Abstract
PURPOSE To describe the off-label use of tapered iliac limbs for the treatment of isolated iliac aneurysms with proximal landing zone significantly larger than distal landing zone. TECHNIQUE Inversion of a Gore Excluder tapered leg (W. L. Gore & Associates Inc, Flagstaff, Arizona) with a modified upside-down technique is described. The endoprosthesis, with the olive at the tip of the releasing system previously cut, is inserted in a tip-to-tip fashion into a 15 Fr introducer sheath. The graft is released inside the introducer. An 18 Fr introducer sheath is advanced up to the proximal sealing zone. Following the removal of the 18 Fr dilator, the 15 Fr introducer with the pre-released graft is inserted co-axially into the 18 Fr introducer. A pre-cut 15 Fr dilator is brought up to the endograft and used as a pusher. A pull-back maneuver of the co-axial system, countertractioning with the dilator maintained in position, allows the delivery of the endograft. CONCLUSION This technique might offer a feasible option in case of endovascular exclusion of isolated iliac artery aneurysms with significant landing zone diameter mismatch. Extracorporeal inversion is time-saving and could be safer in terms of graft damage and infection.

Abstract
Isolated aneurysms of the iliac arteries are rare. The diagnoses of these aneurysms become easier with non-invasive radiologic investigations. The development of endovascular treatment is a recent alternative to surgical treatment. We report our experience in the management of 8 cases of isolated iliac aneurysms in the department of cardiovascular and thoracic surgery of the Habib Bourguiba Hospital of Sfax.

Abstract
We retrospectively reviewed 41 patients with isolated iliac artery aneurysms presenting over a 21-year period. The mean age was 72 years. Mean aneurysmal diameter was 6.0 cm (range, 3.2–13 cm). The aneurysms were located in the common iliac artery in 31 patients, internal iliac artery in 7, and both arteries in 3. Rupture occurred in 20 patients (49%). The frequency of rupture of isolated iliac artery aneurysms was significantly higher than that of abdominal aortic aneurysms (8%) during the same period. The 30-day mortality was 9.8%; death in all 4 patients was due to rupture of the aneurysm. The surgical procedure was aneurysmectomy and replacement with a bifurcated prosthetic graft in 24 patients (59%), closure of the common iliac artery with a femorofemoral crossover in 7, minilaparotomy in 3, thromboexclusion in 6, and endoluminal stent-graft repair in one. In contrast to abdominal aortic aneurysms, isolated iliac artery aneurysms can be treated by various methods other than replacement with a bifurcated prosthetic graft. When selecting a strategy for such aneurysms, it is important to choose an approach appropriate to the location and risk, because of the frequency of rupture.

Abstract
Isolated aneurysms of the iliac arteries are relatively rare conditions that traditionally have been treated by surgical reconstruction. We report our experience with endovascular treatment of iliac artery aneurysms (IAAs) with Anaconda stent graft limb. Two male patients were found to have 4.5 and 3.6 cm isolated common IAAs, respectively. The endograft was successfully advanced and deployed precisely to the intended position in both cases. In one case the internal iliac artery was embolized. No type I or II endoleak was observed immediately after the procedure. In one patient postimplantation fever (>38°C) and gluteal claudication occurred. After 2 years followup both iliac endovascular stent grafts are patent and without endoleak. Endovascular treatment with Anaconda limb stent graft seems to be a safe and feasible alternative to open surgery.

Abstract
We describe a previously unreported case of abscess formation around the right internal iliac artery (IIA) after coil embolization prior to endovascular aneurysm repair (EVAR). A 75-year-old man was admitted for elective repair of a right common iliac aneurysm. The right IIA coil embolization and EVAR procedures were uncomplicated and assessment by postoperative computed tomography (CT) was satisfactory. The patient was readmitted 2 weeks after EVAR with right buttock pain and pyrexia. CT indicated an isolated abscess around the coil-embolized IIA. The patient was successfully treated with CT-guided percutaneous drainage.

Abstract
We report our experience and the midterm results of a modern technique for endovascular management of isolated iliac artery aneurysms (IAAs) with unfavorable neck anatomy, which involves the inversion of an iliac leg of a Zenith stent graft. Patients who underwent endovascular IAA repair from 2002 to 2010 were reviewed. A total of 12 patients, with a mean age of 77.6 years, underwent endovascular repair of 13 IAAs. Mean size of the aneurysms was 54.6 mm (range 34-133 mm). Mean proximal neck diameter was 18 mm (range 15-22 mm). In 7 patients, the length of the proximal neck was <15 mm (10-14 mm). Only 1 patient developed thrombosis of the stent graft immediately after the operation. Patients were followed up for a mean of 31.5 months (range 18-72 months). Our midterm results demonstrate the durability of this technique in the management of iliac aneurysms with unfavorable anatomy.

