Abstract
Isolated external iliac artery aneurysms are a very rare occurrence. We present the case of a patient with a very large symptomatic isolated external iliac artery aneurysm found incidentally on imaging for other reasons. Due to his compressive symptoms, he underwent uncomplicated open repair of his aneurysm. We also discuss the etiology and management options for this rare entity.

Ann Vasc Surg 2019; 58:108-114. [PMID: 30731228 DOI: 10.1016/j.avsg.2018.10.039] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2017] [Revised: 02/08/2018] [Accepted: 10/16/2018] [Indexed: 11/19/2022]
Abstract
BACKGROUND We prospectively evaluated the modified sandwich technique for treatment of complex aortoiliac arterial lesions using commercial stent grafts selected according to the arterial cross-sectional area. The primary outcomes were technical feasibility and mid-term follow-up results. METHODS We prospectively enrolled 13 patients (mean age 63.85 ± 6.12 years) with aortoiliac arterial lesions (5 infrarenal abdominal aortic dissections, 1 lower abdominal aortic occlusion, 5 iliac artery aneurysms, 1 external iliac arterial pseudoaneurysm, and 1 type IB endoleak following endovascular aneurysm repair) for endovascular repair with the modified sandwich technique. All lesions were complex and unsuitable for routine endovascular treatment. The bifurcated stent-graft diameters were determined by calculating the arterial cross-sectional area. Success and complication rates were recorded. Patients were followed for 20.69 ± 6.51 (range 6-31) months and stent patency determined by contrast-enhanced ultrasound and computed tomography 1, 3, and 6 months post-operatively and every 12 months thereafter. RESULTS The initial technical success rate was 100%, and no surgical complications occurred. The primary patency of the stent grafts was 100% during follow-up. Post-procedural type I "gutter" endoleaks occurred in 4 patients (30.8%) after 1 month. At 3 months, the endoleaks in 3 of the 4 patients had disappeared without treatment, and the remaining endoleak resolved after coil embolization. CONCLUSIONS The sandwich technique is a safe and effective therapy for complex aortoiliac arterial lesions. Stent-graft sizes based on the arterial cross-sectional area can ensure technical success and reduce the rate of "gutter" endoleaks.

Abstract
BACKGROUND Iatrogenic vascular injuries, due to the particular nature of such pathology, are associated with high morbidity and mortality in the postoperative period. OBJECTIVES The objective of this study was to present a case of non-classic approach to the therapy of iatrogenic arteriovenous fistula. MATERIAL AND METHODS We present a case of a 17-year old female patient admitted to the Department of Vascular, General and Oncologic Surgery (Copernicus Memorial Hospital, Łódź, Poland) due to an iatrogenic injury to the common iliac vein and artery, following neurosurgical intervention on the spine. Two weeks prior to admission, the patient underwent surgery in the Neurosurgery Clinic for herniated nucleus pulposus and lumbar spine scoliosis. The imaging diagnostic revealed the presence of a pseudoaneurysm of the right common iliac artery and arteriovenous fistula between the right common iliac vessels. The patient was qualified for endovascular treatment. Two self-expanding covered stents were successfully deployed. The clinical and radiological outcome of the procedure was good. The postoperative period was uneventful. The patient was discharged home on the 3rd postoperative day. RESULTS The control examinations (directly after the procedure and 6, 12, 24 and 32 months thereafter) revealed full patency of the iliac vessels, as well as no recurrence of arteriovenous fistula, nor a pseudoaneurysm of the right common iliac artery. No symptoms of either chronic limb ischaemia or venous insufficiency were observed. CONCLUSIONS Iatrogenic vessel injury, being a complication of neurosurgical and orthopedic surgeries, may be overlooked and remain undetected both in intraand postoperative period. Modern imaging techniques allow for an adequate diagnosis of the injury and planning the treatment of arteriovenous fistula. The endovascular procedures are the method of choice in patients with arteriovenous fistulas of iliac vessels, alternative to open surgery.

