Effects of bilateral hypogastric artery interruption during endovascular and open aortoiliac aneurysm repair

PURPOSE: Hypogastric artery interruption is sometimes required during aortoiliac aneurysm repair. We have not experienced some of the life-threatening complications of pelvic ischemia reported by others. Therefore we analyzed our experience to identify factors that help minimize pelvic ischemia with unilateral and bilateral hypogastric artery interruption. METHODS: From 1995 to 2003, 48 patients with aortoiliac aneurysm required interruption of both hypogastric arteries as part of endovascular (n = 32) or open surgical (n = 16) repair. During endovascular aneurysm repair coils were placed at the origin of the hypogastric arteries, and bilateral hypogastric artery interruptions were staged at 1 to 2 weeks when possible. Open surgery necessitated oversewing or excluding the origins of the hypogastric arteries and extending the prosthetic graft to the external iliac or femoral artery. Collateral branches from the external iliac and femoral arteries were preserved, and patients received systemic heparinization (50 units/kg). RESULTS: There was no buttock necrosis, ischemic colitis requiring colon resection, or death with the bilateral hypogastric artery interruption. Initially buttock claudication developed in 20 patients (42%), but persisted in only 7 patients (15%) at 1 year. New onset of impotence occurred in 4 of 28 patients (14%), and there were no neurologic deficits. CONCLUSIONS: Bilateral hypogastric artery interruptions can be accomplished with limited morbidity. When hypogastric artery interruption is needed during endovascular aneurysm repair, certain principles help minimize pelvic ischemia. These include hypogastric artery interruption at its origin to preserve the pelvic collateral vessels, staging bilateral hypogastric artery interruptions when possible, preserving collateral branches from the femoral and external iliac arteries, and providing adequate heparinization of the patient during these procedures.     

Combined coronary and femoral revascularization for the treatment of hypoplastic aortoiliac syndrome: Report of a case

The coronary artery and aortoiliac occlusive disease frequently coexist and in relatively rare instances, a complication of hypoplastic aortoiliac syndrome (HAIS) may occur. We herein present our experience with a 51-year-old female patient with HAIS and concomitant coronary artery disease. She underwent a successful simultaneous coronary and femoral revascularization. The left anterior descending artery was bypassed with the in situ gastroepiploic artery and a biaorto-external iliac artery bypass was performed with expanded polytetrafluoroethylene precuffed grafts. She had a good postoperative course, with no angina or intermittent claudication. The importance of the technical aspects of reconstructive surgery in patients with HAIS has been emphasized in many reports in the literature, and the surgical options for combined coronary and femoral revascularization are also discussed herein.     

Glutealnekrose nach Ausschaltung eines rupturierten Iliakalaneurysmas

Chronic hypoperfusion of the hypogastric arteries due to aortoiliac surgery leads to a complex of symptoms well known as Lerich's syndome. In contrast, acute ischemia of the pelvic arterial tree leads to lethal complications [2, 4, 5, 9, 10, 12, 13]. Acute interruption of the hypogastric perfusion mainly occurs after aortoiliac surgery or after selective transcatheter embolisation of the internal iliac artery for control of pelvic bleeding [1, 8]. Several complications may occur after total occlusion: urinary bladder necrosis [6], left colon ischemia, spinal cord ischemia [10], nerve palsy, necrosis of the rectum and gluteal musculature [2, 11–13]. Despite adequate therapy, mortality is over 70% [2]. We report the case of a 66-year-old patient who survived after acute occlusion of the iliac arteries with gluteal necrosis following replacement of the infrarenal aorta with an aortobiiliacal graft.     

Direct Hypogastric Artery Reconstruction for Threatened Lower Limb Ischemia: Report of a Case

The hypogastric artery is one of the major collateral arteries in aortoiliac occlusive disease. This report describes a case of limb-threatening ischemia caused by acute arterial thrombosis of the right hypogastric artery. The external iliac and distal arteries were obstructed and the hypogastric artery was a major collateral artery. A diagnostic arteriogram taken after intra-arterial thrombolytic therapy revealed a stenotic lesion in the orifice of the hypogastric artery. Open thromboendarterectomy of the hypogastric artery and patch angioplasty, using an expanded polytetrafluoroethylene graft, were performed to salvage the limb. The hypogastric artery was successfully revascularized and ischemic rest pain was relieved. Received: January 14, 2000 / Accepted: September 26, 2000     