Abstract
The objective of this study was to identify factors predicting the need for reintervention after endovascular repair of isolated iliac artery aneurysm (IIAA). We reviewed prospectively collected database records of all patients who underwent endovascular repair of IIAA between 1999 and 2008. Detailed assessment of the aneurysms was performed using computed tomography angiography (CTA). Follow-up protocol included CTA at 3 months. If this showed no complication, then annual duplex scan was arranged. Multivariate analysis and analysis of patient survival and freedom from reintervention were performed using Kaplan-Meier life tables. Forty IIAAs (median diameter 44 mm) in 38 patients were treated (all men; median age 75 years), and median follow-up was 27 months. Endovascular repair of IIAA was required in 14 of 40 aneurysms (35%). The rate of type I endoleak was significantly higher with proximal landing zone (PLZ) diameter >30 mm in the aorta or >24 mm in the common iliac artery or distal landing zone (DLZ) diameter >24 mm (P = 0.03, 0.03, and 0.0014, respectively). Reintervention rate (RR) increased significantly with increased diameter or decreased length of PLZ; increased DLZ diameter; and endovascular IIAA repair (P = 0.005, 0.005, 0.02, and 0.02 respectively); however, RR was not significantly affected by length of PLZ or DLZ. Freedom-from-reintervention was 97, 93, and 86% at 12, 24, and 108 months. There was no in-hospital or aneurysm-related mortality. Endovascular IIAA repair is a safe treatment option. Proper patient selection is essential to decrease the RR.

Abstract
The purpose of this article is to report the feasibility and preliminary results of the treatment of isolated iliac artery aneurysms (IAAs) with Anaconda limbs (Vascutek Ltd., Inchinnan, Renfrewshire, Scotland). A prospective cohort is reported of consecutive IAAs treated by two senior surgeons from May to December 2006. One or more Anaconda limbs were used, and internal iliac arteries were embolized if necessary. Twelve IAAs in 11 patients were treated. The average IAA diameter was 4.3 ± 1.1 cm, and the average diameter of stent used was 14 ± 2.5 mm, with an average total length of 97 ± 25 mm. At a mean follow-up of 12 ± 4 months, there were no graft-related complications, graft occlusions, or requirements for reintervention. Endovascular treatment for isolated IAAs under local anesthesia using Anaconda limbs is feasible, safe, and effective. However, as with all new technology, longer follow-up data are necessary.

Abstract
Open iliac aneurysm repair has been historically associated with major morbidity and mortality. The introduction of endovascular devices and techniques has expanded the armamentarium available to treat these aneurysms, and several methods have been reported. However, the off-label use of a commercially available, flared extension limb stent-graft to treat a common iliac artery aneurysm (CIA) by preliminary extracorporeal predeployment, endograft reversal, and reinsertion into the delivery sheath to fashion a tapered endograft has not been previously reported. A case report of a CIA aneurysm diagnosed 9 years after transperitoneal tube graft abdominal aortic aneurysm repair treated with ipsilateral hypogastric artery occlusion with an Amplatzer plug and placement of a reversed, tapered extension limb stent-graft is herein presented.

Abstract
BACKGROUND To compare outcomes following endovascular repair in abdominal aortic aneurysm (AAA) patients with and without concomitant iliac artery aneurysm disease. METHODS Data on patient characteristics and risk factors, aneurysm morphology, interventional details, complications, and mortality were retrieved from the EUROSTAR registry database for the period from October 1996 to November 2006. AAA patients without concomitant iliac aneurysm disease (group I, n = 6286) were compared to 1268 patients with aneurysmal iliac vessels (group II) regarding mortality, device-related complications, and need for secondary interventions. Logistic regression and Cox proportional hazards model were performed to assess independent associations with outcome parameters in the study groups. RESULTS Group II had more patients classified as ASA III or IV (55.1% versus 50.3% in group I; p = 0.002); they were more frequently unfit for open aortic repair (30.3% versus 23.4%; p<0.0001) and had larger-diameter aneurysms (62.3 versus 60.7 mm; p<0.0001) and infrarenal necks (24.5 versus 24.1 mm; p<0.001). In addition, group II patients had a higher rate of internal iliac artery occlusion (11.4% versus 5.2%; p<0.0001) and more significant angulation of the aortic neck (30.8% versus 24.3%; p<0.0001) and iliac artery (48.3% versus 41.9%; p<0.0001). Group II patients had higher 5-year cumulative incidences of distal type I endoleaks (9.1% versus 4.3%; p<0.0001), iliac limb occlusion (5.9% versus 4.4%; p = 0.040), secondary transfemoral intervention (17.6% versus 8.9%; p = 0.019), and aneurysm rupture (4.5% versus 1.7%; p = 0.042). CONCLUSION Although aneurysm-related mortality and mortality from other causes were similar in both study groups, concomitant iliac artery aneurysms in AAA patients were associated with an increased incidence of distal type I endoleak, iliac limb occlusion, and aneurysm rupture. Therefore, caution is warranted, and efforts should be made to avoid procedural mishaps.

Abstract
Although relatively uncommon, isolated iliac artery aneurysms are associated with significant risk of rupture and death. Clinical presentation can be confusing and ultrasound or CT imaging is paramount in establishing the diagnosis and anatomical extent of disease. Important considerations prior to intervention include determination of proximal neck, involvement of the internal iliac artery, and status of the contralateral internal iliac artery. Endovascular repair has evolved as the first choice treatment option for patients with anatomically suitable iliac artery aneurysms. In uncommon circumstances when endovascular treatment may result in significant pelvic ischemia or the primary symptoms are related to extrinsic compression of adjacent structures, surgical repair may be the preferred option.

