hospital. Outcome variables included demographics, procedural details, infection, type of arterial reconstruction required, mortality, and limb loss. RESULTS: During this study, 822 patients received percutaneous suture devices. Infection developed in 6 patients (0.7%). The incidence of diabetes in the population undergoing percutaneous suture closure was 219 of 822 patients (26.6%). Three comorbid conditions, noted in multiple patients with infectious complications, included diabetes mellitus, obesity, and placement of a percutaneous suture closure device within the past 6 months. Invasive femoral endarteritis developed in 4 patients. Gram-positive cocci predominated in 4 patients. In 1 patient with polymicrobial infection catastrophic complications developed, including multiple anastomotic ruptures and hemorrhage. A new method of repair that incorporated double-thickness everted saphenous vein was used in 2 patients, and safe arterial closure was achieved. There was 1 late fatality on postoperative day 36. Limb salvage was achieved in all patients. CONCLUSIONS: Femoral endarteritis complicating percutaneous suture closure is a challenging new problem for vascular surgeons and can result in catastrophic complications. Customary techniques that use saphenous vein patch or interposition grafting are not adequate in all circumstances. Successful outcome requires operative exploration in patients with suspected infection. Removal of the percutaneous suture closure device and debridement to normal arterial wall is recommended in all patients with suspected femoral endarteritis, based on positive intraoperative Gram stains or abnormal appearance of the adjacent femoral artery. Early success with an autologous bolstered repair is reported. Caution is advised when considering the use of a percutaneous suture closure device in patients with comorbid conditions including diabetes, obesity, and previously implanted devices.  相似文献

The aim of the study was to report our clinical experience with the surgical treatment of iatrogenic pseudoaneurysms of the peripheral arteries. The study is a retrospective review of 101 consecutive patients (52 males, 49 females, mean age 66.2 years, range 33-86), with iatrogenic pseudoaneurysms of the peripheral arteries, surgically treated in a vascular unit from October 1990 to June 2006. Duplex ultrasound scanning was employed to support the clinical findings. The surgical treatment consisted in direct closure with polypropylene sutures and, occasionally, patch angioplasty or bypass. Ultrasound compression was effective in one of 4 small aneurysms (< 2.5). No limb loss occurred. There were 4 wound complications (3.9%), one pulmonary embolism (0.99%), and 3 deaths (2.9%), 2 of which not related to vascular repair and one secondary to femoral endoarteritis and septic shock, unrelated to previous implantation of a percutaneous femoral closure device. Although iatrogenic pseudoaneurysms of the peripheral arteries are rarely observed in clinical practice, a significant number of peripheral artery complications may occur after cardiac catheterisation and coronary angioplasty. Failure of conservative treatment requires a traditional surgical repair. The results of our series included a significant mortality rate (2.9%), resulting from the severity of cardiac disease in 2 cases and from the vascular repair itself in one case (femoral endoarteritis). These results substantiate the common observation that patients who require surgery for an iatrogenic pseudoaneurysm are often affected by advanced cardiovascular disease and are liable to suffer the occurrence of complications, with a high risk of death. Therefore, any surgical treatment should be performed with strict adherence to sound vascular surgical principles.  相似文献

Mycotic femoral pseudoaneurysms, particularly in the drug-abusing population, pose a difficult problem to the vascular surgeon. Management ranges from ligation with debridement to extra-anatomical bypass. This study reviewed the management of mycotic femoral pseudoaneurysms presenting in intravenous drug abusers to an inner city tertiary referral center. Between 2001 and 2006, 11 cases presenting in nine patients were treated. The mean age was 30.7 years with a male-to-female ratio of 1:2. Eight patients had a positive viral status for the human immunodeficiency virus and/or hepatitis C. Two patients re-presented with a contralateral pseudoaneurysm. A combination of groin pain and swelling was the most common presentation. Two patients presented with significant hemorrhage. The diagnosis was confirmed by ultrasound in the majority of cases. Nine cases were managed with arterial ligation and debridement of the necrotic tissue. The two remaining cases were managed with ultrasound-guided thrombin injection and arterial puncture closure. On follow-up, one patient required a below-knee amputation following reinjection into the postoperative wound site. One further patient underwent a fifth metatarsal amputation due to ischemia. Ligation and debridement are well tolerated in the majority of drug-abusing patients diagnosed with mycotic femoral pseudoaneurysms.  相似文献

