Multicenter CT Image-Based Anatomic Assessment of Patients with Aortoiliac Aneurysm Undergoing Endovascular Repair with Iliac Branch Devices. Ann Vasc Surg 2024; 108:484-497. [PMID: 39009130 DOI: 10.1016/j.avsg.2024.05.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 04/29/2024] [Accepted: 05/02/2024] [Indexed: 07/17/2024]
Abstract
BACKGROUND The Global Iliac Branch Study (NCT05607277) is an international, multicenter, retrospective cohort study of anatomic predictors of adverse iliac events (AIEs) in aortoiliac aneurysms treated with iliac branch devices (IBDs). METHODS Patients with pre-IBD and post-IBD computed tomography imaging were included. We measured arterial diameters, stenosis, calcification, bifurcation angles, and tortuosity indices using a standardized, validated protocol. A composite of ipsilateral AIE was defined, a priori, as occlusion, type I or III endoleak, device constriction, or clinical event requiring reintervention. Paired t-test compared tortuosity indices and splay angles pretreatment and post-treatment for all IBDs and by device material (stainless steel and nitinol). Two-sample t-test compared anatomical changes from pretreatment to post-treatment by device material. Logistic regression assessed associations between AIE and anatomic measurements. Analysis was performed by IBD. RESULTS We analyzed 297 patients (286 males, 11 females) with 331 IBDs (227 stainless steel, 104 nitinol). Median clinical follow-up was 3.8 years. Iliac anatomy was significantly straightened with all IBD treatment, though stainless steel IBDs had a greater reduction in total iliac artery tortuosity index and aortic splay angle compared to nitinol IBDs (absolute reduction -0.20 [-0.22 to -0.18] vs. -0.09 [-0.12 to -0.06], P < 0.0001 and -19.6° [-22.4° to -16.9°] vs. -11.2° [-15.3° to -7.0°], P = 0.001, respectively). There were 54 AIEs in 44 IBDs in 42 patients (AIE in 13.3% of IBD systems), requiring 35 reinterventions (median time to event 41 days; median time to reintervention 153 days). There were 18 endoleaks, 29 occlusions, and 5 device constrictions. There were no strong associations between anatomic measurements and AIE overall, though internal iliac diameter was inversely associated with AIE in nitinol devices (nAIE, nitinol = 8). CONCLUSIONS Purpose-built IBDs effectively treat aortoiliac disease, including that with tortuous anatomy, with a high patency rate (91.5%) and low reintervention rate (9.1%) at 4 years. Anatomic predictors of AIE are limited.

Abstract
Background Open abdominal aortic aneurysm (AAA) repair can lead to sexual dysfunction (SD) in men. Objectives To determine the prevalence of SD following open AAA repair, explore whether surgical techniques for aortic reconstruction can have a differential impact on the occurrence of SD, and summarize current knowledge in this field. Methods Retrospective review of 100 patients submitted to open AAA repair between 1995 and 2010 in a quaternary center. Sexual dysfunction was assessed according to questions from the modified International Index of Erectile Function (IIEF), considering the condition before surgical repair and 3 months after surgery. The chi-square test, Fisher's exact test, and Student's t test were used for statistical analyses. Results 100 patients were included (mean age = 66.4 years old). Normal sexual activity, no sexual activity, erectile dysfunction, and retrograde ejaculation with preserved erectile function were found in 36%, 21%, 18%, and 24% of patients, respectively. The group of patients with no sexual activity was older (mean age = 72.3 years old vs 64.5 years old, p < 0.001). Erectile dysfunction prevalence was higher in patients submitted to an aorto-bifemoral bypass (p = 0.032). Retrograde ejaculation was more frequent in patients submitted to an aorto-aortic bypass (p = 0.007). Conclusions Sexual function is a frequent condition intimately associated with the aortic reconstruction technique. The literature review found contradictory results regarding whether the endovascular approach is protective compared with open repair, but clearly demonstrated the importance of techniques targeting preservation of the internal iliac artery and the superior hypogastric plexus.

A systematic review and meta-analysis of the clinical effectiveness and safety of unilateral versus bilateral iliac branch devices for aortoiliac and iliac artery aneurysms. J Vasc Surg 2022; 76:1089-1098.e8.