Abstract
Open surgical repair of iliac aneurysms has been usually associated with significant morbidity and mortality. The introduction of novel endovascular techniques has expanded the currently available options to treat these aneurysms. However, the use of endoluminal stent grafts to treat common iliac artery aneurysms by landing their distal end into the hypogastric artery in patients where flow into the latter artery is crucial to avoid end-organ ischemia has only been rarely reported in the past. A case report of a common iliac aneurysm case treated with a novel therapeutic approach, not previously reported is herein presented. Three telescopically-overlapping Hemobahn/Viabahn polytetrafluoroethylene (PTFE)-covered endoprosthesis (W.L. Gore & Associates, Flagstaff, AZ) were used with success.

Abstract
PURPOSE To report about the endovascular treatment of isolated iliac artery aneurysms (IIAA) with stentgraft placement and transluminal or CT-guided embolization of the internal iliac artery or the combination of these methods. METHODS AND MATERIALS Over a period of 5.6 years, 36 interventions were performed in 20 patients with 23 IIAAs. In a retrospective analysis patient records were reviewed. The CT-angiography follow-up was evaluated for the presence of re-perfusion of the IIAA and for change of aneurysm diameter. RESULTS Primary success was achieved in 15/23 aneurysms (65%), and secondary success in 21/23 aneurysms (91%). In 5/23 cases two interventions and in 1/23 cases three interventions were necessary to achieve secondary success. Embolization alone, as a therapy for aneurysms involving only the internal iliac artery, had a success rate of 27%. No procedure-related minor or major complications occurred. Mean decrease of aneurysm size during a mean observation period of 14.1 months was 6.9% which was not significant (p=0.3; 95% confidence interval +7-21%). CONCLUSION Endovascular therapy of isolated iliac artery aneurysms performed percutaneously has become a treatment alternative to open surgical repair. This method is feasible and safe with low procedure-related morbidity and mortality. However, on average more than one intervention has to be performed to achieve successful permanent exclusion of the aneurysm and embolization alone in isolated internal iliac artery aneurysms is not sufficient.

Abstract
PURPOSE The aim of this study was to assess the effectiveness of endovascular treatment of isolated iliac artery aneurysms (IAAs). MATERIALS AND METHODS Between March 1999 and March 2004, 15 isolated IAAs in 13 patients (mean age: 71.8 years) were selected for endovascular repair by means of a covered stent or stent-graft: 12 were in the common iliac artery (2 with the proximal end 12 mm from the aortic bifurcation and 2 involving the distal hypogastric artery), and three were in the external iliac artery. The preoperative study and the follow-up (at 3, 6 and 12 months and yearly thereafter) were performed by computed tomography (CT) angiography. RESULTS Primary technical success was obtained in all cases, without periprocedural complications. Two patients died within 3 months and were not considered for follow-up. Follow-up (mean duration: 25 months, range: 6-60 months) in the remaining 11 patients, affected by 13 aneurysms, showed aneurysm exclusion in nine cases and progressive shrinkage of the aneurysmal sac in four cases, whereas in the other five, the size of the aneurysm remained unchanged. In a patient with bilateral IAA, bilateral proximal endoleaks were observed after 2 years, and the patient was treated with a bifurcated aortic stent-graft. In another patient with a large aneurysm, a left aortofemoral bypass became necessary after 2 months because of stent-graft dislodgement. In another patient, an endoleak from the hypogastric artery occurred after 2 years but was not treated. CONCLUSIONS Endovascular treatment of isolated IAA is a feasible procedure that is less invasive than surgery and yields excellent short-and midterm results. However, a longer follow-up and larger patient series are needed to verify the long-term efficacy of this form of treatment.

Abstract
BACKGROUND Isolated aneurysms of the iliac arteries are uncommon. Previously treated by conventional surgery, there is increasing use of endografts to treat these lesions. PURPOSE The purpose of this study was to assess the efficacy, safety, and durability of the stent-grafts for treatment of iliac artery aneurysms (IAAs). The results of endografting for isolated IAAs over a 10-year period were analyzed retrospectively. The treatment methods differed depending on the anatomic location of the aneurysms. Twenty-one patients (1 woman, 20 men) underwent endovascular stent-graft repair, with one procedure carried out under emergency conditions after acute rupture. The mean aneurysm diameter was 4.6 cm. RESULTS The procedural technical success was 100%. There was zero 30-day mortality. Follow-up was by interval CT scans. At a mean follow-up of 51.2 months, the stent-graft patency rate was 100%. Reintervention was performed in four patients (19%): one patient (4.7%) with a type I endoleak and three patients (14.3%) with type II endoleaks. CONCLUSION We conclude that endovascular repair of isolated IAAs is a safe, minimally invasive technique with low morbidity rates. Follow-up results up to 10 years suggest that this approach is durable and should be regarded as a first treatment option for appropriate candidates.

Abstract
OBJECTIVE To present our initial experience with the Zenith bifurcated iliac side branch device that preserves internal iliac artery flow whilst excluding aorto-iliac aneurysms. METHODS Between November 2005 and October 2006, data was prospectively collected on 8 patients in whom this device was used; 2 aorto-bi-iliac aneurysms, 3 aorto-uni-iliac aneurysms, 1 solitary common iliac aneurysm, 1 distal type 1 endoleak, and 1 internal iliac aneurysm. RESULTS No mortality or major complications resulted from use of this device. The median fluoroscopy time was 53 minutes (range 38 to 105) and a median of 102 g of iodine (range 84 to 130) as contrast were used. One patient required a blood transfusion and only one of the eight side branches occluded. There has been no endoleak related to the device in the median follow-up period of 6 months (1 to 14 months). CONCLUSION This device provides an alternative for the management of patients with aorto-iliac aneurysms that is safe and less complex than, previously described, hybrid procedures that preserve internal iliac flow.