The critical hypogastric circulation

Eleven patients had ischemic complications secondary to ligation, hypoperfusion, exclusion, or thrombosis of the hypogastric arteries after aortoiliac reconstruction or spontaneous aortoiliac thrombosis. Ligation of one hypogastric artery resulted in persistent ipsilateral buttock claudication in three patients. Bilateral acute hypogastric artery ischemia occurred in eight patients and resulted in paralysis in all eight patients, buttock necrosis in four patients, anal and bladder sphincteric dysfunction in two patients, and colorectal ischemia in three patients. Five of these patients (63 percent) died. The mortality rate was 100 percent when buttock necrosis developed. In most of these patients, the neurologic deficit suggested ischemic injury of the lumbosacral plexus rather than spinal cord ischemia. These complications occurred despite patent bypass grafts to the iliac or femoral vessels. These observations suggest that it is essential to maintain patency of the hypogastric vessels in all aortoiliac reconstructions.     

A novel hybrid approach to the treatment of common iliac aneurysms: antegrade endovascular hypogastric stent grafting and femorofemoral bypass grafting

A progressively enlarging left common iliac artery aneurysm developed in a 72-year-old man 7 years after open abdominal aortic aneurysm repair with a bifurcated Dacron graft. Because both the right hypogastric and inferior mesenteric arteries had been ligated at the initial operation, preservation of left hypogastric flow was critical to avoid pelvic or intestinal ischemia. He was a poor open surgical candidate owing to obesity, a hostile abdomen, and multiple medical comorbidities. Therefore, a novel hybrid approach was used consisting of left transbrachial selective left hypogastric artery catheterization, followed by deployment of two, overlapping, antegrade, covered stent grafts extending from the proximal left graft limb into the left hypogastric artery. A right-to-left femorofemoral crossover bypass was added to perfuse the left lower extremity and was performed in end-to-end fashion to the left common femoral artery to exclude and prevent retrograde flow into the iliac aneurysm. Also presented are potential procedural pitfalls and a detailed review of open, endovascular and hybrid options to preserve hypogastric flow when treating iliac aneurysms in complex, high-risk patients.     

Internal iliac artery revascularization as an adjunct to endovascular repair of aortoiliac aneurysms.

PURPOSE: Endovascular repair of aortoiliac aneurysms may be limited by extension of the aneurysm to the iliac bifurcation, necessitating endpoint implantation in the external iliac artery. In such cases the circulation to the internal iliac artery is interrupted. Bilateral internal iliac artery occlusion during endovascular repair may be associated with significant morbidity, including gluteal claudication, erectile dysfunction, and ischemia of the sigmoid colon and perineum. We have employed internal iliac artery revascularization (IIR) to allow endograft implantation in the external iliac artery while preserving flow to the internal iliac artery in patients with aneurysms involving the iliac bifurcation bilaterally. METHODS: A total of 11 IIR procedures were performed in 10 patients undergoing endovascular abdominal aortic aneurysm (AAA) repair (9 men, 1 woman; mean age, 74 years). IIR was accomplished via a retroinguinal incision in 9 cases and a retroperitoneal incision in 2 cases. Six-mm polyester grafts were used for external-to-internal iliac artery bypass in 10 cases and internal iliac artery transposition onto the external iliac artery was used in one case. Endovascular AAA repair was performed using a modular bifurcated device (Talent-LPS, Medtronics, Minneapolis, Minn) after IIR. Bypass graft patency was determined immediately after the surgery, at 1 month, and every 3 months thereafter, using duplex ultrasound scanning and computed-tomography angiography. Mean aneurysm diameters were as follows: AAA, 6.4 +/- 0.7 cm; ipsilateral common iliac, 3.7 +/- 1.0 cm; contralateral common iliac, 3.9 +/- 0.8 cm. RESULTS: Successful IIR and endovascular AAA repair were accomplished in all cases. No proximal, distal, or graft junction endoleaks occurred. Two patients demonstrated retrograde aneurysm side-branch endoleaks originating from the lumbar arteries. One thrombosed spontaneously within 3 months. One perioperative myocardial infarction occurred. Reduction in aneurysm size was documented in 5 aortic, 5 ipsilateral iliac, and 3 contralateral iliac aneurysms. Gluteal claudication, erectile dysfunction, colon and perineal ischemia, and mortality did not occur. All IIRs have remained patent during a follow-up period of 4 to 15 months (mean, 10.1 months). CONCLUSIONS: IIR may be used with good short-term to intermediate-term patency to prevent pelvic ischemia in patients whose aneurysm anatomy requires extension of the endograft into the external iliac artery. This may allow endovascular AAA repair to be performed in patients who might otherwise be at risk for developing complications associated with bilateral internal iliac artery occlusion.     

