Early results of external iliac artery stenting combined with common femoral artery endarterectomy

PURPOSE: The endovascular approach to external iliac artery (EIA) disease extending into the common femoral artery (CFA) has been avoided because of problems with stent placement across the inguinal ligament. Surgical treatment for this disease distribution includes extensive endarterectomy or bypass procedures or both. We report our initial experience with a combined open and endovascular approach to these patients. METHODS: We performed a retrospective analysis of all patients who underwent intraoperative EIA stenting after CFA endarterectomy/patch angioplasty between 1997 and 2000. Stents were positioned to end at the proximal endarterectomy endpoint, without crossing the inguinal ligament. Technical success, hemodynamic success, and clinical success were determined according to Society of Vascular Surgery/International Society of Cardiovascular Surgery criteria. Life-table analysis was performed for patency. RESULTS: Thirty-four patients (mean age, 68 years; 23 male, 11 female) had combined endovascular and open treatment of iliofemoral occlusive disease. Indications were claudication in 41% and critical limb ischemia in 59%. Femoral reconstruction included endarterectomy with patch angioplasty in all patients. EIA stent deployment incorporated the stenotic iliac segment and the proximal endpoint of the endarterectomy in all patients. Four patients (12%) also needed common iliac angioplasty at the same time for proximal iliac disease, and 14 patients (41%) also needed distal revascularization for associated femoropopliteal or tibial disease. Technical success and hemodynamic success were achieved in 100% of patients. Clinical success was achieved in 97% of patients. The mean postoperative increase in ankle-brachial index in patients with inflow procedures only was 0.36 (range, 0.1 to 0.85). The overall complication rate was 15%. With a mean follow-up period of 13 months (range, 0.5 to 28 months), 1-year primary patency and primary-assisted patency rates were 84% and 97%, respectively. No perioperative mortality was seen. CONCLUSION: EIA stenting as an adjunct to CFA endarterectomy/patch angioplasty allows for more localized surgery than conventional bypass. This approach also allows a better interface between the stent and endarterectomy than staged preoperative stenting. Technical success and early patency rates are excellent.     

PTA and stenting after previous aortoiliac endarterectomy.

OBJECTIVES: to evaluate the feasibility and long-term results of angioplasty and stenting in the treatment of restenosis following aortoiliac endarterectomy. MATERIALS AND METHODS: between 1991 and 1999 19 patients underwent angioplasty with selective stenting for recurrent stenosis after previous aortoiliac endarterectomy. Aortic lesions were treated five times in four patients. At the iliac level 28 lesions (25 stenosis and three occlusions) were treated in 16 patients (one patient had a stenosis at the aortic as well as iliac level). All patients were followed clinically and by ultrasound. In the second half of 1999, an angiogram or spiral CT-angiography was performed in all patients to determine long-term outcome. RESULTS: technical success was obtained in all patients and clinical success was achieved in 18 of the 19 patients. Angiographic cumulative primary patency for aortoiliac lesions was 96% at 1 year and 76% at 3 years. CONCLUSIONS: angioplasty with selective stenting of recurrent aortoiliac disease after previous aortoiliac endarterectomy is feasible and safe. Long-term clinical and angiographic patency rates are in accordance with results of aortoiliac angioplasty in general.     

Predicting outcome of angioplasty and selective stenting of multisegment iliac artery occlusive disease