Abstract
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.

Abstract
In comparison to endovascular repair of fusiform iliac aneurysms, endovascular repair of large iliac anastomotic aneurysms can be difficult because of their saccular nature and redundancy of the iliac limb of the prosthetic graft. Iliac anastomotic aneurysms may have patency of ipsilateral hypogastric artery branches necessitating coil embolization. We report technical challenges incurred in two patients during endovascular repair of large symptomatic iliac anastomotic aneurysms.

Abstract
OBJECTIVE We reviewed our experience with endovascular treatment of isolated iliac artery aneurysms (IAAs). METHODS Medical records for consecutive patients undergoing endovascular IAA repair from 1995 to 2004 were reviewed. Computed tomography (CT) angiograms were used to assess IAA location, size, and presence of endoleaks after endovascular repair. Rates of primary patency and freedom from secondary interventions were estimated using the Kaplan-Meier life-table method. RESULTS From July 1995 to November 2004, 45 patients (42 men), with a mean age of 75 years, underwent endovascular repair of 61 isolated IAAs: 41 common iliac, 19 internal iliac, and one external iliac. Five patients (11%) were symptomatic, although none presented with acute rupture. The mean preoperative IAA diameter was 4.2 +/- 1.7 cm. Fifteen patients (33%) had prior open abdominal aortic aneurysm repair. Local or regional anesthesia was used in 28 cases (62%). Thirty-four patients (75%) were treated with unilateral iliac stent-grafts, eight (18%) with bifurcated aortic stent-grafts, and three (7%) with coil embolization alone. Perioperative major complications included one early graft thrombosis that eventually required conversion to open repair and one groin hematoma that required operative evacuation. On follow-up, late complications included one additional graft thrombosis and one late death after amputation. No late ruptures occurred after endovascular repair, with a mean follow-up of 22 months (range, 0 to 60 months). The mean postoperative length of stay was 1.3 +/- 1.0 days. On postoperative CT scans obtained at 1, 6, 12, 24, and 36 months, aneurysm shrinkage was noted in 18%, 29%, 57%, 67%, and 83% of IAAs, respectively, compared with the baseline diameter. One hypogastric aneurysm enlarged in the presence of a later identified type II endoleak. Five endoleaks were noted (4 type II, 1 indeterminate) at 1 month, with four other endoleaks (1 type II, 1 type III, 2 indeterminate) identified on later CT scans. At 2 years, primary patency was 95%, and freedom from secondary interventions was 88%. CONCLUSIONS Endovascular repair of isolated IAAs appears safe and effective, with initial results similar to those after endovascular abdominal aortic aneurysm repair.

Abstract
OBJETIVO: La cirugía endovascular se ha establecido como una opción eficaz en el tratamiento de la enfermedad oclusiva ateroesclerótica de las arterias iliacas. Sin embargo, el uso de estos procedimientos para tratar otro tipo de lesiones aún no ha sido bien estudiado. Nuestro objetivo es analizar indicaciones y resultados del uso de endoprótesis en lesiones iliacas no oclusivas. MATERIAL Y MÉTODOS: Revisamos retrospectivamente los registros de 14 pacientes consecutivos, todos hombres, 61,6 años de edad en promedio (rango: 25-80) tratados por vía endovascular entre 2001 y 2006 por lesiones iliacas no oclusivas. El estudio pre y postoperatorio incluyó tomografía computada. El procedimiento se efectuó en quirófano, utilizando un angiógrafo digital. Se usó acceso femoral insertando endoprótesis tubulares. RESULTADOS: En 11 pacientes se asoció embolización de arteria hipogástrica ipsilateral. Las patologías tratadas fueron: ocho aneurismas ateroescleróticos, 3 disecciones, 2 lesiones traumáticas y un pseudoaneurisma anastomótico. La co-morbilidad más frecuente fue la hipertensión en 43% de los casos. No hubo mortalidad operatoria. Un paciente presentó un pseudoaneurisma femoral tratado con compresión. Un paciente tratado por fístula arteriovenosa traumática a nivel iliaco resuelve su insuficiencia cardiaca, con persistencia asintomática de mínimo flujo. La estadía postoperatoria fue de 3 días (mediana). No se presentaron otras endofugas iniciales o tardías. Durante un seguimiento promedio de 20,5 meses (rango 1 a 49), un paciente fallece por cáncer y ninguno ha requerido procedimientos complementarios. CONCLUSIÓN: El tratamiento endovascular de lesiones iliacas mediante endoprótesis es seguro y permite un resultado durable en el manejo de un amplio espectro de patologías.