A technique for combined hypogastric artery bypass and endovascular repair of complex aortoiliac aneurysms

Endovascular repair of complex aortoiliac aneurysms may necessitate distal fixation of the endograft to the external iliac artery and percutaneous embolization of the hypogastric artery for prevention of a retrograde endoleak. However, acute interruption of hypogastric perfusion can result in symptoms of pelvic ischemia. We describe a technique in which a prosthetic graft is used as an external iliac artery conduit to facilitate the passage of the endograft delivery catheter/sheath and after completion of the endovascular portion of the procedure, a surgical bypass is completed with anastomosis of the graft to the hypogastric artery.     

Technique for iliac artery reconstruction in abdominal aortic aneurysm repair.

The aim of this retrospective study was to evaluate the technique for iliac artery reconstruction in abdominal aortic aneurysm repair, when external and internal iliac arteries were required to reconstruct individually. Among 203 elective infrarenal abdominal aortic aneurysm repairs, 22 patients (10.8%) required individual reconstruction of bilateral or unilateral iliac arteries, including 56 external or internal iliac arteries. Mainly, three types of procedures were performed: (1) the external iliac artery was anastomosed to the end of the bifurcated graft limb in an end-to-end manner, and the internal iliac artery was attached to the side of the external iliac artery, (2) the external iliac artery was anastomosed to the end of the bifurcated graft limb in an end-to-end manner and the internal iliac artery was bypassed with the use of a straight prosthetic graft extending from the limb of the bifurcated graft, and (3) the internal iliac artery was anastomosed to the end of the bifurcated graft limb in an end-to-end fashion, and the external iliac artery was sewn to the side of the graft limb. In these three types of procedures, the third technique was the easiest and simplest anatomically.     

Use of an aortic bifurcation-sparing endograft facilitates hypogastric preservation during aortoiliac aneurysm repair

A significant percent of patients undergoing endovascular abdominal aortic aneurysm repair (EVAR) have concomitant common iliac artery aneurysms. While most of these patients will tolerate sacrifice of the hypogastric artery during repair, a subset will develop sequelae of hypogastric occlusion. EVAR was performed in two patients using a bifurcation-sparing unibody endograft (Powerlink, Endologix, Irvine, CA, USA). To avoid simultaneous bilateral hypogastric occlusion, one side was treated with coil embolization while the other was treated with a hypogastric graft (Viabahn, W L Gore and Associates, Flagstaff, AZ, USA). Access to the preserved hypogastric artery was obtained from a sheath inserted from the contralateral femoral artery and brought over the aortic bifurcation with the assistance of a 'rail-wire' traversing from the contralateral to ipsilateral femoral sheaths. The hypogastric limb was deployed simultaneously with the ipsilateral external iliac limb extension, creating a double-barrel flow lumen preserving both hypogastric and external iliac flow. At a mean follow-up of 5.1 months, both hypogastric limbs are patent and no endoleaks were observed. In conclusion, until commercially-produced branched hypogastric endografts are widely available, techniques such as those described above can allow for hypogastric preservation during aortoiliac aneurysm repair without the need for device modification or brachial access for hypogastric limb delivery.     

Migration of a bifurcated endovascular graft into an iliac aneurysm: endovascular salvage and future prevention--a case report

