Purpose
To evaluate effectiveness and safety of embolization of congenital renal arteriovenous malformations (AVMs) using ethanol and/or coil according to angiographic type.Materials and Methods
Between August 2010 and October 2015, 11 patients (13 sessions; 10 women and 1 man; mean age, 50.8 y) with congenital renal AVMs were treated using ethanol and/or coils via 2 approaches (transarterial access or direct puncture). Demographics, clinical findings, diagnostic modalities, angiographic types, technical and clinical success rates, and complications were reviewed. Renal AVMs were classified into 3 angiographic types, and treatment was based on this classification.Results
Technical success rate was 91% (10/11), and clinical success rate was 100% (11/11). Of patients, 7 had type III AVMs, 3 had type I AVMs, and 1 had type II AVM. Embolic agents were ethanol in 5 patients, coils with ethanol in 3 patients, and coils in 3 patients. Of the 8 patients treated with ethanol, 6 had infarcted renal areas of 3.5%–30% (mean, 14.6%). After a mean follow-up period of 16.3 months, there was no evidence of recurrent AVMs on imaging or laboratory studies.Conclusions
Embolization of congenital renal AVMs via transarterial or direct percutaneous approaches using ethanol and/or coils based on a simple angiographic classification was safe and effective and elicited good outcomes. Most of the patients with congenital renal AVMs were women. 相似文献2.

Purpose
To investigate whether accessory vein embolization (AVE) improves long-term performance of salvaged nonmaturing arteriovenous fistulae (AVFs).Materials and Methods
This retrospective review included 72 patients who underwent percutaneous balloon angioplasty for salvage of nonmaturing AVFs between 2008 and 2014. AVE was performed on 32 patients between 2008 and 2011 (mean age, 59 y [range, 33–85 y]; men, n = 21; women, n = 11; upper arm, n = 17; forearm, n = 15), whereas the procedure was not performed on 40 patients after 2011 (mean age, 62 y [range, 28–85 y]; men, n = 26; women, n = 14; upper arm, n = 26; forearm, n = 14). Endpoints compared between groups included number of procedures required to achieve maturation, time to maturation, number of procedures required to maintain patency, and duration of primary and secondary patency after intervention.Results
There was no statistically significant difference in number of procedures to achieve maturation (2.1 ± 1.4 vs 2.4 ± 1.2; P = .24) or time to maturation (26.1 d ± 56.2 vs 41.1 d ± 54.6; P = .072) between AVE and no embolization groups. Primary (P = .21) and secondary patency (P = .14) after intervention were not significantly different between groups. The number of procedures performed to maintain patency after maturation was significantly greater in the AVE group for patients with forearm AVFs (0.11 ± 0.098 vs 0.04 ± 0.064 per patient year; P = .039) but not for patients with upper arm AVFs.Conclusions
AVE of AVFs after balloon angioplasty does not lead to significantly improved long-term outcomes. Percutaneous salvage of nonmaturing AVFs in the forearm without AVE resulted in a decreased number of interventions to maintain patency. 相似文献3.

Purpose
To evaluate the safety and efficacy of arteriovenous fistula (AVF) creation with a thermal resistance anastomosis device (TRAD).Materials and Methods
From January 2014 to March 2015, 26 patients underwent ultrasound (US)-guided percutaneous creation of proximal radial artery–to–perforating vein AVFs with a TRAD that uses heat and pressure to create a fused anastomosis. Primary endpoints were fistula creation, patent fistula by Doppler US, two-needle dialysis at the prescribed rate, and device-related complications.Results
Technical success rate of fistula creation was 88% (23 of 26). Procedure time averaged 18.4 minutes (range, 5–34 min), and 96% of anastomoses (22 of 23) were fused. At 6 weeks, 87% of AVFs (20 of 23) were patent, 61% (14 of 23) had 400-mL/min brachial artery flow, 1 patient was receiving dialysis, 2 fistulae had thrombosed, and 1 patient had died unrelated to the procedure. Eighty percent (16 of 20), 70% (14 of 20), and 60% (12 of 20) of patients were receiving dialysis at 3, 6, and 12 months; 4 patients died, 3 fistulae failed, and one patient was lost to follow-up. Overall, 87% of AVFs (20 of 23) had an additional procedure at a mean of 56 days (range, 0–239 d), including balloon dilation in 43% (n = 10), brachial vein embolization in 26% (n = 6), basilic vein ligation in 17% (n = 4), venous transposition in 30% (n = 7), and valvulotomy in 4% (n = 1). There were no major complications related to the device.Conclusions
Percutaneous AVFs created with a TRAD met the safety endpoints of this study. Midterm follow-up demonstrated intact anastomoses and fistulae suitable for dialysis. 相似文献4.