Abstract
INTRODUCTION Endograft limb extension to the external iliac artery with embolization of an internal iliac artery (IIA) may be necessary in patients with abdominal aortic aneurysms (AAAs) extending to the common iliac artery to prevent endoleak during endovascular aortic aneurysm repair (EVAR). Coil embolization of the IIA can be performed at the same operative setting as EVAR or, alternatively, as a staged procedure. Most interventionalists favor the latter approach to avoid excessive contrast material and prolonged operative time. We investigated the clinical outcome of concomitant vs staged unilateral IIA embolization in the setting of EVAR. METHODS Vascular surgeons at our institution treated 24 patients with infrarenal EVAR and unilateral coil embolization of the IIA from October 1, 2000 to June 30, 2005. All patients had normal renal function. The details of the operative procedure and perioperative complications were compared in patients undergoing concomitant vs staged procedures. Follow up was 1 to 40 months (average, 11 months). RESULTS Among the 24, 16 underwent concomitant unilateral IIA embolization in the setting of EVAR and eight patients underwent the staged procedure. Average duration of operative time (298 vs 284 minutes), amount of intravenous contrast (215 mL vs 164 mL), and preoperative (1.12 vs 1.26 mg/dL), and postoperative (1.15 v. 1.31 mg/dl) creatinine levels were similar in the concomitant vs staged group, respectively (P > .05 for all factors). More sensitive markers of renal insufficiency such as creatinine clearance were not measured. In the concomitant group, 25% (4/16) of patients reported significant symptoms of buttock claudication ipsilateral to the embolized IIA, which resolved after a mean of 8.8 months (range, 1 to 15 months) vs no cases (0/8) in the staged group (P = .02048). One patient in the staged group developed ischemic colitis, which was treated conservatively. Coil embolizations that were performed as staged procedures were all done on an outpatient basis. All 24 patients were admitted the day of the EVAR and were discharged the next day, except one patient in the concomitant group was discharged the second day after the procedure, and one patient in the staged group was discharged 7 days after the procedure. CONCLUSION Despite concern of prolonged operative time and the amount of contrast needed to perform concomitant IIA embolization and EVAR, our results showed that in patients with normal renal function, concomitant unilateral IIA embolization in the setting of EVAR was safe and effective and associated with shorter hospitalization compared with staged procedures. The disadvantage of a concomitant procedure is an increased likelihood of transient buttock claudication, but the small number of patients in this series prohibits definite conclusions about this complication. The concomitant procedure may be preferable for infirm patients with normal renal function who would be greatly inconvenienced by two procedures.

Abstract
OBJECTIVE To report the mid term results of a prospective cohort of iliac artery aneurysms (IAAs) treated with endovascular tubular stent-grafts. METHODS All IAAs referred to the University Medical Center Groningen between June 1998 and June 2005 were evaluated for endovascular repair. Criteria for repair were a diameter of > or = 30 mm for anastomotic aneurysms and > or = 35 mm for true aneurysms. Preferentially, tubular grafts were used. Follow-up included both radiographs of the abdomen and duplex examination. RESULTS In 35 patients, 40 IAAs were treated endovascularly with a tubular stent-graft. Elective repair was performed in 30 patients (86%) and emergent repair in five patients (14%). Aneurysms were false in 26 cases (65%) and true in 14 cases (35%). Local anesthesia was used in 74% of the cases. The stent-grafts that were used included the Excluder contralateral limb (n = 28, 70%), Passager (n = 9, 22.5%), Hemobahn (n = 2, 5%), and Wallgraft (n = 1, 2.5%). The mean operation time was 83 +/- 28 minutes (range, 50 to 150 minutes). Mean hospital stay was 3.3 +/- 2.3 days (range, 1 to 12 days). There was no 30-day mortality. Patients were followed up for a mean of 31.2 +/- 20.7 months (range, 3 to 83 months). Complications occurred in two patients during follow-up, including migration with a proximal type I endoleak in one, and occlusion of the stent-graft in the other. The internal iliac artery was intentionally sacrificed in 28 patients (70%), and this led to gluteal claudication in three patients. CONCLUSION Endovascular repair of iliac artery aneurysms with flexible stent-grafts is a minimally invasive technique and is associated with low mortality and morbidity. Follow-up results up to 5 years suggest that the technique is durable. It should be regarded as a first choice treatment option for suitable aneurysms.

Abstract
OBJECTIVE The purpose of this study was to assess the pelvic circulation during endovascular abdominal aortic aneurysm repair (EVAR) with a new monitoring system measuring penile and buttock blood flow. METHODS We measured penile brachial pressure index (PBI) during EVAR by pulse-volume-plethysmography (form PWV/ABItrade mark). We also measured bilateral gluteal tissue oxygen metabolism with near-infrared spectroscopy to provide a gluteal tissue oxygenation index (TOI). Twenty-two men who underwent aortouni-iliac stentgraft with crossover bypass for exclusion of abdominal aortic aneurysm were studied. Twelve patients underwent aorto-uni-common iliac artery stentgraft (CIA) and ten underwent aorto-uni-external iliac artery stentgraft (EIA). RESULTS In all patients, there was an immediate reduction in PBI during the EVAR procedure. After revascularization of the ipsilateral limb of the stent graft, the recovery of PBI was significantly less in EIA group. After the completion of crossover bypass, PBI in both groups recovered to the baseline values. In both groups there was a bilateral reduction in gluteal TOI during malperfusion of the internal iliac artery. After revascularization of ipsilateral limb of the stent graft, the ipsilateral TOI recovered to the baseline level in CIA patients, but recovery was incomplete in EIA patients. In contrast, contra-lateral TOI remained low in both groups after revascularization of ipsilateral limb of the stent graft. Only after completion of crossover bypass did the contra-lateral TOI recover to baseline level in both groups. CONCLUSIONS Both TOI at the buttocks and PBI are a sensitive reflection of pelvic haemodynamics. Penile blood flow and bilateral gluteal blood flow are supplied via different circulations and both should be monitored for full assessment of the pelvic circulation.

