Abstract
OBJECTIVES To evaluate the use of novel technology to treat complex aortic aneurysms involving branches that provide critical end-organ blood supply. METHODS A prospective study was conducted in patients with thoracoabdominal, suprarenal, or common iliac aneurysms (TAA, SRA, or CIA) at high risk for open surgical repair. An endovascular graft using the Zenith platform was customized to fit patient anatomy (TAA or SRA) and combined with Jomed balloon-expandable stent-grafts. Prefabricated hypogastric branches were used with a Zenith abdominal aortic aneurysm (AAA) or Fluency self-expanding fenestrated device in conjunction with a self-expanding stent-graft. Analyses were conducted in accordance with the endovascular aneurysm reporting standards document. Follow-up studies occurred at discharge, 1, 6, and 12 months, and included computed tomography and duplex ultrasound scans, and flat plate radiography. RESULTS Fifty patients were treated (9 TAA, 20 SRA, 21 CIA). The mean aneurysm size was 7.6 cm (TAA), 7.2 cm (SRA), and 6.1 cm AAA size associated with a mean CIA size of 3.8 cm. Bilateral CIA aneurysms were present in 86% (18/21) of patients with CIA aneurysms. Perioperative mortality was 2% (1/50) and resulted from a myocardial infarction after a planned conduit and iliac endarterectomy required for device access. Five late deaths occurred (2 TAA, 2 SRA, 1 CIA), three of which (2 TAA, 1 SRA) were aneurysm related. Failure to access internal iliac arteries occurred in three cases, and two late hypogastric branch thromboses occurred. No visceral branches were lost acutely or occluded during follow-up. Sac shrinkage (>5 mm) was noted in 65% of patients at 6 months and in all patients (10/10) by 12 months. There were no ruptures or conversions, but nine patients required secondary interventions. CONCLUSIONS Branch vessel technology has made it technically feasible to preserve critical end-organ perfusion in the setting of CIA, SRA, and TAA aneurysms. The relatively low acute mortality rate and lack of short-term branch vessel loss are encouraging and merit further investigation. These advances have the potential to markedly diminish the complications associated with conventional management of complex aneurysms.

Abstract
PURPOSE To report a technique to maintain flow to an aneurysmal internal iliac artery (IIA) when treating bilateral common iliac artery (CIA) aneurysms with an aortomonoiliac stent-graft and femorofemoral bypass. TECHNIQUE First, an external iliac artery (EIA) to IIA endograft is placed distal to the IIA aneurysm then the contralateral IIA is embolized with coils. An aortomonoiliac stent-graft extending to the contralateral EIA is placed, and the procedure is completed with a femorofemoral bypass. CONCLUSION Endovascular treatment of bilateral CIA aneurysms and combined with a unilateral IIA aneurysm is a technically demanding procedure. An endovascular repair with retrograde (reverse-U stent-graft) hypogastric artery preservation can be considered a first choice until the use of branched iliac stent-grafts becomes more widespread.

Abstract
Multiple aneurysms are clinically common in population aged over sixty and are caused mainly by atherosclerosis. When occurring in young population other etiologies such as trauma, infections, Bechet's disease, Marfan syndrome, neurofibromatosis or inflammatory disease are responsible for the development of arterial aneurysms. A rare case of multiple aneurysms in a 40-year-old man, affecting the infrarenal part of abdominal aorta, both iliac arteries, common femoral arteries, left femoral superficial and popliteal arteries on, both legs, is reported. The underlying pathology was progressive atherosclerosis, favored by familial hyperlipidemia and excessive cigarette smoking.

Abstract
Inflammatory aneurysms represent only 3-10% of all aortoiliac aneurysms and tend to be more common in men. We report a case of a solitary inflammatory aneurysm of the right common iliac artery in a healthy young woman. The patient presented with persistent abdominal and right flank pain. She had no risk factors for vascular disease, except mild hypertension and a strong family history of aneurysm disease. Her work-up demonstrated a 3.0 cm right common iliac artery aneurysm with intramural thrombus, focal calcification, and perianeurysmal inflammation without evidence of systemic atherosclerosis. There was right hydroureteronephrosis secondary to ureteral compression by the inflammatory aneurysm. She underwent open right common iliac artery aneurysmorraphy with polytetrafluoroethylene interposition graft and concomitant ureterolysis without complication. She remains asymptomatic more than 1 year postoperatively with no evidence of additional aneurysm disease, resolution of her hydroureteronephrosis, and normal kidney function. We report a rare case of a solitary inflammatory aneurysm of the right common iliac artery in a healthy young woman, with a review of the current literature on inflammatory aneurysms.