The FDA approval of endovascular grafts for the treatment of abdominal aortic aneurysms has been associated with a dramatic increase in the use of these devices. Major referral centers are reporting the treatment of 75% to 80% of their patients with infrarenal abdominal aortic aneurysms with endovascular devices. The large quantity of endovascular devices being used has produced a growing number of management issues that are often not predictable during the preoperative assessment. These issues require complex intraoperative decision making and innovative techniques for their management as reflected by the subsequent case report. An 82-year-old patient presented with a 7.8-cm abdominal aortic aneurysm. The aneurysm extended into the common iliac arteries bilaterally. The right common iliac artery was 6.5 cm and the left common iliac artery was 2.0 cm in maximal diameter. The preoperative work-up, including a computed tomography scan and arteriogram, suggested that he would be a potential candidate for endovascular repair. The plan was to extend the graft into the right external iliac artery after embolization of the right hypogastric artery and to seal the left limb in the ectatic left common iliac artery using an aortic extender cuff. During the endovascular repair of the aortoiliac aneurysms using the AneuRx bifurcated graft, the main device became dislodged from its infrarenal attachment site and migrated into the large right common iliac artery aneurysm with the iliac limb ending in the distal external iliac artery. A new bifurcated device was deployed from the left side to attempt an endovascular salvage of the difficult situation. The new graft was partially deployed down to the iliac limb. This allowed cannulation of the contralateral stump through the original endovascular graft that had migrated distally. The two grafts were connected with a long iliac limb. This allowed stabilization of the endovascular reconstruction by increasing its columnar strength. The deployment of the second bifurcated graft was completed and the central core with the runners removed safely without migration of the second bifurcated component. The reconstruction was completed with an aortic cuff in the left common iliac artery. The use of the aortic cuff was useful to preserve the left hypogastric artery. No intraoperative endoleak was noted. The patient did well and was discharged the day following the procedure. The follow-up computed tomography scan shows the abdominal aortic aneurysm excluded by the endovascular graft with a defunctionalized portion of one bifurcated graft within the right common iliac aneurysm. There is no evidence of endoleak and the abdominal aortic aneurysm had decreased in size at 6 months. This case demonstrates one of the unique management problems that may arise during endovascular graft placement. Events that initially would suggest failure of the endoluminal treatment may be corrected using advanced endovascular techniques by an experienced surgeon. However, there will be times that the prudent decision will be conversion to open repair. Only good clinical judgement and adequate training will prevent catastrophic outcomes.     

Bypass to the lateral circumflex femoral artery

Two patients with severe aortoiliac disease presented with total occlusion of all major femoral arteries, including the distal profunda femoris artery. Bypass to the lateral circumflex femoral artery, the most proximal branch of the profunda femoris artery, was successful in each patient. One patient had a bifurcated Dacron graft implanted from the aorta to the lateral circumflex femoral artery on each side. No sequential bypass to more distal vessels has since been necessary. The second patient underwent bypass to the lateral circumflex femoral artery from the contralateral femoral artery using saphenous vein. The procedure obviated the need to revise an above-knee amputation. The lateral circumflex femoral artery can provide suitable outflow in patients with thrombosis of the entire profunda femoris artery.Presented at the Tenth Annual Meeting of the Southern California Vascular Surgical Society, September 27–29, 1991, Marina Del Rey, California.     

Hypogastric artery embolization in endovascular abdominal aortic aneurysm repair

PURPOSE: Iliac artery anatomy is a central factor in endoluminal abdominal aortic aneurysm therapy. It serves as the conduit for graft deployment and as the region of distal graft seal. Thirty-eight percent of iliac vessels in our patients require special treatment because of aneurysms, tortuosity, or small size. Bilateral hypogastric artery exclusion has been avoided because of concerns of colorectal ischemia, hip/buttock claudication, and impotence. We suggest that elective, staged, bilateral hypogastric embolization can be performed safely with reasonably low morbidity and can expand the anatomic boundaries for stent-graft abdominal aortic aneurysm repair. METHODS: This study was performed as a retrospective chart review of patients requiring hypogastric artery embolization for endovascular repair of abdominal aortic aneurysms between June 1998 and June 2000. Patients with otherwise appropriate anatomy and common iliac artery aneurysms were informed of the option for stent-graft repair with internal iliac artery embolization with its risks of impotence, hip/buttock claudication, and bowel ischemia. Patients underwent unilateral or staged bilateral coil embolizations of their proximal hypogastric arteries with an approximate 1-week interval between procedures. Hospital and office records were reviewed; phone interviews were performed. Follow-up ranged from 1 to 12 months. RESULTS: During a 24-month period, 65 patients underwent endovascular abdominal aortic aneurysm repair; 18 patients (28%) required hypogastric artery embolization. Seven (39%) of these patients underwent bilateral embolization. There were no episodes of clinically evident bowel ischemia. Lactate levels were normal in all measured patients. Postoperative fevers (> 101.0 degrees F) were documented in 10 (56%) of 18 patients. The average white blood cell count was 12.8 x 10(9)/L (range, 8.5-22.9). There were no positive blood culture results. The return to the full preoperative diet occurred in 1 to 3 days. Hip/buttock claudication occurred in approximately 50% of patients with persistent but improved symptoms at 6 months. Eighty-seven percent of patients had preoperative erectile dysfunction. Only two patients noted worsening of erectile function postoperatively. CONCLUSIONS: Preliminary results indicate that bilateral hypogastric artery embolization can be performed, when necessary, with reasonable morbidity in patients undergoing stent-graft abdominal aortic aneurysm repair.     