METHODS Between August and December 2004, in preparation for endograft repairs of aortoiliac or common iliac artery aneurysms, or both, at a community hospital system, five patients underwent the occlusion of the internal iliac artery with an Amplatzer Vascular Plug to prevent endoleak. During the preceding 12 months, the conventional coil embolization of the internal iliac artery was used for the same purpose in 10 patients. RESULTS In five patients undergoing the Amplatzer Vascular Plug occlusion of the internal iliac artery, precise deployment at the origin of the artery was achieved. Complete and precise occlusion was confirmed angiographically, and only one device was used for each internal iliac artery. Two patients reported mild buttock claudication 2 weeks after occlusion, which resolved completely by 6 and 8 weeks, respectively. A type II endoleak from the inferior mesenteric artery developed in one patient. In the previous 10 patients, 11 internal iliac arteries were treated with conventional coils. Subsequent repeat coil embolization was required for three patients. The procedural complications in this second group included one case of coil embolization into the superficial femoral artery and one into the common iliac artery; both errant coils were retrieved successfully by endovascular techniques. An average of 7 +/- 3.4 (mode of 5) coils were used for each internal iliac artery. Three cases of buttock claudication occurred after the unilateral internal iliac artery occlusion in this group and did not resolve. No evidence of ischemic bowel, buttock necrosis, or sexual dysfunction was observed in either group. The estimated average cost to occlude one internal iliac artery was 375 dollars for Amplatzer Vascular Plugs and 3,500 dollars for conventional coils. CONCLUSIONS The Amplatzer Vascular Plug allows for a cost-effective method to occlude the internal iliac artery in patients undergoing endograft repairs of aortoiliac aneurysms. The use of a single device with a precise placement at the origin of the artery minimizes cost and avoids ischemic complications.

Abstract
Transcatheter embolization of hypogastric artery aneurysms has become an attractive therapeutic alternative for many patients with this difficult lesion. Because of the increasing use of stent grafting for treatment of abdominal aortic aneurysms, transcatheter embolization of normal-caliber hypogastric arteries has become an almost routine procedure, usually accomplished with little morbidity. Applying this treatment to aneurysmal hypogastric arteries, however, involves greater technical complexity and a significantly higher risk of ischemic complications. We present three cases to illustrate the technical challenges of hypogastric aneurysm embolization, the potentially devastating ischemic complications, and the clinical situations that may predispose to poor outcomes.

Abstract
OBJECTIVE This study was carried out to compare the functional outcomes after hypogastric artery bypass and coil embolization for management of common iliac artery aneurysms in the endovascular repair of aortoiliac aneurysms (EVAR). METHODS Between 1996 and 2002, 265 patients underwent elective or emergent EVAR. Data were retrospectively reviewed for 21 (8%) patients with iliac artery aneurysms 25 mm or larger that involved the iliac bifurcation. Patients underwent hypogastric artery bypass (n = 9) or coil embolization (n = 12). Interviews about past and current levels of activity were conducted. A disability score (DS) was quantitatively graded on a discrete scale ranging from 0 to 10, corresponding to "virtually bed-bound" to exercise tolerance "greater than a mile." Worsening or improvement of symptoms was expressed as a difference in DS between two time points (-, worsening; +, improvement). RESULTS There was no difference in age (72.6 +/- 7.3 years vs 73.1 +/- 6.4 years), sex (male-female ratio, 8:1 vs 11:1), abdominal aortic aneurysm size (60.1 +/- 5.9 mm vs 59.3 +/- 7.0 mm), or number of preoperative comorbid conditions (1.9 +/- 0.8 vs 2.1 +/- 0.8) between hypogastric bypass and coil embolization groups, respectively. Mean follow-up was shorter after hypogastric bypass (14.8 vs 20.5 months; P <.05). There was no difference in the mean overall baseline DS between the bypass and the embolization groups (8.0 vs 7.8). Six (50%) of the 12 patients with coil embolization reported symptoms of buttock claudication ipsilateral to the occluded hypogastric artery. No symptoms of buttock claudication were reported after hypogastric bypass (P <.05). There was a decrease in the DS after both procedures; however, coil embolization was associated with a significantly worse DS compared with hypogastric artery bypass (4.5 vs 7.3; P <.001). In 4 (67%) of 6 patients with claudication after coil embolization symptoms improved, with a DS of 5.4 at last follow-up. This was significantly worse than in patients undergoing hypogastric artery bypass, with a DS of 7.8 at last follow-up (P <.001). There was no difference between the groups in duration of procedure, blood loss, length of hospital stay, morbidity, or mortality (0%). CONCLUSIONS Hypogastric artery bypass to preserve pelvic circulation is safe, and significantly decreases the risk for buttock claudication. Preservation of pelvic circulation results in significant improvement in the ambulatory status of patients with common iliac artery aneurysms, compared with coil embolization.