Abstract
PURPOSE The purpose of this report is to evaluate the use of conventional coils and the Amplatzer Vascular Plug, a type of nitinol-based self-expanding device, to occlude the internal iliac artery in patients undergoing aortoiliac or common iliac aneurysm endograft repair, or both. 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
Internal iliac artery aneurysm is a rare cause of lower gastro-intestinal tract (GIT) haemorrhage. A fifty-four year old male patient presented with massive rectal bleeding. Sigmoidoscopy was not conclusive and pelvic angiography revealed an aneurysm from a branch off the main trunk of the anterior division of the right internal iliac artery that was located in juxtaposition to the sigmoid colon. The aneurysm was successfully obliterated by transcatheter arterial embolotherapy with acrylic glue. A high index of suspicion of internal iliac artery aneurysm as a possible cause of lower GIT haemorrhage is of paramount importance. Pelvic angiography is essential for the diagnosis, and embolotherapy with acrylic glue was an effective treatment method in this patient.

Abstract
Isolated aneurysms of the iliac arteries are extremely rare, comprising less than 2% of all aneurysmal disease. These aneurysms are typically seen in older men. Their natural history, although fairly indolent, carries a significant risk of rupture when the aneurysms have attained a large size. Their operative mortality is significantly higher when undertaken as an emergent versus elective procedure, underscoring the importance of early diagnosis and appropriate management. This article reviews the literature with regard to the natural history, diagnostic workup, and treatment of iliac artery aneurysms. For patients undergoing elective repair, preoperative imaging with computed tomography or magnetic resonance is advocated. Repair is recommended for good-risk patients with aneurysms larger than 3.5 cm. A working classification based on aneurysmal anatomy is provided along with an outline of the suggested open and endovascular surgical options. Results of open and endovascular strategies are summarized and follow-up recommendations are proposed.

Abstract
PURPOSE To report endovascular occlusion of an internal iliac artery (IIA) aneurysm with an Amplatz nitinol vascular occlusion plug. CASE REPORT A 71-year-old asymptomatic man who had previously undergone open aortic aneurysm repair presented for annual follow-up. A bifurcated Dacron graft had been inserted 12 years ago from the infrarenal aorta to the left common femoral artery and the right common iliac artery. The left common iliac artery was ligated proximally, and the left external iliac artery (EIA) provided retrograde flow into the IIA. Magnetic resonance imaging (MRI) revealed a 7.4-cm aneurysm of the left IIA. After transfemoral calibrated catheter angiography was performed, the proximal EIA was occluded with an Amplatz nitinol vascular occlusion plug. In addition, microcoils were placed distal to the vascular plug to achieve complete thrombosis of the vessel. One day after treatment, the patient was discharged free of symptoms after MRI had shown complete obliteration of the IIA aneurysm. At 6 months, the patient was free from symptoms, and angiography confirmed exclusion of the IIA aneurysm. CONCLUSIONS This case illustrates the technical feasibility and successful short-term follow-up of a novel embolization approach to IIA aneurysms in patients with an aortofemoral graft.

Abstract
Vascular surgery is evolving, as other specialities, toward minimally invasive techniques. Presently, 3 approaches to aortoiliac disease are suggested as minimally invasive. Besides the endovascular procedures, laparoscopic techniques and minilaparotomy are being advocated. Although for aneurysmal disease, we favor a totally laparoscopic approach, criticisms raised over laparoscopy-assisted techniques by those advocating minilaparotomy led us to investigate the benefits of the latter technique. We first evaluated the procedure in 7 patients with infrarenal abdominal aortic aneurysm (AAA). We found the procedure impossible to perform with an 8- to 10-cm incision in 6 of the 7 patients. This led us to evaluate causes of failure of the technique. It appeared to us that most of our complications were related to inadequate exposure. Fifty consecutive computed tomography scans from patients with AAA of surgical size were then reviewed to evaluate the aneurysm lengths and compare them to the reported lengths of skin incision for minilaparotomy. Results were expressed adding a total of 2 cm for proximal and distal clamping. Only 2% of patients would present with aneurysms suitable for treatment through an 8-cm midline incision and 30% through a 10-cm incision. We then reviewed the literature on minilaparotomy. We believe that minilaparotomy should be reserved for those patients with purely aortic disease and the appropriate body habitus.