Abstract
Objective This study was performed to assess the efficacy and outcome of endovascular aneurysm repair (EVAR) for treatment of primary mycotic aortic aneurysms (PMAAs). Methods Fourteen consecutive patients who presented with PMAA from April 2010 to July 2017 were retrospectively reviewed. Preoperative, intraoperative, and postoperative clinical data were recorded, and late infection-related complications and long-term survival were assessed. Results The aneurysms were located in the abdominal aorta in 10 patients and in the left common iliac artery in 4 patients. Positive microbial cultures were found in 12 patients, including Salmonella species in 11 and Streptococcus in 1. The remaining two patients had negative culture results. Ten patients received preoperative antibiotics before elective EVAR for 7 ± 9 days after admission. Four patients who underwent emergent EVAR due to ruptured aneurysms were given their first dose of antibiotics before EVAR. Three patients underwent surgical drainage, and six underwent percutaneous drainage within 30 days after EVAR. No death occurred within 30 days of the initial procedure. The mean follow-up was 34.8 (range, 3-84 months). One patient underwent re-intervention to resolve obstruction of the iliac/femoral artery 5 months postoperatively. Relapse of infection occurred in six patients (42.8%) during follow-up; infection-related death occurred in three of these patients. The other patients recovered with either conversion to open radical surgery or medical therapy. The actuarial 7-year survival after EVAR was 75.7%. Conclusions EVAR and aggressive antibiotic therapy might be suitable for PMAAs. Favorable results may be typical for infection caused by Salmonella.

Abstract
BACKGROUND The aim of this study is to describe our institutional experience using iliac branch grafts (IBGs) in aortoiliac aneurysm repair. METHODS From October 2009 to April 2016, 41 consecutive patients (all men), mean age 71.7 years (range 55-87), underwent IBG implantation. Abdominal aortic aneurysm with common iliac artery involvement (n = 21) or bilateral common iliac artery aneurysms (n = 20) were indications. Computed tomography was used to evaluate patency and postoperative endoleaks within 1 month of implantation and after 1 year. RESULTS A total of 42 IBGs were deployed in 41 patients successfully. One hundred percent of grafts implanted were patent at 1 month and at annual follow-up. There was 1 mortality at 30 days, due to acute renal failure. Sixteen type II and 1 type Ib endoleaks were found, for which 3 reinterventions were performed and the remainder treated conservatively. Five patients had complications which required reintervention. CONCLUSIONS IBG placement has excellent short-term outcomes and potential to limit buttock claudication in the treatment of abdominal aortic aneurysms involving the iliac arteries.

Abstract
A total of 576 patients underwent endovascular aneurysm repair using main body devices for treatment of abdominal aortic aneurysms or iliac artery aneurysms. During follow-up, type IIIb endoleaks caused by fabric tear occurred in six patients (1.0% [6/576]). The device used was Zenith (Cook Medical, Bloomington, Ind) in five cases and Talent (Medtronic, Santa Rosa, Calif) in one case. All endoleaks were close to the flow divider of the main body devices. The distance between the lower renal artery and the top end of the contralateral leg was 53 ± 14 mm. Bell-bottom-shaped Excluder (W. L. Gore & Associates, Flagstaff, Ariz) legs were placed parallel from the top of the main body device through both legs to treat these endoleaks. In two patients, coil embolization was required to treat gutter endoleaks. Postoperative computed tomography showed the obliteration of type IIIb endoleaks in all patients. Our technique may be an acceptable method for treatment of type IIIb endoleaks, especially when they occur near the flow divider.