Abstract
Isolated iliac artery aneurysms are rare but dangerous aneurysms associated with a high incidence of rupture (between 14 and 70%). Rupture is frequently associated with an exceedingly high mortality primarily because of the elusive nature of the presenting symptoms and the resulting major delays in treatment. Accordingly these aneurysms are best managed aggressively. Although emerging endovascular techniques show promise surgical resection and reconstruction remains the gold standard for definitive management and has withstood the test of time with excellent durable and unparalleled results. That said, from an operative perspective these aneurysms are technically demanding and remain one of the more formidable technical challenges in vascular surgery. To highlight the key elements involved in a successful repair we present a right internal iliac artery aneurysm with an associated contralateral common iliac artery occlusion, review the necessary preoperative planning and the available surgical treatment options, and detail the technical steps leading to a successful reconstruction. Careful operative planning is critical. Inadequate preoperative studies, inadequate preoperative decision making, and a poorly formulated operative strategy can lead to catastrophic results. Some of the most feared complications include pelvic venous injury with resulting massive hemorrhage and postoperative pelvic ischemia (with resulting rectal and/or spinal cord ischemia) which occurs as a result of inadequate contralateral collateral pelvic blood flow when the internal iliac artery is not reimplanted. Accordingly the preoperative workup must include a careful analysis of the adequacy of the contralateral pelvic blood flow to supply collateral flow in the event that the internal iliac is not reimplanted. In the presence of compromised contralateral internal iliac perfusion, resection and reconstruction or an alternative form of pelvic revascularization is mandatory. Excellent and unencumbered exposure is mandatory for a safe and successful repair. The retroperitoneal approach as illustrated in this case is strongly recommended. Although it is challenging excellent results can be achieved by resection of the aneurysm and reconstruction.

Abstract
Endovascular techniques including angioplasty, stenting, and endoluminal stent grafts represent important therapeutic options for the treatment of vascular disease. Technologic advances have allowed for the treatment of aneurysmal disease as well as extra-cranial carotid disease that previously required surgical methods. The success of various endovascular therapies varies based on anatomic location and extent of disease. The clinical results in different arterial segments are increasingly recognized in the published literature. The aortoiliac arterial bed appears to respond most favorably, with less favorable results observed in the infra-inguinal and infrapopliteal locations. There is increasing evidence that stent-supported carotid angioplasty using cerebral protection will play an important future role in the treatment of carotid artery stenosis. Less invasive techniques to treat abdominal aortic aneurysms with endoluminal stent grafts have dramatically changed the available therapeutic options. Improved devices and delivery systems will likely increase the number of patients who can be successfully treated in this manner. The evolution of endovascular therapies will continue to change the way we treat vascular disease.

Abstract
PURPOSE To demonstrate the feasibility of a hybrid endovascular procedure to preserve blood flow in the internal iliac arteries (IIA) during aortoiliac endografting. TECHNIQUE When aneurysmal dilatation makes the distal neck in the common iliac artery (CIA) too short for an adequate seal, the CIA bifurcation is exposed via an extraperitoneal approach after endograft deployment. Via an arteriotomy in the CIA, the distal end of the stent-graft is sutured to the CIA bifurcation under direct vision to preserve IIA blood flow. This approach has been successful in preserving IIA blood flow in 5 of 7 endograft procedures; in the other 2, IIA occlusion was a predictable event. CONCLUSIONS Direct suturing of an aortoiliac stent-graft to the CIA bifurcation via an extraperitoneal approach is a useful method of maintaining IIA perfusion. However, further study is required to identify patients at high risk of pelvic ischemia who would benefit from such intervention.

Abstract
Women account for approximately 25% of patients with AAAs, but unfortunately, only 8-10% of patients considered candidates for endovascular treatment during prospective trials were women. We reviewed our experience with open surgical and endovascular techniques before and after the FDA approval of the Ancure and AneuRx devices to evaluate our results and the role of endovascular treatment of AAAs in women. From January 1999 to August 2000, 269 patients underwent elective repair of their AAAs at our institution. The 20-month period was divided into the 10 months before and after the FDA approval of the endovascular devices for comparison. In the initial time period, 75 patients (62 men and 13 women) underwent repair with 40% undergoing endovascular repair. In the 10 months after FDA approval, 194 patients (160 men and 34 women) underwent repair with 87% undergoing endovascular treatment. Ninety-two percent (155) of the patients undergoing endovascular repair in this period were treated with the AneuRx device. These 155 patients were divided into two groups based on gender to compare their early treatment results. The FDA approval of endovascular grafts has profoundly affected the treatment of infrarenal AAAs in the United States. Women continue to account for a small, but complex, proportion of patients treated with available endovascular devices and the results in these patients is worse than their male counterparts. Careful patient selection and meticulous operative techniques are needed to reliably treat women with available endovascular devices. Further developments are necessary to improve the current results and increase the proportion of women being safely and effectively treated with endovascular devices.

Abstract
OBJECTIVE The purpose of our study was to determine the value of three-dimensional (3D) rotational angiography in the assessment of patients to be treated with covered stents for peripheral arterial aneurysms. CONCLUSION Our preliminary experience suggests that 3D rotational angiography appears to be a valid tool in the pre- and perprocedural assessment of patients treated endovascularly for arterial aneurysms.