In the last 10 years we have treated 28 patients with 33 groin infections involving a common femoral artery anastomosis of prosthetic arterial grafts (2 aortic Dacron grafts, 31 peripheral polytetrafluoroethylene grafts). Management included complete graft preservation for patent infected grafts (11 cases), subtotal excision of occluded infected grafts leaving an oversewn 2 to 3 mm graft remnant attached to a patent artery critical for limb survival (16 cases), and total graft excision with arterial oversewing or ligation for anastomotic bleeding (6 cases). Essential treatment adjuncts included (1) radical operative wound debridement, and (2) secondary revascularization by means of bypasses tunneled via lateral uninfected routes, and unusual approaches to uninvolved patent outflow arteries (i.e., the distal superficial or deep femoral or popliteal arteries) after isolation of the infected wound. Follow-up averaged 3 years (1 to 10 years). This plan of treatment resulted in an 11% (3/28) hospital mortality and an amputation rate of 13% (4/30 threatened limbs). Of the 25 survivors with 30 infected groin grafts, 87% (26) of the wounds healed uneventfully by secondary intention within 1 to 8 weeks (mean, 4 weeks) and have remained healed. One infected groin wound did not heal and required delayed total graft excision. Three patients had late anastomotic disruption with hemorrhage at 8 months, 2 years, and 4 years after initial treatment. This selected use of complete or partial graft preservation and other essential treatment adjuncts are proposed as a safer, easier method for managing infected prosthetic arterial grafts in the groin.  相似文献

PURPOSE: The purpose of this study is to identify the peripheral vascular complications associated with the use of percutaneous suture-mediated closure (PSMC) devices and compare them with postcatheterization femoral artery complications not associated with PSMC devices. METHODS: This is a retrospective review of all patients admitted to the vascular surgery service at the Chattanooga Unit of the University of Tennessee Department of Surgery with a peripheral vascular complication after percutaneous femoral arteriotomy between July 1, 1998, and December 1, 1999. The complications followed the use of PSMC devices (group I, n = 11) and traditional compression therapy (group II, n = 14) to achieve arterial hemostasis. Group II was subdivided into patients who required operative intervention (group IIA, n = 8), and those who were treated without operation (group IIB, n = 6). RESULTS: No significant difference was found between groups I and II with regard to age (P =.227), time to vascular surgery consultation (P =.987), or diagnostic versus therapeutic catheterization (P =.897). A significant difference was found with regard to mean pseudoaneurysm size (group I = 5.9 cm, group II 2.9 cm; P =.003). Ultrasound compression was successfully performed in 66.6% of group II patients, but no (0.0%) patient in group I responded to this therapy (P =.016). Groups I and IIA had a significant difference for mean estimated blood loss (group I = 377.2 mL, group II = 121.8 mL; P =.017) and requirement for transfusion (P =.013). More patients in group I required extensive surgical treatment (P =.007), with six of these patients requiring vein patch angioplasty during their treatment. More patients in group I also had infectious complications (n = 3) compared with group IIA (n = 1). CONCLUSION: In comparison with complications that follow percutaneous arteriotomy when PSMC devices are not used for hemostasis: (1) pseudoaneurysms after the use of PSMC devices are larger and do not respond to ultrasound compression, (2) complications associated with PSMC devices result in more blood loss and increased need for transfusion and are more likely to require extensive operative procedures, and (3) arterial infections after the use of PSMC devices are more common and require aggressive surgical management.  相似文献