Abstract
OBJECTIVES Iliac branch devices (IBDs) have been utilized in the treatment of aortoiliac and isolated iliac artery aneurysms. The aims of this systematic review and meta-analysis were to investigate the clinical effectiveness and safety of IBDs. METHODS A systematic review of the literature was conducted by identifying studies in the Medline, EMBASE, and Cochrane databases regarding the outcomes of IBDs in aortoiliac or isolated iliac artery aneurysms between May 2006 and December 2020. Individual studies were evaluated for the following major outcomes: technical success, 30-day mortality, primary patency, endoleak, reintervention, and rates of pelvic ischemia. Furthermore, sub-group meta-analyses were performed to compare the pelvic ischemic events in patients with bilateral IBDs, unilateral IBDs and bilateral internal iliac artery (IIA) embolization/coverage. RESULTS 45 studies with a total of 2736 patients undergoing unilateral or bilateral IBDs met inclusion criteria and were included in the analysis. The pooled technical success rate of IBD was 98.0% (CI: 97.3-98.7%). Following IBD treatment, the 30-day mortality rate was 0.4% (CI: 0.07-0.70%); 30-day patency was 98.4% (CI: 97.7-99.0%); buttock claudication developed in 1.84% (CI: 1.26-2.41%); endoleak occurred in 11.9% (CI: 9.2-14.7%) and re-intervention in 7.6% (CI: 5.65-9.58%). Furthermore, in the patients with bilateral iliac artery involvement the pooled estimate rates of buttock claudication were 0.7% in bilateral IBD group, 7.9% in unilateral IBD with contralateral IIA embolization patients and 33.8% in bilateral IIA embolization/coverage patients, which were statistically significant among the three groups. Sexual dysfunction was 5.0% in bilateral IIA occlusion group, which was significantly higher than that in IBD groups. CONCLUSIONS The utilization of IBDs in treatment of aortoiliac or isolated iliac artery aneurysms is associated with high technical success rates as well as low incidences of pelvic ischemia. The risk of postoperative buttock claudication can be further decreased with both IIA preservation if patients are anatomically suitable for bilateral IBDs.

Abstract
Endovascular aneurysm repair (EVAR) is now considered the first choice treatment modality for abdominal aortic aneurysm (AAA) treatment. Advocates for endovascular strategies will try to treat all AAA by EVAR, regardless if the anatomy is conducive for treatment or not. However, the long-term outcomes of EVAR outside the instructions for use (IFU) due to a hostile aneurysmal neck or iliac artery anatomy are known to be poor. The EVAR procedures can be classified according to the technical difficulty, IFU, and need for visceral revascularization: standard, adjunctive, and complex EVAR. The situation required for adjunctive procedures can be classified as the following four steps: a hostile neck (i.e., short or severely angled); large inferior mesenteric or lumbar artery; tough iliac artery anatomy, such as a short common iliac artery and stenotic external iliac artery; and limitations in vascular access. This article will discuss the adjunctive procedures to overcome hostile aneurysm neck and unsuitable iliac artery anatomy.

Abstract
BACKGROUND Aortic anatomy is important in determining the success or failure of endovascular aortic aneurysm repair (EVAR). Endoleak is another issue which should be addressed for a long-term durability of the procedure. Internal iliac artery (IIA) embolization is required to prevent type II endoleak when the iliac landing zone is not sufficient such that the iliac limb should be extended down to the external iliac artery (EIA). Pelvic ischemia is an important complication of IIA embolization, but its incidence and severity is not exactly known. Our experience suggests this to be common but not severe. In this study we reviewed the clinical outcomes of patients who underwent IIA embolization to facilitate EVAR at one of the major tertiary medical centers in South Korea. METHODS We performed a retrospective review of the patients who underwent IIA embolization prior to EVAR between November 2005 and June 2018 at a single tertiary medical center in South Korea. Patients were interviewed via telephone to determine the severity of buttock claudication according to a previously defined pain scale. RESULTS The majority of 139 patients in both the unilateral and bilateral IIA embolization groups experienced no (N.=83, 60.0%) or mild (N.=51, 36.7%) buttock claudication. Only three patients in the unilateral IIA embolization group reported that their symptoms affected daily life, but without need for any measures for pain relief. Symptom duration was longer in the bilateral embolization group (12.6 months) compared to the unilateral group (6.6 months) without statistical significance (P=0.559). There were no critical complications such as buttock necrosis, spinal cord ischemia, or ischemic colitis. CONCLUSIONS Based on our experience, IIA embolization does cause buttock claudication of a certain degree. However, the most of them experienced mild discomfort rather than such symptoms severely affect their quality of life. Considering the risks of general anesthesia and complications of surgical procedures, IIA reconstruction along with EVAR may not be necessary.