Abstract
PURPOSE The purpose of this study was to determine the long-term functional outcome after unilateral hypogastric artery occlusion during endovascular stent graft repair of aortoiliac aneurysms. METHODS During a 41-month period, 157 consecutive patients underwent elective endovascular stent graft repair of aortoiliac aneurysms with the Medtronic AneuRx device. Postoperative computed tomography scans were compared with preoperative scans to identify new hypogastric artery occlusions. Twenty-three (15%) patients had unilateral hypogastric occlusion, and there were no cases of bilateral occlusions. Telephone interviews about past and current levels of activity and symptoms were conducted, and pertinent medical records were reviewed. All 23 (100%) patients were available for the telephone interview. A disability score (DS) was quantitatively graded on a discrete scale ranging from 0 to 10 corresponding to "virtually bed-bound" to "greater-than-a-mile" exercise tolerance. Worsening or improvement of symptoms was expressed as a difference in DS between two time points (-, worsening/+, improving). RESULTS Among the 23 patients, two groups were identified: 10 patients (43%) had planned and 13 patients (57%) had unplanned or inadvertent occlusions. The patients in the two groups did not differ significantly in the mean age (73.4 vs 73.7 years), sex (male:female, 9:1 vs 10:3), and duration of follow-up (15.6 vs 14.4 months). Nine (39%) of the 23 patients, five patients in the planned and four patients in the unplanned group, reported significant symptoms of hip and buttock claudication ipsilateral to their occluded hypogastric arteries. The mean decrement from baseline of these nine patients in their DS postoperatively was -3.3. The symptoms were universally noted on postoperative day 1. Although most patients improved (89%), one (11%) never got better. Among those whose symptoms improved, the mean time to improvement was 15 weeks, but with a plateau thereafter resulting in a net decrement of DS of -2.3 from baseline. Finally, when questioned whether they would undergo the procedure again, all 23 patients unanimously answered, "Yes." CONCLUSIONS A significant number (39%) of patients who sustain hypogastric artery occlusion after endovascular aneurysm repair have symptoms. Although most patients with symptoms have some improvement, none return to their baseline level of activity. Despite this, all patients in retrospect would again choose endovascular repair over conventional open repair.

Abstract
PURPOSE To identify a complication of endograft deployment in aneurysmal iliac arteries. CASE REPORT A 71-year-old man was referred for endovascular treatment of a 60-mm-diameter right common iliac artery aneurysm; however, deployment of a homemade covered stent (Palmaz-Schatz and polytetrafluoroethylene) induced shortening of the tortuous external iliac artery, causing an "accordion" deformity. The anomaly proved difficult to treat with serial Wallstent deployment, because the convolution tightened and migrated caudally with each stent deployed, threatening outflow. Finally, after 3 Wallstents were implanted, the contour of the external iliac artery was straight, and flow was unimpeded. However, 3 weeks later, the external iliac artery had recoiled to its original redundant appearance, but flow remained satisfactory. The aneurysm remains excluded, with satisfactory distal flow after 24 months. CONCLUSIONS Implanting endografts in redundant, tortuous arterial segments may prove problematic, since induced straightening by the device precipitates kinking in the redundant system. Although treatment may be required in some situations, the vessels may return to a noncompressed state by removing the delivery system and guidewire.

Abstract
OBJECTIVE Precise diameter changes in iliac artery aneurysms (IAAs) after endovascular graft (EVG) repair are yet to be determined. This report describes the midterm size changes in isolated IAAs 13 to 72 months after treatment with an EVG. METHODS From January 1993 to April 1999, 31 patients with 35 true isolated IAAs (32 common iliac and 3 hypogastric) had these lesions treated with EVGs and coil embolization of the hypogastric artery or its branches. The EVG used in this study consisted of a balloon-expandable stent attached to a polytetrafluoroethylene graft. Contrast-enhanced spiral computed tomographic scans were performed at 3- to 6-month intervals to follow the aneurysms for change in diameter and endoleaks. RESULTS Thirty patients had a decrease in the size of their iliac aneurysms with EVG repair. All EVGs remained patent. All patients, except for one, were followed up for 13 to 72 months (mean, 31 months). The pretreatment aneurysm size ranged from 2.5 to 11.0 cm in diameter (mean, 4.6 +/- 1.62 cm). After EVG treatment, the aneurysms ranged from 2.0 to 8.0 cm in diameter (mean, 3.8 +/- 1.36 cm). The change in aneurysm diameter ranged from 0.5 to 3.1 cm (mean, 1.1 +/- 0.62 cm) with an average change of -0.516 +/- 0.01 cm/y for the first year. Five patients died of their intercurrent medical conditions during the follow-up period. One of the patients had a new endoleak and an increase in common iliac aneurysm size 18 months after EVG treatment, despite an early contrast-enhanced computed tomographic scan that showed no endoleak. This patient's aneurysm ruptured, and a standard open surgical repair was successfully performed. Another patient had a decrease in hypogastric aneurysm size after EVG treatment and no radiographic evidence of an endoleak, but eventually the aneurysm ruptured. He was successfully treated with a standard open surgical repair. CONCLUSIONS EVGs can be an effective treatment for isolated IAAs. Properly treated with EVGs, IAAs decrease in size. The enlargement of an IAA, even if no endoleak can be detected, appears to be an ominous sign suggestive of an impending rupture. IAAs that enlarge should be closely evaluated for an endoleak. If an endoleak is detected, it should be eliminated if possible. If an endoleak cannot be found, open surgical repair should be considered.