Background  Vascular complications from intravenous drug abuse pose significant challenges to vascular surgeons. No formalized polices have been reached on surgical management of the resultant infected pseudoaneurysm. Methods  A retrospective review of all patients who underwent surgery for pseudoaneurysms due to chronic intravenous drug abuse from July 2005 to February 2008 was performed. Results  A total of 15 patients with infected pseudoaneurysms from chronic intravenous drug abuse were operated on during the study period. The sites of involvement were restricted to the femoral (86.7%) and brachial (13.3%) areas. The drug involved was buprenorphine (Subutex) in all cases. Pain over the limb swelling (100%), pulsatility (60%), and symptoms suggestive of septicemia (46.7%) were the most common symptoms. Staphylococcus aureus was present in 93.3%. Diagnosis was achieved clinically in 26.7%, by duplex ultrasonography in 60.0%, and by computed tomography (CT) angiography in 13.3%. In the two patients with brachial pseudoaneurysms, the brachial artery was ligated in one, and a basilic vein patch was used in the other. In the 13 patients with femoral pseudoaneurysms, the pseudoaneurysm was ligated and excised in 8 (61.5%), and immediate reconstructive bypass surgery was performed in 5 (38.5%). Two patients had critical ischemia after ligation and required reconstructive bypass surgery a few weeks later. Postoperative complications included claudication, digital gangrene, localized wound infection, and rebleeding. There was no associated mortality. Conclusions   Pseudoaneurysm from intravenous drug abuse continues to pose significant challenges to surgeons worldwide, ranging from an accurate diagnosis to the choice of surgery. The aims of surgery must be to achieve adequate débridement and control infection and hemorrhage. Any associated postoperative complications must be identified and dealt with.  相似文献

The incidence of arterial complications following femoral artery cannulation is low; however, with the increasing number of cardiac diagnostic and interventional procedures, vascular surgeons are being confronted with an increasing number of pseudoaneurysms and arteriovenous fistulas. Swelling and a painful pulsating groin masse are the most frequent presenting symptoms of a common femoral artery false aneurysm. We present the cases of 4 patients who had the unusual finding of a profunda femoral artery pseudoaneurysm after they had undergone cardiac catheterization or percutaneous transluminal coronary angioplasty. The only clinical sign of these patients was femoral neuropathy or neuropalsy caused by femoral nerve compression. Surgical repair of the pseudoaneurysm was successful in all patients. We discuss the reasons for this unusual finding and rare location for a pseudoaneurysm.  相似文献

Endovascular repair of aortic lesions requires large bore femoral access (up to 26?F) for transfemoral stent graft delivery. Surgical cut down of the common femoral artery is still the most frequently used technique for groin management in EVAR and TEVAR procedures even though it prolongs operating time, increases tissue trauma and is associated with a variety of potential complications. It has been shown that a total percutaneous access using closure devices can reduce operating time, tissue trauma and as a result the time to ambulation. An alternative technique to simplify groin management in endovascular procedures has been described in 1997 to avoid surgical cut down and the use of expensive closure devices. This technique is today known as the fascia suturing technique. After the percutaneous procedure is completed a small oblique incision is made in the groin fold on either side of the puncture site exposing the cribriform fascia and a deep paravascular suture of the fascia is performed followed by a self-closing knot to cover the common femoral artery access. The published literature is summarized and our clinical experiences with the fascia suturing closure technique, which has been exclusively used for closure of all large (16?C26?F) femoral access sites in a total of 110 groins over an 11-month period, are presented.  相似文献

Pseudoaneurysms following femoral arterial catheterization are increasingly common and are related to factors such as catheter size, periprocedural anticoagulation, hypertension, and improper technique. Ultrasound-guided compression as a noninvasive technique for repair of these lesions was prospectively evaluated in 16 patients whose mean age was 61 years. Nine patients were on anticoagulants and six had hypertension. All patients presented with an enlarging groin hematoma, a pulsatile mass, and/or a bruit following femoral catheterization. Seventeen femoral artery pseudoaneurysms, including one with an associated arteriovenous fistula, were detected using color-flow Doppler imaging. Three pseudoaneurysms thrombosed spontaneously. The remaining 14 were managed with compressive therapy lasting from 20 to 100 minutes. No complications were encountered during the compressions and 10 false aneurysms (71%) responded completely (mean time to thrombosis of 38 minutes). Two lesions responded partially to compression and there were two failures, the latter associated with excessive anticoagulation in one patient and a well-established pseudoaneurysm in the second patient. Only one pseudoaneurysm (6%) in the series required surgical correction. Ultrasound-guided compression of acute pseudoaneurysms in the groin is a safe, inexpensive, and effective method of treatment.We thank Brenda Scott, Tammy Kovacs, Lisa Ungar, and Alison Grzywnowicz in the ultrasound department at Victoria Hospital for the time and enthusiasm they devoted to this project.  相似文献