Emergency endovascular treatment for ruptured abdominal aortic aneurysm and the risk of spinal cord ischemia

BACKGROUND: Spinal cord ischemia is a rare complication after open surgical repair for ruptured abdominal aortic aneurysms (rAAA). The use of emergency endovascular aortic aneurysm repair (eEVAR) is increasing, and paraplegia has been observed in a few patients. The objective of this study was to assess the incidence and pathogenesis of spinal cord ischemia after eEVAR in greater detail. METHODS: This was a retrospective analysis of patients who had eEVAR for rAAA in three hospitals in The Netherlands and Belgium during a 3-year study period that ended in February 2004. The use of aortouniiliac devices combined with a femorofemoral crossover bypass was the preferred technique. Patients with postoperative symptoms of spinal cord ischemia were identified and the influence of potential risk factors was assessed. These factors included the presence of common iliac artery aneurysms necessitating device limb extension to the external iliac artery with associated overlapping the hypogastric artery, the prolonged interruption of bilateral hypogastric artery arterial inflow during the procedure (defined "functional aortic occlusion time" >30 minutes), and the occurrence of preoperative hemodynamic shock. RESULTS: Thirty-five patients were treated by EVAR and they constituted the study group. The first-month mortality in the study group with EVAR was 23%. Four patients (11.5%) with EVAR developed paraplegia postoperatively; the unilateral or bilateral hypogastric artery in all four patients became occluded during the procedure. In the other 31 patients who did not have paraplegia, the unilateral or bilateral hypogastric arteries became occluded in 14 patients (45%). This constituted a significant difference in the prevalence of hypogastric artery occlusion in patients with or without paraplegia (P = .04). The functional aortic occlusion time was prolonged in all four patients with paraplegia and in five without spinal cord ischemia (P = .0003). All four patients with spinal cord ischemia presented with hemodynamic shock. This factor did not reach a significant difference from nonparaplegic patients. CONCLUSION: Emergency EVAR continues to be a promising approach to reduce the high mortality of rAAA, but the incidence of spinal cord ischemia after endovascular treatment of rAAA was worrisome. Although the pathogenesis is most likely multifactorial, interruption of the hypogastric artery inflow appeared to have significant influence. In patients with aneurysmatic common iliac arteries, any effort should be made to minimize hypogastric occlusion time during the procedure and to maintain hypogastric artery inflow afterwards, either by the use of a bell-bottom iliac extension or by electing open repair.     

Isolated hypogastric artery revascularization after previous bypass for aortoiliac occlusive disease

Patients with recurrent buttock claudication and/or impotence occurring after aortoiliac reconstruction, whose resting and postexercise vascular laboratory values are normal, represent an uncommon and poorly recognized problem resulting from occlusion of the bypassed iliac segments and ischemia isolated to the distribution of the hypogastric artery. This paradox and its solution are exemplified by two patients reported herein. In each instance flow was reestablished after thromboendarterectomy of the proximal hypogastric artery by connecting the artery to the functioning bypass.     

Pelvic ischemia following aortoiliac reconstruction

Clinically evident compromise of parietal or visceral pelvic function secondary to interruption of pelvic blood flow occurs infrequently after aortoiliac reconstruction. Certain patterns of aortoiliac or occlusive aneurysmal disease or graft infection may require exclusion of the hypogastric or profunda femoral arteries. In these situations collateral blood flow or retrograde iliac flow may be insufficient to perfuse the pelvis and may cause ischemia. We present three cases of postoperative pelvic ischemia and describe our efforts to restore pelvic perfusion.     