BACKGROUND: Patients who require angioplasty and stenting of multiple iliac arterial segments often require reintervention to maintain long-term patency. Morphologic predictors and causes of failure are unknown. The purpose of the current study was to define arteriographic predictors of angioplasty and selective stent failure in the treatment of multisegment iliac occlusive disease. METHODS: All iliac segments (two common and two external) of 75 patients who underwent angioplasty and selective stent placement for multisegment iliac occlusive disease (>/= two segments) were scored through use of a modification of the Society of Cardiovascular and Interventional Radiology classification for iliac angioplasty (0 = no lesion; 4 = most severe). Total iliac score was calculated by summing scores from each segment. A separate external iliac score was calculated by adding only the external iliac scores. Arteriograms were reviewed initially and at the time of lesion recurrence and stratified by lesion location and previous intervention. RESULTS: The area of previous endovascular intervention was the site of recurrence in 75% of patients. New lesions, presumably a result of progressive atherosclerosis, occurred in 15% of patients, and lesions occurred in both new and previously treated iliac segments in 10% of patients. Only the external iliac score was an independent predictor of failed endovascular therapy despite reintervention. For patients with an external iliac score of 2 or less, the endovascular primary-assisted patency rates at 6, 12, and 24 months were 96%, 92%, and 89%, respectively. This was improved in comparison with the 90%, 63%, and 45% patency rates observed in patients with an external iliac score of 3 or more (P =.001). Patients with an external iliac score of 3 or more had a significantly lower incidence of hemodynamic and clinical improvement after intervention and a threefold higher need for surgical inflow procedures than patients with an external iliac score of 2 or less. CONCLUSIONS: Lesion formation after treatment of multisegment iliac occlusive disease typically occurs in areas of prior intervention. The extent of external iliac disease can be used to stratify patients with multisegment iliac occlusive disease who will likely respond to endovascular treatment with a durable result. Patients with extensive external iliac disease (score >/= 3) have poor results after angioplasty and selective stenting as applied in this study, even with endovascular reintervention. They are ideal subjects for prospective comparative studies of competing initial therapies, including stenting, endografting, and aortobifemoral bypass grafting.     

Endovascular management of iliac artery occlusions: extending treatment to TransAtlantic Inter-Society Consensus class C and D patients

OBJECTIVE: The preferential use of endovascular techniques to treat complex aortoiliac disease has increased in recent years. The purpose of this study was to review the outcomes and durability of recanalization, percutaneous transluminal angioplasty, and stenting for iliac occlusions based on the patient's TransAtlantic Inter-Society Consensus (TASC) stratification. METHODS: Between 1998 and 2004, more than 628 patients with a clinical diagnosis of aortoiliac atherosclerotic disease underwent arteriography. The endovascular treatment of 89 consecutive patients (mean age, 66 years; 58% male) with symptomatic iliac occlusions (TASC-B, -C, and -D) was the basis for this study. Original angiographic imaging was evaluated for lesion grade and runoff. Electronic and hard copy medical records were reviewed for demographic data, clinical variables, and noninvasive vascular laboratory testing. Kaplan-Meier estimators were used to determine patency rates according to Society for Vascular Surgery criteria. Univariate and multivariate analyses were performed. P values of <.05 were considered significant. RESULTS: Recanalization and percutaneous transluminal angioplasty/stenting (total, 178 stents) of occluded iliac arteries was technically successful in 84 (91%) of 92 procedures. Patients in the TASC-C and -D groups often required multiple access sites (50%) and femoral artery endarterectomy/patch angioplasty for diffuse disease (24%). The mean ankle-brachial index increased from 0.45 to 0.83. Distal embolization led to major amputation and eventual death in one patient. Two other deaths occurred in the perioperative period secondary to cardiorespiratory causes. Three-year primary patency, secondary patency, and limb salvage rates were 76%, 90%, and 97%, respectively, and progression of infrainguinal disease led to late limb loss in two patients. Diabetes as a risk factor was significantly associated with decreased primary patency (57% vs 83%; P = .049). Critical ischemia at presentation was associated with decreased patency rates as well (P = .002), but TASC classification did not significantly alter patency rates. CONCLUSIONS: Complex long-segment and bilateral iliac occlusions can be safely treated via endovascular means with high rates of symptom resolution. Initial technical success, low morbidity, and mid-term durability are comparable to results with open reconstruction. A liberal posture to open femoral artery reconstruction extends the ability to treat diffuse TASC-C and -D lesions via endovascular means.

Balloon-assisted remote external iliac artery endarterectomy: A safe and durable technique for the treatment of iliac artery occlusive disease