Renal arteriovenous fistula (AVF) is rare. Renal AVF complicated by aneurysm of the feeding artery presents a technical challenge
for endovascular treatment. We report a case managed by covered stenting of the renal artery aneurysm, coil embolization of
the fistula, and bare stenting of the aorta. 相似文献

Purpose
To prospectively analyze technical and clinical outcome of percutaneous thrombectomy aspiration using a vacuum-assisted thrombectomy catheter in acutely thrombosed dialysis arteriovenous fistula (AVF) and/or arteriovenous graft (AVG).Materials and Methods
From June 2016 to April 2017, 35 patients (average age, 61.8 y; range, 33–81 y) presenting with acute thrombosis of dialysis AVF and/or AVG were prospectively evaluated for mechanical thrombectomy using the Indigo System. Adjunctive therapies and procedure-related complications were noted. Technical success, clinical success, primary patency, primary assisted patency, and secondary patency of the dialysis fistula were assessed.Results
Mean follow-up time was 8.5 months (range, 3–12 months). Technical success was 97.1% (34/35 patients). Clinical success was 91.4% (32/35 patients). Complications included hematoma (n = 1), thrombosis < 24 hours (n = 1), and perforation (n = 1). Other mechanical/aspiration thrombectomy devices were used in 1 site to clear the thrombus burden (Arrow-Trerotola [2.8%; 1/35 patients] and Fogarty [5.7%; 2/35 patients]). Average procedure time was 38.1 minutes (range, 15–140 min). Average blood loss during the procedure was 122.5 mL (range, 50–300 mL). The 6-month primary patency, primary assisted patency, and secondary patency were 71%, 80%, and 88.5%. No risk factors for early dialysis fistula occlusion were identified. There was no 30-day mortality.Conclusions
Percutaneous mechanical thrombectomy aspiration of thrombosed dialysis AVF and/or AVG with a vacuum-assisted thrombectomy catheter is a safe procedure with a low complication rate and effective method for restoring patency before hemodialysis. 相似文献6.

PurposeTo investigate and compare venous sac and feeding artery embolization (VFE) with feeding artery embolization (FAE) alone for treatment of pulmonary arteriovenous malformations (PAVMs), based on difference in outcomes in decrease of the size of the draining vein.Materials and MethodsTwenty-six patients (7 male and 19 female; median age [interquartile range], 58 years [46–65 years]) with 42 simple PAVMs treated with coil embolization between August 2005 and December 2018 were retrospectively evaluated. Twenty PAVMs were treated with FAE early in the study period and compared with 22 PAVMs treated with VFE later in the study period. Follow-up computed tomography images obtained 8–20 months after embolotherapy were used for outcome analysis. Data related to patient demographics; follow-up period; baseline diameters of the feeding artery, venous sac, and draining vein; draining vein diameter after treatment; and decrease in the size of the draining vein, including the number reaching a threshold of 70% decrease, were compared between the 2 groups.ResultsThe draining vein decreased in size by a median of 46.4% in the FAE group and 66.3% in the VFE group, and the difference between the 2 groups was statistically significant (P = .009). There were no significant differences in the other parameters.ConclusionsVFE leads to a greater decrease in the size of the draining vein than FAE, suggesting that VFE results in more complete occlusion than FAE for treatment of PAVMs. 相似文献