Abstract
OBJECTIVE This study evaluated and compared the long-term clinical outcomes of endovascular repair of infrarenal aortoiliac aneurysms (EVAR) vs EVAR with preservation of antegrade internal iliac artery (IIA) perfusion using iliac branched devices (EVAR-IBDs). METHODS From October 1998 to August 2015, patients with infrarenal aortoiliac aneurysmal (AIA) disease at high risk for conventional open surgery were enrolled in a prospective physician-sponsored investigational device exemption trial. Clinical data of 75 patients treated with EVAR-IBD and 255 with standard EVAR were analyzed. Technical success, perioperative outcomes, mortality, device patency, endoleak rates, and reinterventions during a follow-up of 10 years were analyzed. RESULTS There were 87 IBDs deployed in 75 patients. Technical success rate was 97%. Mortality at 30 days was 1.3%. Freedom from aneurysm-related mortality at 3, 5, and 10 years was 99%. Freedom from a type I or III endoleak at 3, 5, and 10 years was 99%. Freedom from secondary reinterventions at 3, 5, and 10 years was 86%, 81%, and 81%, respectively. Primary patency of the IBDs at 3, 5, and 10 years was 94%, 94%, and 77%, respectively. Twenty-four percent of patients underwent EVAR for concomitant AIA disease (EVAR-AIA), and 78% were managed by staged IIA embolization before EVAR. No statistically significant difference in freedom from aneurysm-related mortality, limb occlusions, or endoleak rates was identified in patients with EVAR-AIA vs EVAR-IBD (P > .05). There were significantly more secondary reinterventions in the EVAR-AIA group compared with the EVAR-IBD group (hazard ratio, 0.476, 95% confidence interval, 0.226-1.001; P = .045). CONCLUSIONS EVAR of infrarenal AIAs with preservation of antegrade flow to the IIA using IBDs is feasible with long-term sustained durability. Serious considerations should be given to the use of IBDs in patients with infrarenal AIAs meeting appropriate anatomic criteria.

Abstract
BACKGROUND Spontaneous dissection of iliac arteries, without involvement of the aorta, is rare. Only few cases of endovascular treatment of this condition are reported in the current literature. METHODS We report false lumen embolization strategy as an adjunct to stent grafting of the true lumen. RESULTS A 68-year-old male patient was admitted to our institution with the incidental finding of an isolated iliac dissection with a false lumen aneurysm. He was electively treated with successful segmental iliac stent grafting to cover the primary entry tear in the common iliac artery. Coil embolization of the false lumen was chosen to provide distal seal of the false lumen aneurysm. CONCLUSIONS As in the treatment of aortic dissections, also in the iliac arteries, false lumen thrombosis should be targeted. To our knowledge, this is the first case of false lumen embolization of an isolated iliac dissection reported in literature. The technique we report was effective and could be easily reproduced.

Abstract
BACKGROUND The aim of this study is to evaluate the short- and mid-term results of the Zenith bifurcated iliac side branch device (ZBIS) in the treatment of common iliac artery (CIA) aneurysms, and to assess risk factors for intraoperative internal iliac artery (IIA) thrombosis. METHODS All patients who underwent endovascular treatment of either an isolated CIA aneurysm or an aortoiliac aneurysm using the ZBIS device in the departments of vascular surgery of Strasbourg (France) and Lausanne (Switzerland) between January 2010 and December 2014 were retrospectively collected. RESULTS Thirty-one implantations were performed: 30 patients underwent 31 endovascular CIA aneurysm treatments with the ZBIS device. Mean operative time was 188 min. Technical success was obtained in 26 implantations (84%). In 5 implantations (16%), the final angiogram revealed an IIA thrombosis. Thirty-day mortality was 3.2%. Thirty-day morbidity was 13.3%. Mean follow-up was 15 months. Overall survival was 96% at 1 year and 89% at 2 years. In intention-to-treat analysis, primary patency of the internal iliac side branch was 84% at 1 year and 76% at 2 years (5 peroperative IIA occlusions and 1 late occlusion). Freedom from reintervention was 89% at 1 and 2 years. One case of type III endoleak and 2 cases of type II endoleaks were identified. Only type III endoleak required an additional intervention with a covered stent. Aneurysm diameter decreased in 15 implantations (48%) and remained stable in 16 implantations (52%). Clinical, radiological, and peroperative parameters were analyzed to identify risk factor for intraoperative thrombosis of the internal iliac side branch. Notion of intraoperative difficulties (any additional procedure that was not initially planned and increasing the operating time) appeared as a risk factor in multivariate analysis (P < 0.01, standard deviation 1.27, odds ratio 30.6). CONCLUSIONS The main findings of our study is that the procedure can be difficult to perform in particular conditions and can lead to peroperative failure in these cases, highlighting the need for adequate patients screening. When technical success is obtained, outcomes can be considered as satisfactory.