BackgroundHistorically, the treatment of iliac artery occlusive disease required a surgical bypass usually consisting of an aortobifemoral bypass or an iliofemoral bypass. With the advent of balloon angioplasty and stenting, these procedures are frequently replaced with endovascular options. However, the treatment of diffuse occlusive disease of the external iliac artery (EIA) using balloon angioplasty and/or stenting does not carry a favorable long-term patency rate. Remote endarterectomy of the EIA using ring dissectors with balloon assistance provides a novel, controlled, safe, and durable treatment of the diseased and/or occluded EIA.MethodsA retrospective review over the past 6 years was performed at our institution identifying patients treated with balloon-assisted remote endarterectomy of the EIA by the current five practicing vascular surgeons. The technique involves exposure of the ipsilateral common femoral artery. With nonocclusive disease, direct access into the common femoral artery is performed, a wire is traversed through the diseased EIA, and a balloon is inflated at the origin of the vessel providing hemostasis and control. A femoral endarterectomy is performed, and a ring dissector is passed over the endarterectomized material including the wire and balloon catheter and advanced remotely through the EIA up to the balloon. The balloon is briefly deflated, repositioned within the ring dissector, and reinflated, thus cutting the plaque. This allows for retraction of the inflated balloon and cutter, removing the endarterectomized core plaque. The procedure is similar for the treatment of an occluded EIA, but wire access across the occluded vessel is normally achieved with contralateral access. In both cases, the balloon provides control and hemostasis and is critically important in the rare treatment of vessel rupture.ResultsA total of 101 vessels were treated in 97 patients. The procedure was successful in 98 vessels (97%) with failure related to vessel rupture requiring conversion to an iliofemoral bypass. The estimated patency rate at three years was 94% with a median follow-up of 20 months. Restenosis/occlusion in four patients seemed to be related to a severe sclerotic response. The EIA was occluded 32% of the time. The common iliac artery (CIA) was diseased requiring angioplasty and stenting 29% of the time and a stent was placed at the transition zone between endarterectomized vessel and nontreated proximal most EIA or distal most CIA 58% of the time. There were no perioperative deaths.ConclusionsBalloon-assisted remote endarterectomy of the diffusely diseased and/or occluded EIA is a safe and durable option. It precludes the need for a prosthetic conduit and the risk of associated infection. It also involves a single groin incision and negates the need for retroperitoneal exposure of the CIA.     

Extraperitoneal endarterectomy for iliofemoral occlusive disease

Sixty patients with iliofemoral occlusive disease were treated by autogenous anatomic reconstruction by endarterectomy. Endarterectomy was performed extra-peritoneally by the eversion technique. The operative technique and its advantages and disadvantages are discussed. Six patients had postoperative complications of acute anastomotic hemorrhage (two patients), would hematoma (two patients), and atelectasis (two patients). Sixty patients discharged with patient arterial reconstruction were followed up from 5 months to 17 1/2 years, with a mean follow-up of 53 months. There were no other vascular complications. Seventy limbs were at risk during this period, with an accumulative patency rate of 80.4% at 5 years and 71.4% at 10 years. There were 11 occlusions of the external iliac artery and one stenosis of the common femoral artery. Failures occurred mainly in the external iliac artery, which appears to be the limiting factor in the continued patency of endarterectomy. There were 18 deaths (30%). Nine deaths were attributed to the complications of arteriosclerosis.

Retrograde iliofemoral endarterectomy facilitated by balloon angioplasty

Purpose: The purpose of this study was to explore the feasibility of iliofemoral endarterectomy performed through a single groin incision.Methods: Thirty-two patients aged 34 to 75 years (mean age 63.4 years) with a male/female ratio of 20:12 underwent 36 lower extremity inflow reconstructions from July 1989 to September 1994. Surgical indications were for limb-threatening ischemia in 24 patients and for claudication in eight patients. The procedures were done for occlusive disease of the external iliac artery and common femoral artery with patients under either spinal (n = 24) or local (n = 12) anesthesia. Intraoperative balloon angioplasty with fluoroscopic guidance preceded open retrograde iliofemoral endarterectomy. Adjunctive procedures included 18 profundaplasties, eight femorofemoral, nine femoropopliteal, and one femorotibial bypasses.Results: Thirty-three of the 36 cases were initially successful. The three failures were in patients with extensive calcification. The mean follow-up has been 36.4 months, and the patency rate was 80.5% at 3 and 4 years. The four failures noted on follow-up were caused by three common iliac artery stenoses and one iliac system occlusion. The former group was successfully treated with balloon angioplasty/stent, and the latter patient required an aortofemoral bypass. No operative deaths or limb loss occurred in this series.Conclusions: Retrograde iliofemoral endarterectomy facilitated by balloon angioplasty is a safe, easy-to-perform, and viable option for patients with combined external iliac artery and common femoral artery occlusive disease. Midterm results (36.4 months) are favorable, and most hemodynamic failures are easy to correct with standard endovascular techniques. (J VASC SURG 1995;22:742-50.)