PurposeTo examine the efficacy of venous sac embolization (VSE) in comparison with transcatheter feeding artery embolization (FAE) for treatment of pulmonary arteriovenous malformations (PAVMs).Materials and MethodsFrom 1989–2009, 21 patients underwent embolization of 37 PAVMs. Safety and long-term efficacy of VSE were evaluated retrospectively and compared with FAE.ResultsFAE was performed in 22 (18 simple and 4 complex type) PAVMs, and VSE was performed in 15 (14 simple and 1 complex type) PAVMs. There were significant differences between FAE and VSE in treated periods, PAVM location, coil type used, number of coil combinations and coils per PAVM, coil position, and reperfusion; there were no significant differences in most PAVM characteristics, follow-up durations (58 mo±54 vs 42 mo±42; P= .32), and minor complications (pleurisy [2 vs 2]). Reperfusion occurred in 11 (50%) of 22 PAVMs in the FAE group and no PAVMs in the VSE group (P<.01). Of 22 PAVMs in the FAE group, 17 (77%) were treated with 0.035-inch coils alone; of 15 PAVMs in the VSE group, 14 (93%) were treated with 0.018-inch interlocking detachable coils (IDCs), 0.018-inch pushable fibered coils, or IDCs and pushable fibered coils combined (P<.01). The number of coils used was 8±4 in the VSE group and 4±4 in the FAE group (P= .002).ConclusionsThe high reperfusion rate in the FAE group was mainly due to the use of large 0.035-inch coils alone. Although more coils are needed, VSE can be used to treat PAVMs with a venous sac safely and achieve long-term efficacy. 相似文献

PurposeTo evaluate the technical and clinical success rates and safety of bilateral gelfoam uterine artery embolization (UAE) for symptomatic acquired uterine arteriovenous shunting due to prior obstetric or gynecologic event.Materials and MethodsThis was a retrospective study of consecutive patients of reproductive age who presented with abnormal uterine bleeding after recent gynecologic procedures or obstetric events between January 2013 and February 2018. Bilateral UAE was performed in all patients using gelfoam slurry. Technical success was defined as angiographic resolution of arteriovenous shunting. Clinical success was defined as cessation of symptomatic bleeding, resolution on follow-up imaging, or minimal estimated blood loss (EBL) (<50 ml) on subsequent elective dilation and curettage (D&C) procedure.ResultsEighteen patients (mean age, 32.8 ± 7.1 years) were included. Technical success and clinical success were experienced by 17/18 (94.4%) and 16/17 (94.1%) patients, respectively. Angiography demonstrated arteriovenous shunting in 18/18 (100%) patients, with early venous drainage. Seven of 18 (38.9%) patients underwent subsequent scheduled D&C due to remaining retained products of conception, with an EBL of 17.9 ± 15.6 ml. There was 1 minor complication of a self-limited vascular access groin hematoma (1/18, 5.6%) and 1 major complication (1/18, 5.6%) of a pulmonary embolism detected 3 days after UAE. The length of clinical follow-up was 19.3 ± 15.5 months, in which 41.2% (7/17) of the patients became pregnant.ConclusionsUAE with gelfoam alone for symptomatic uterine arteriovenous shunting is a feasible treatment option that has a high technical and clinical success rate with a low rate of complications. 相似文献

Purpose
To evaluate the influence of percutaneous cryoablation for renal cell carcinoma on function of the affected kidney.Materials and Methods
Between June 2016 and September 2017 at our institution, 12 inoperable patients underwent 15 cryoablation sessions for 17 small renal tumors. Of these, 9 patients who underwent 11 sessions of cryoablation were the focus of this study. For those patients, time-dependent changes in postoperative renal function were investigated by a retrospective review of clinical records. Evaluated were the estimated glomerular filtration rate (eGFR) and scintigraphy using 99m technetium-mercaptoacetyltriglycine (99mTc-MAG3) before and 1 week, 1–2 months, and more than 6 months after cryoablation.Results
Mean baseline eGFR was 76.88 ± 29.82 mL/min/1.73 m2 (mean ± standard deviation; range, 23.4–112.5). Mean eGFR 1 week, 1–2 months, and more than 6 months after cryoablation were 74.56 ± 26.68 mL/min/1.73 m2 (21.0–101.1), 69.5 ± 25.28 mL/min/1.73 m2 (24.1–105.6), and 75.08 ± 26.25 mL/min/1.73 m2 (29.0–107.3), respectively. Changes were statistically insignificant (P = .6044, P = .6699, and P = .9038, respectively). Regarding split renal function, the mean baseline contribution of the affected kidney determined by 99mTc-MAG3 was 47.27% ± 6.14 (38.8%–57.0%). Mean contributions of the affected kidney 1 week after, 1–2 months after, and more than 6 months after cryoablation were 44.40% ± 5.37 (38.3%–53.6%), 44.57% ± 6.52 (34.35%–55.0%), and 45.41% ± 7.77 (34.4%–56.5%), respectively. Differences from baseline were significant for the earliest 2 periods (P = .0473 and P = .0334, respectively) but not the later period (P = .2532).Conclusions
Results suggested that total renal function does not worsen after cryoablation; however, function of the affected kidney worsened after cryoablation but later partially recovered. 相似文献13.