Abstract
Use of endovascular means is gaining ever greater acceptance in the treatment of aorto-iliac aneurysms. Especially, the treatment of patients with common iliac aneurysms (CIAs) may be very challenging due to the complexity of the underlying disease with often involvement of the hypogastric artery. Additionally, the variety of endovascular therapeutic options such as the use of iliac branch devices, parallel grafts, the bell-bottom technique or coil embolization of the hypogastric artery and overstenting of the origin represents significant limitation regarding the presentation of a clear and robust endovascular therapeutic algorithm. Aim of the present article was the demonstration of the institutional experience with the endovascular management of CIAs in order to provide a clinical recommendation and algorithm.

Abstract
Spontaneous dissection of the iliac artery is very rare but known as a complication of highenergy traumatic injuries and has been reported in connection with pregnancy, collagen diseases, and alpha-1-antitrypsin deficiency. The authors report a 42-year-old man with an acute dissection of the common iliac artery during exercise. Groin pain and claudication were the early symptoms. Computerized angiotomography was diagnostic. Operative iliac artery reconstruction was performed. A prerelease control computed tomography examination showed a dissection of the distal aorta and left iliac artery. To their knowledge, the combination of the 2 dissections has not been previously published.

Abstract
Repair of isolated iliac aneurysm with stent-graft implantation and internal iliac coverage may induce significant type II endoleak from patent internal iliac refilling leading to ongoing aneurysm growth. Subsequent treatment of such complication can be challenging especially in case of bilateral iliac involvement. Open repair is technically demanding and often a high risk procedure, while embolization via transfemoral approach is unviable due to the stent-graft coverage precluding direct antegrade access between the common and the internal iliac lumen. Percutaneous retrograde embolization from superior gluteal artery is a feasible technique in case of impossible access through the origin of internal iliac artery.

Abstract
Purpose: To report a percutaneous technique for endovascular repair of iliac artery aneurysms using commercially available materials. Methods: Ten patients (9 males; mean age 65 ± 11 years) presented with 11 isolated iliac artery aneurysms; 3 patients were asymptomatic. Stent-grafts were customized for each patient from polytetrafluoroethylene grafts with Palmaz stents sutured at either end of the tube. The devices were delivered percutaneously through standard 14F sheaths and deployed by balloon dilation. Results: All iliac aneurysms were excluded without procedural incident. One patient with chronic renal insufficiency (baseline serum creatinine 1.9 mg/dL) experienced transient contrast-induced renal failure inhospital. The average hospital stay was 2.5 days (range 1 to 7). One vessel thrombosed 2 weeks following the procedure; the culprit stenosis at the site of arterial cannulation was dilated. One patient died of myocardial infarction at 6 weeks. The remaining eight grafts are patent and free of endoleak at a mean 14-month follow-up. Conclusions: This percutaneous technique appears to be an acceptable alternative to open surgical repair.

Abstract
Purpose: To test whether conventional computed tomography scanning (CT) and contrast aortography (CA) provide adequate data for planning endovascular aortic grafting by measuring 33 parameters in patients having both imaging examinations for evaluation of abdominal aortic aneurysms (AAA). Methods: Fifty consecutive patients with AAA (41 men, 9 women; average age 65 years) had CT and CA (mean 26 days between exams). The data collected and analyzed included: 8 sites of diameter, 4 lengths, 6 angles, and 15 other dimensional measurements. Results: Conflicts between CA and CT data were common. Eighteen patients appeared to have a distal cuff by CA but not by CT. Proximal neck length could not be assessed by CT in 5 and had a difference between CA and CT > 1 cm in 25 patients. CA overestimated neck length in 11 patients. Common iliac artery angulation > 60° occurred unilaterally in 27 patients and bilaterally in 5. Seven patients had both iliac aneurysm and > 60° iliac angulation. Thirteen patients had one or more iliac aneurysms (> 2 cm) shown by CT but not by CA. Conclusions: For endovascular graft planning: (1) more detailed measurement is required than for traditional surgery; and (2) conventional CT and CA are complementary imaging studies, but each has important limitations.