Endovascular aortounifemoral grafts and femorofemoral bypass for bilateral limb-threatening ischemia

Purpose: Although axillobifemoral bypass procedures have a lower mortality rate than aortobifemoral bypass procedures, they are limited by decreased patency, moderate hemodynamic improvement, and the need for general anesthesia. This report describes an alternative approach to bilateral aortoiliac occlusive disease using unilateral endovascular aortofemoral bypass procedures in combination with standard femorofemoral reconstructions.Methods: Seven patients who had bilateral critical ischemia and tissue necrosis in association with severe comorbid medical illnesses underwent implantation of unilateral aortofemoral endovascular grafts, which were inserted into predilated, recanalized iliac arteries. The proximal end of the endovascular graft was fixed to the distal aorta or common iliac artery with a Palmaz stent. The distal end of the graft was suture-anastomosed to the ipsilateral patent outflow vessel, and a femorofemoral bypass procedure was then performed.Results: All endovascular grafts were successfully inserted through five occluded and two diffusely stenotic iliac arteries under either local (1), epidural (5), or general anesthesia (1). The mean thigh pulse volume recording amplitudes increased from 9 ± 3 mm to 30 ± 7 mm and from 6 ± 2 mm to 26 ± 4 mm ipsilateral and contralateral to the aortofemoral graft insertion, respectively. In all cases the symptoms completely resolved. Procedural complications were limited to one local wound hematoma. No graft thromboses occurred during follow-up to 28 months (mean, 17 months).Conclusions: Endovascular iliac grafts in combination with standard femorofemoral bypass grafts may be an effective alternative to axillobifemoral bypass in high-risk patients who have diffuse aortoiliac occlusive disease, particularly when bilateral axillary-subclavian disease is present.

Aorto-iliac/femoral reconstructions in patients with vasculogenic impotence

One hundred and forty-eight patients out of 386 undergoing aorto-iliac or aortofemoral bypass had preoperative impotence, 37 of these were diabetics. In all of them Doppler studies revealed a penile/brachial pressure index less than 0.6 and an abnormal waveform analysis. Nocturnal penile tumescence was investigated in 44 cases and found to be abnormal. Angiography showed unilateral or bilateral obstructive lesions of the hypogastric arteries in 80%, in addition to aortic, common and external iliac and femoral lesions. One hundred and thirty patients (87.8%) had straight aorto-iliac/femoral bypass grafts inserted without a direct attempt to revascularise the hypogastric arteries but 24 had distal anastomoses to the bifurcation of the common iliac artery. In the remaining 18 patients the hypogastric artery was reconstructed on one side by an additional bypass or reimplantation on the graft. In 22 of 106 patients (20.7%) undergoing aortofemoral bypass, 18 of 24 (75%) with the distal anastomosis to the iliac bifurcation, and 14 of the 18 (77.7%) with revascularisation of the hypogastric arteries, erectile function was regained. A good result was obtained in only five of the diabetic patients (13.5%). Our experience suggests that: (1) impotence, as indicated by non-invasive investigations, was vasculogenic in origin since patients with the most effective revascularisation of the hypogastric arteries had the best results; (2) when it is feasible, revascularisation of the hypogastric arteries should be carried out more often, during the aorto-iliac or aortofemoral reconstructions, particularly in younger impotent patients; (3) aorto-iliac revascularisation restores potency in only a few diabetic patients.     

A novel technique of coronary revascularization in porcelain aorta: Report of two cases

Severe atherosclerosis of the distal ascending aorta increases the risk of intraoperative stroke during coronary artery bypass. More than one in situ arterial graft is required to avoid aortic manipulation during proximal anastomosis. The application of bilateral internal thoracic arteries is a good choice, but it also carries the risk of sternal wound complications. Using a composite graft constructed with a partially harvested in situ right internal thoracic artery graft and another vascular conduit prevents extreme ischemia of the sternum. This study describes the experience of successful coronary revascularization using bilateral internal thoracic arteries and modified with a composite graft in two patients with a severely atherosclerotic ascending aorta.     

Primary stent placement for late complete occlusion after aortoiliac reconstructive surgery: Report of a case

We report a case that was successfully treated by primary stent placement without thrombolysis or thrombectomy for graft thrombosis after aortoiliac reconstructive surgery. A 79-year-old man presented with a 2-month history of severe intermittent claudication of the right leg. He had undergone a surgical repair of abdominal aortic aneurysm with a bifurcated polyester graft 3 years before presentation. Digital subtraction angiography revealed total occlusion of the right limb of the graft. He underwent primary stent placement on the lesion, and completion angiography showed revascularization of the right limb. Primary stent placement can be performed to decrease the risks of surgery and increase the salvage of a graft with chronic total occlusion.