PurposeTo evaluate treatment outcomes of embolization for peripheral arteriovenous malformations (AVMs) in a tertiary referral center where ethanol is the primary agent of choice.MethodsA retrospective study was performed of 93 patients (median age, 31 years; range, 2–66 years) with peripheral AVMs treated with embolization (n = 442; median, 2 per patient; range, 1–82) between January 2010 and July 2016. Ethanol was used in most cases (n = 428; 97%). AVMs were classified as type I (n = 3), type II (n = 57), type IIIa (n = 5), type IIIb (n = 15), and type IV (n = 13) according to the Yakes classification system. Effectiveness of embolization was based on AVM devascularization on angiography: 100% (total), 90%–99% (near-total), 70%–90% (substantial), 30%–70% (partial), and 0%–30% (failure). Complications were graded according to the Society of Interventional Radiology classification.ResultsIn 69% of patients, 70%–100% devascularization was achieved. Total and near-total occlusion of the nidus were more often achieved in AVMs of types I and IIIa (both 100%) than in AVMs of types II, IIIb, and IV (56%, 67%, and 39%, respectively; P = .019). A total of 109 complications were identified: 101 minor (22.9%) and 8 major (1.8%). Major complications included wounds (n = 5), false aneurysm (n = 1), finger contracture (n = 1), and severe pain (n = 1) requiring therapy. The patient complication risk was significantly affected by the number of procedures (relative risk = 2.0; P < .001). Age, AVM location, and angioarchitecture type did not significantly affect complication risk.ConclusionsAVM embolization resulted in 70%–100% devascularization in 69% of patients, with few major complications. This study indicates that the type of AVM angioarchitecture affects the number of procedures needed and the achievability of AVM devascularization. 相似文献

A New Device for Vascular Embolization: Report on Case of Two Pulmonary Arteriovenous Fistulas Embolization Using the Amplatzer Vascular Plug 总被引:8,自引:4,他引:4

A pulmonary arteriovenous fistula (PAVF) is a rare vascular malformation commonly treated by embolization with coils or balloons
to prevent the risk of several serious complications such as cerebral embolism and brain abscess. A 32-year-old female with
two PAVFs and neurological ischemic manifestations has been successfully treated by transcatheter embolization of both fistulas
using a new device (Amplatzer Vascular Plug). This self-expanding cylindrical nitinol mesh cage with high radial strength
allows a chance of relocation until properly positioned. It is preferred to coils or balloons because a large caliber of feeding
artery implied high risk of uncontrollable distal embolization. There appear to be no reports in the literature concerning
use of this device, which could represent a useful innovative tool in embolotherapies, especially in large vascular areas. 相似文献

Percutaneous transcatheter embolization has become the treatment of choice for pulmonary arteriovenous fistulas (PAVFs), in most cases replacing surgical intervention. However, while "classic" devices, such as intravascular coils and detachable balloons, have proved to be successful for interventional occlusions of small or medium-sized PAVFs, they are not ideal in larger fistulas because of the risk for embolization to the systemic circulation. We describe the case of a 61-year-old woman with a symptomatic huge solitary pulmonary arteriovenous fistula (4.5 cm in diameter), occupying part of the lung in the lower right lobe with two feeding arteries (10 and 4 mm in diameter, respectively), who underwent successful transcatheter closure with an Amplatzer Vascular Plug, a new device designed for the occlusion of vascular abnormalities. 相似文献