Abstract
A patient who was operated for an abdominal aortic aneurysm 7 years earlier presented with recently discovered iliac and renal artery aneurysms. The renal artery had an angulation of 90 , but the aneurysm was successfully excluded using a covered vascular stent graft placed over an extra stiff guidewire. Even in cases of complex anatomy of a renal aneurysm, endovascular treatment should be considered. With development of more flexible and low-profile endoprosthesis with accurate deployment, these have become more usable.

Abstract
To compare the clinical importance of extracolonic findings at intravenous (IV) contrast-enhanced CT colonography versus those at non-enhanced CT colonography. IV contrast medium-enhanced (n=72) and non-enhanced (n=30) multidetector CT colonography was performed in 102 symptomatic patients followed by conventional colonoscopy on the same day. The impact of extracolonic findings on further work up and treatment was assessed by a review of patient records. Extracolonic findings were divided into two groups: either leading to further work up respectively having an impact on therapy or not. A total of 303 extracolonic findings were detected. Of those, 71% (215/303) were found on IV contrast-enhanced CT, and 29% (88/303) were found on non-enhanced CT colonography. The extracolonic findings in 25% (26/102) of all patients led to further work up or had an impact on therapy. Twenty-two of these patients underwent CT colonography with IV contrast enhancement, and four without. The percentage of extracolonic findings leading to further work up or having an impact on therapy was higher for IV contrast-enhanced (31%; 22/72) than for non-enhanced (13%; 4/30) CT scans (P=0.12). IV contrast-enhanced CT colonography produced more extracolonic findings than non-enhanced CT colonography. A substantially greater proportion of findings on IV contrast-enhanced CT colonography led to further work up and treatment than did non-enhanced CT colonography.

Abstract
PURPOSE To describe an endovascular technique that allows stent-graft treatment of aortoiliac aneurysmal disease affecting both common iliac arteries (CIA), with maintenance of pelvic circulation on one side. TECHNIQUE For patients with aortoiliac aneurysms, both common femoral arteries (CFA) were surgically exposed. One internal iliac artery (IIA) was initially embolized with coils. A bifurcated stent-graft main body was deployed with the proximal end just below the renal arteries. On the ipsilateral side, the stent-graft limb was extended 3 cm beyond the orifice of the embolized IIA into the external iliac artery (EIA) using stent-graft limb extenders. On the contralateral side, the stent-graft limb was deployed so that the distal end was 10 to 15 mm proximal to the patent IIA orifice. Via a left brachial artery access, the IIA was catheterized, and stent-grafts were deployed from the distal end of the contralateral AAA stent-graft limb into the IIA. A femorofemoral crossover graft provided circulation to the leg ipsilateral to the IIA stent-graft, and the EIA on the same side was ligated. The technique can also be modified to treat isolated bilateral CIA aneurysms. CONCLUSIONS By extending the distal aspect of the stent-graft into an IIA, bilateral CIA aneurysms can be excluded while preserving pelvic circulation on one side.

Abstract
Popliteal and femoral aneurysms account for about 70% of the incidence of peripheral aneurysms. Only 4% of aneurysms run their course with the clinical evidence of rupture. The ruptured aneurysm is dangerous because of a potential limb loss as well as due to the threat of lethal outcome in patients at a high surgical risk. Presented herein is a successful experience (first in this country) gained with the treatment of a ruptured femoral aneurysm by means of endoprosthetics using a new stent graft with PTFB coating in a patient at a high risk for traditional surgical treatment.

Abstract
Aneurysms of the superior mesenteric artery are one of the most uncommon visceral artery aneurysms. Despite its rarity they course with high risks of rupture and many constitute a permanent threat to patients's life. The authors report the clinical condition of a male patient, with a large aneurysm of the superior mesenteric artery, diagnosed through the image techniques made during the follow-up of a previously operated aorto-iliac and bilateral popliteal aneurysms. Its clinical presentation and the surgical management are subjected to presentation and discussion.