Purpose: The purpose of this study was to better define the associated risks and optimal management of groin lymphatic complications (GLC) after femoral artery reconstructive operations.Methods: Retrospective review of a vascular surgery registry for the last 15 years identified 2679 arterial operations requiring a groin incision. Forty-one GLC were recognized, 28 lymphocutaneous fistulas (LF) and 13 lymphoceles.Results: The incidence of GLC was 1.5% per patient or 1.2% per incision. The highest incidence of GLC was in patients having an aortobifemoral bypass for aneurysmal disease in a previously operated groin (8.1% per patient) and in those undergoing an isolated femoral procedure in a previously operated groin (5.3%). The lowest frequency of GLC was after femoropopliteal/tibial bypasses (0.5%). Twenty-nine patients (71%) were treated without operation with bedrest, intravenous antibiotics, and aggressive local wound care. Operative therapy with wound reexploration attempted identification and control of the leak site, and meticulous wound closure was used in 12 patients (29%). Lymph fistulas in patients undergoing reoperation (10/28) resolved sooner than in patients treated without operation (18/28) (9 ± 3 days vs 24 ± 3 days). Infectious wound complications with one resultant graft infection developed in five of 18 patients with LF who did not undergo reoperation. There were no wound or graft infections in the patients in the LF group treated with operation. Operative exploration of lymphoceles did not reduce hospital stay or infectious wound complications. Repetitive lymphocele aspiration did not affect rapidity of resolution or increase the infectious complications.Conclusion: GLC remain a troublesome complication of femoral arterial reconstruction. Early reoperation should be performed once a LF is diagnosed. Treatment for lymphoceles should be individualized, with neither operative nor nonoperative management showing clear superiority.

Iatrogenic injuries of the groin are becoming more common after increasingly sophisticated vascular intervention. These injuries are accurately detected by duplex and color Doppler ultrasonography. Recent treatment of these lesions by ultrasound-guided compression repair (UGCR) has been described. During a 1-year period we identified 18 femoral artery injuries, including 17 pseudoaneurysms and one arteriovenous fistula. Three of the pseudoaneurysms thrombosed spontaneously before attempted treatment. The remaining 15 lesions underwent a trial of UGCR. Successful closure was accomplished in 10 patients (56%). Seven of these lesions were successfully treated during the initial session, and thrombosis was accomplished after repeat compression in three additional lesions. Three patients who were given anticoagulants had a failed UGCR, but their pseudoaneurysms thrombosed after administration of anticoagulants was discontinued. Two patients had failed UGCR and required operation. Seven (88%) of eight patients who were not given anticoagulants were successfully treated. In contrast only two (29%) of seven patients given therapeutic doses of anticoagulant medication were successfully treated by the technique. There was no statistical difference between mean pseudoaneurysm diameter, mean width and length of pseudoaneurysm neck, or depth of pseudoaneurysm neck from skin surface in patients in whom successful initial closure was achieved when compared with those patients in whom the initial attempt failed. UGCR is a safe, simple, noninvasive technique that can be used to treat many femoral artery injuries that traditionally were treated with surgery. The technique can be applied by any laboratory that has the necessary ultrasonography equipment and is currently the method of choice for treating uncomplicated iatrogenic femoral artery injuries at our institution.  相似文献

Femoral artery pseudoaneurysms (PSA or false aneurysm) develop in about 1% of patients undergoing procedures that require femoral artery cannulation. PSA prolong hospitalization, consuming health-care resources, and result in significant morbidity. We designed a study to review the prevalence, risk factors, and treatment of PSA. We performed a retrospective, case-controlled study of patients diagnosed with PSA at a large, urban, tertiary-care teaching hospital. We reviewed 48 patients with PSA for our study. The estimated prevalence of PSA was 0.28%, with identical rates found for procedures done in the interventional radiology department and in the cardiac catheterization suite. Logistic regression identified three independent risk factors for developing PSA: being female (odds ratio 2.62), having an intervention performed (odds ratio 3.22), and not having a closure device used (odds ratio 10.2). Patients with PSA had longer hospital length of stay than that of patients without PSA. We found no statistically significant difference in failure or complication rates for the four treatment options and that spontaneous resolution of PSA does not correlate with its size. Thrombin injection and observation are effective, low-complication treatment options. Presented at the Southeastern Surgical Congress, Savannah, GA, February 9, 2003.  相似文献