PurposeTo assess the efficacy and safety of the AMPLATZER Vascular Plug type IV for pulmonary arteriovenous malformation (PAVM) treatment.Materials and MethodsBetween June 2013 and January 2018, 13 patients with 26 PAVMs were treated with the type IV AVP. Patients without follow-up computed tomography (CT) were excluded. Technical success was defined as flow occlusion on angiography. Plug-to-sac distance was measured on angiographic images. Feeding artery and venous sac diameter changes were measured on preprocedural and follow-up CT. Successful embolization was defined as > 70% sac size regression. Procedure time, device migration, and complications were evaluated.ResultsNine female patients (mean age, 49 y; range, 40–71 y) with 19 PAVMs were enrolled. Four patients with 7 PAVMs were lost to follow-up. Nineteen PAVMs were treated in 11 sessions, and the mean procedure time was 29 min. The technical success rate was 100%. Mean feeding artery diameter was 3.1 mm ± 0.7 (range, 2.1–4.9 mm). Mean plug-to-sac distance was 5.4 mm ± 4.9 (range, 0–13.3 mm). The mean CT follow-up period was 14 months ± 7 (range, 6–30 mo). Sixteen of 19 PAVMs (84%) were successfully embolized. Minor complications (tachycardia and chest discomfort) arose in 2 of 11 sessions. No device migrations or major complications occurred.ConclusionsThe type IV AVP showed an 84% treatment success rate based on 70% sac size regression criteria in small PAVMs. There were no device migrations or major complications. 相似文献

Purpose
To determine incidence, predictors, and clinical outcomes of postcontrast acute kidney injury (PC-AKI) following renal artery stent placement for atherosclerotic renal artery stenosis.Materials and Methods
This retrospective study reviewed 1,052 patients who underwent renal artery stent placement for atherosclerotic renal artery stenosis; 437 patients with follow-up data were included. Mean age was 73.6 years ± 8.3. PC-AKI was defined as absolute serum creatinine increase ≥ 0.3 mg/dL or percentage increase in serum creatinine ≥ 50% within 48 hours of intervention. Logistic regression analysis was performed to identify risk factors for PC-AKI. The cumulative proportion of patients who died or went on to hemodialysis was determined using Kaplan-Meier survival analysis.Results
Mean follow-up was 71.1 months ± 68.4. PC-AKI developed in 26 patients (5.9%). Patients with PC-AKI had significantly higher levels of baseline proteinuria compared with patients without PC-AKI (odds ratio = 1.38; 95% confidence interval, 1.11–1.72; P = .004). Hydration before intervention, chronic kidney disease stage, baseline glomerular filtration rate, statin medications, contrast volume, and iodine load were not associated with higher rates of PC-AKI. Dialysis-free survival and mortality rates were not significantly different between patients with and without PC-AKI (P = .50 and P = .17, respectively).Conclusions
Elevated baseline proteinuria was the only predictor for PC-AKI in patients undergoing renal artery stent placement. Patients who developed PC-AKI were not at greater risk for hemodialysis or death. 相似文献18.

Long-term follow-up results after embolization of 13 pulmonary arteriovenous malformations in 10 patients by use of 14 detachable
silicone balloons are given. Patients were followed for a mean of 99 months (range, 63–123 months) with chest x-rays and for
a mean of 62 months (range, 3–101 months) with pulmonary angiography. Fifty-four percent of the balloons were deflated at
latest radiographic chest film follow-up, but at pulmonary angiographic follow-up all embolized malformations were without
flow irrespective of whether or not the balloons were visible. Detachable silicone balloons are not available anymore, but
use of these balloons for embolization of pulmonary arteriovenous malformations has been shown to be a safe and precise method,
with immediate occlusion of the feeding artery and with long-lasting occlusion, even though many balloons deflate with time,
leaving a fibrotic scar replacing the pulmonary arteriovenous malformation. No case of recanalization has been discovered,
and these results seem to justify a reduced number of controls of these balloon-embolized malformations. 相似文献