Abstract
While surgical treatment for abdominal aortic aneurysm (AAA) is a standard operation, prevention of complication is important. Intestinal ischemia of the sigmoid colon and/or rectum after AAA surgery is severe and has a high mortality rate although occurrence frequency is low. The most important thing to prevent is the preoperative and intraoperative evaluation of the left hemicolon and rectal circulation. Measurement of inferior mesenteric artery stump pressure is also useful. From the viewpoint of prevention of buttock claudication, it is desirable that internal iliac artery (IIA) blood flow is preserved, but aggressive IIA reconstruction adaptation is considered to be low. For erectile function, it is important that the antegrade blood flow from the IIA to the internal pudendal artery on at least one side is preserved or reconstructed. To prevent retrograde ejaculation, it is important to preserve the superior hypogastric plexus and one side of the lumbar splanchnic nerve, and the hypogastric nerve. Understanding and mastering local anatomy and pathophysiology is important in preventing complications, and we must also remember that we always keep watchful surgical operations in mind in order to prevent tissue damage.

Abstract
AIM To report our experience about hypogastric artery coverage during endovascular aneurysm repair (EVAR) for aortoiliac aneurysms in patients younger than 80 years (group A) compared with octogenarian patients (group B). METHODS Data of consecutive EVAR with hypogastric artery coverage from 01/1998 to 12/2016 were retrospectively analyzed. Primary outcomes were the occurrence of ischemic colitis, type II endoleak and buttock claudication both at 30 days and in the long term. P values less than 0.05 were considered statistically significant. RESULTS The hypogastric artery was covered in 107 patients. Twenty-three (21.5%) were octogenarian (group B). At 30 days, one type II endoleak occurred in group B, whereas 16 patients of group A experienced buttock claudication. There were no cases of ischemic colitis. During follow-up (median 63.5 months), no cases of ischemic colitis occurred. Six new type II endoleaks were recorded (five in group B and one in group A, P = 0.0001). Buttock claudication persisted in four patients of group A. No new cases of buttock claudication were observed. CONCLUSION Unilateral hypogastric artery coverage during EVAR for aortoiliac aneurysms can be performed with an acceptable rate of postoperative complication. Postoperative buttock claudication was more frequent in younger patients, whereas a type II endoleak occurred mostly in octogenarian patients during follow-up.

Abstract
Purpose: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) involving the common iliac artery requires extension of the stent-graft limb into the external iliac artery. For this procedure, internal iliac artery (IIA) embolization is performed to prevent type II endoleak. In this study, we investigated the frequency and risk factor of buttock claudication (BC) in patients having interventional embolization of the IIA. Materials and Methods: From January 2010 to December 2013, a total of 110 patients with AAA were treated with EVAR in our institution. This study included 27 patients (24.5%) who had undergone unilateral IIA coil embolization with EVAR. We examined hospital charts retrospectively and interviewed by telephone for the occurrence of BC. Results: Mean age of total patients was 71.9±7.0 years and 88.9% were males. During a mean follow-up of 8.65±9.04 months, the incidence of BC was 40.7% (11 of 27 patients). In 8 patients with claudication, the symptoms had resolved within 1 month of IIA embolization, but the symptoms persisted for more than 6 months in the remaining 3 patients. In univariate and multivariate analysis, risk factors such as age, sex, comorbidity, patency of collateral arteries, and anatomical characteristics of AAA were not significantly related with BC. Conclusion: In this study, BC was a frequent complication of IIA embolization during EVAR and there was no associated risk factor. Certain principles such as checking preoperative angiogram, proximal and unilateral IIA embolization may have contributed to reducing the incidence of BC.

Abstract
Objective The purpose of this study was to evaluate the effectiveness of detachable interlock microcoils for an embolization of the internal iliac artery during an endovascular aneurysm repair (EVAR). Materials and Methods A retrospective review was conducted on 40 patients with aortic aneurysms, who had undergone an EVAR between January 2010 and March 2012. Among them, 16 patients were referred for embolization of the internal iliac artery for the prevention of type II endoleaks. Among 16 patients, 13 patients underwent embolization using detachable interlock microcoils during an EVAR. Computed tomographic angiographies and clinical examinations were performed during the follow-up period. Technical success, clinical outcome, and complications were reviewed. Results Internal iliac artery embolizations using detachable interlock microcoils were technically successful in all 13 patients, with no occurrence of procedure-related complications. Follow-up imaging was accomplished in the 13 cases. In all cases, type II endoleak was not observed with computed tomographic angiography during the median follow-up of 3 months (range, 1-27 months) and the median clinical follow-up of 12 months (range, 1-27 months). Two of 13 (15%) patients had symptoms of buttock pain, and one patient died due to underlying stomach cancer. No significant clinical symptoms such as bowel ischemia were observed. Conclusion Internal iliac artery embolization during an EVAR using detachable interlock microcoils to prevent type II endoleaks appears safe and effective, although this should be further proven in a larger population.