Abstract
Purpose: To test an endovascular aneurysm exclusion system in the presence of a wide range of challenging anatomic features. Methods: Bifurcated endovascular stent-grafts were inserted in 52 patients and followed with serial computed tomography for up to 3 years. The device underwent several modifications during this time, the most significant of which represent the difference between the homemade (n = 42) and industry-made (n = 10) versions. Results: The initial procedural success rate was 92% in the homemade group and 100% in the industry-made group. In the 3 years of follow-up, the long-term success rate was 64% in the homemade group and 90% in the industry-made group. The primary reasons for failure in the homemade group were graft thrombosis due to kinking early in the series and proximal stent migration later in our experience. All cases of migration occurred when the neck was < 15 mm in length, the neck was lined with thrombus, or the stent was implanted > 15 mm from the renal arteries. Kinking was subsequently overcome by implanting Wallstents throughout the graft limbs. The sole failure in the industry-made group was a case in which collateral perfusion reached the aneurysm through patent lumbar arteries. Conclusions: The fruits of this experience are a better technique, a better device, and, most importantly, a better understanding of the system's limits, as reflected in the current selection criteria.

Abstract
Purpose: To report an unusual case of endovascular abdominal aortic aneurysm (AAA) exclusion in which a fenestrated stent-graft was used to seal a proximal Type I endoleak. Methods and Results: An 84-year-old man with a 6.0-cm AAA underwent an aortomonoiliac aneurysm exclusion procedure that was complicated by a proximal endoleak. Because the patient had no right kidney, an additional stent-graft was designed to cover the right renal artery stump while preserving left renal perfusion through a fenestration in the graft material. This approach was successful in obliterating the endoleak around the proximal attachment site, but flow through the lumbar arteries remained. Conclusions: The use of a fenestrated stent-graft is feasible, but the type of fenestration in this case has limited applicability owing to the rarity of patients with suitable anatomy.

Abstract
UNLABELLED Abdominal aortic aneurysm (AAA) is related with higher age and poses a serious threat to the patient´s life. Aneurysms larger than 5.5 cm in diameter are indicated for open or endovascular repair. Giant aneurysms are rarely encountered due to a high risk of rupture. We present a case report of such a giang aneurysm and its open repair. KEY WORDS abnominal aortic aneurysm - iliac artery aneurysm - open repair - complications.

Abstract
Transcatheter embolization has evolved from the use of autologous clot as the embolic agent, to stainless-steel coils, to braided-nitinol vascular plugs. However, there are disadvantages to platinum and metal coils, including procedural time, radiation exposure, mass effect, risk of distal embolization, recanalization, imaging artifacts, and cost. Therefore, a large vessel-occluding device is needed to mitigate these current disadvantages. The Medusa Multi-Coil (MMC; EndoShape, Inc) is a Food and Drug Administration (FDA)-approved embolization device constructed primarily of radioopaque coils with synthetic fibers to promote thrombogenicity, and a unique delivery platform with both proximal and distal attachment to assist with precise placement. We report our experience with the endovascular treatment of internal iliac artery aneurysms using platinum coils vs MMCs.

Abstract
External iliac artery (EIA) pseudoaneurysms are a well-known complication after arterial catheterization procedures. Most develop as a result of high femoral puncture. Small asymptomatic pseudoaneurysms are usually of no consequence but large symptomatic pseudoaneurysm carries a significant risk of rupture with serious life-threatening consequences and needs to be treated. We report here a case of EIA pseudoaneurysm in a 60 year old male patient after a cardiac catheterization procedure. CT angiography demonstrated a large pseudoaneurysm arising from the EIA and compressing the urinary bladder. Patient complained of abdominal pain and felt dizzy and required transfusions due to rapidly developing anaemia secondary to blood loss. Conventional angiography revealed free extravasation of contrast from the EIA. Percutaneous intervention through femoral access was performed by deploying a covered stent which effectively sealed off the perforation site with no evidence of contrast extravasation.

Abstract
Endovascular aneurysm repair requires a suitable anatomy for placement of covered stent grafts, which includes a non-aneurysmal distal landing zone within the common iliac arteries. Patients with iliac artery aneurysms, thus, are often not candidates for this minimally invasive repair, as extension of the graft to an appropriate site would cover the internal iliac artery and result in significant symptoms related to poor pelvic perfusion. We present two cases of common iliac artery aneurysms treated by modified endovascular techniques with good results. Select patients with iliac artery aneurysms may be candidates for endovascular repair. These patients should be referred to centers familiar with these techniques.