Abstract
The aim of this study was to evaluate the effectiveness of endovascular repair of anastomotic and true aortic and iliac aneurysms occurring after prior polyester graft repair for abdominal aortic aneurysms (AAA) or aortoiliac obstructive disease. Between July 1999 and January 2003, 14 patients underwent endovascular treatment of aortic pseudoaneurysms (n = 6) or iliac aneurysms (2 patients with pseudoaneurysms and 6 patients with true aneurysms) occurring 4 to 18.4 years (mean, 8.8 years) after open aortic surgery. No patient had symptoms or positive parameters for infection of the original polyester graft. Eleven patients, including one patient with both a proximal anastomotic and a true iliac aneurysm, were treated with AneuRx (n = 8), Talent (n = 2), or Quantum LP (n = 1) bifurcated stent grafts. Three patients with an infrarenal anastomotic pseudoaneurysm were treated with a tube stent graft (Talent [n = 2] and AneuRx [n = 1]). Endovascular stent grafts were successfully inserted in all patients. Procedure-related complications or death was not seen. During a median follow-up of 12 months (range, 3-40) all anastomotic and/or true aneurysms treated with bifurcated stent grafts maintained excluded. However, two out of three patients, treated with a tube graft for proximal aneurysm exclusion, were converted. In both patients the tube stent graft did not migrate from the level of the renal arteries but fixation failed between the stent graft and the previous polyester graft, creating endotension in the thrombus of the aneurysm sac. In one of these patients the old anastomotic aneurysm ruptured 16 months after stent graft placement and the patient died 1 day after conversion because of mesenterial ischemia. At 1 year follow-up the second patient was converted successfully after enlargement of his anastomotic aneurysm due to similar disconnection between the stent graft and the polyester graft. From this experience with endovascular stent grafts, we conclude that these can be used successfully to exclude anastomotic or true aneurysms after open aortic surgery. Exclusion of aneurysms at the proximal anastomosis with tube stent grafts is apparently not durable because of the insecure distal fixation in polyester grafts. Endovascular repair with bifurcated stent grafts, however, seems to be effective at midterm follow-up.

Abstract
PURPOSE Virtual stenting (VS) is a new tool in the 3D processing work station of rotational angiography (RA) systems. This tool enables the 3D visualization of a stent or stent-graft in the site of a stenotic, obstructive or aneurysmatic lesion to be treated. We report the preliminary results obtained with this software in the treatment of segmental stenotic, obstructive or aneurysmal lesions of the iliac artery. MATERIALS AND METHODS Seventeen patients under-went rotational angiography and 3D reformations for one or more stenoses (19 cases), obstructive lesions (2 cases) or aneurysms (2 cases) of the common and/or external iliac artery and were treated with stents in 22/23 of cases. In all cases, the VS tool was applied to the stenotic-obstructive lesion on the identified on the 3D angiogram obtained before the stenting procedure. RESULTS The measurements of the stents/stents-grafts (length, proximal and distal diameter) provided by the tool were compared to those of the stent deployed. In 22/23 procedures, the measurements of virtual stenting and those of the deployed stent showed a good level of concordance. The system failed to provide correct measurements in only one long and tortuous iliac aneurysm. CONCLUSIONS The ''virtual stenting'' tool proved to be reliable and fast, and enabled a more objective selection of the stent to be deployed on a stenotic-obstructive lesion in almost all cases. In cases of aneurysms of marked tortuosity, the system tends to suggest an inappropriate stent. The possibility of manually defining the optimal stent path within the aneurysmal sac might be useful.

Abstract
PURPOSE To assess early and intermediate results of endovascular repair of abdominal aortic aneurysms (EVAR), and to compare them with open surgery (OS) in concurrent patients suitable for both types of treatment. METHODS During 3 years, 180 patients with AAA underwent repair. We excluded patients with ruptured aneurysms (33), juxtarenal aneurysms (11), iliac aneurysms (8), with peripheral embolization (2) and those treated with a cryopreserved homograft (2). From the remaining patients (n=124), we selected those suitable for both techniques (n=83), of which 53 were treated by EVAR and 30 by OS. Analysis was performed using Kaplan-Meier curves and Log Rank tests. RESULTS Hospital mortality was not significantly higher in the OS group (6.6% OS vs. 3.7% EVAR), p=0.55. The EVAR group had significantly shorter operative time, length of hospital stay and less blood loss. The median follow up time was 2.18 years for OR and 1.58 years for EVAR. There were no conversions from EVAR to OS and no differences in late survival (p=0.255, Cox regression analysis) with a cumulative survival rate at 3 years of 89% for EVAR and 73% for OS. By 3 years 24% (95% CI, 11-47%) of EVAR patients had presented endoleaks with an endovascular re-intervention rate of 27% (95% CI, 13-50%). One patient in the OS group needed a late open intervention. CONCLUSIONS EVAR compares favourably with OS in terms of reduction of operative time, hospital length of stay and blood loss. This study did not show a difference in early or late mortality. EVAR durability remains the most critical issue to be addressed.
