Abstract
Successful endovascular aneurysm repair can be achieved with favorable aortic and iliac arterial anatomies. However, patients with challenging iliac anatomy, such as stenotic, calcified, tortuous arteries, or concomitant iliac artery aneurysms, are commonly encountered. Such a hostile iliac anatomy increases the risk of intraprocedural complications and worsens long-term outcomes. This review addresses various technical options for treating patients with a hostile iliac anatomy, including innovative endovascular solutions, physician-modified endografts, and hybrid procedures. These considerations demonstrate the wide scope of therapies that may be offered to patients with an unfavorable iliac anatomy.

Saldana-Ruiz N, Tachida A, Mossman A, Cure R, Larimore A, Dansey K, Starnes BW, Zettervall SL. Iliac tortuosity increases reinterventions but not adverse outcomes following repair of juxtarenal aneurysms using physician-modified endografts. J Vasc Surg 2024; 79:497-505. [PMID: 37923024 DOI: 10.1016/j.jvs.2023.10.053] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 10/17/2023] [Accepted: 10/24/2023] [Indexed: 11/07/2023]
Abstract
OBJECTIVE Increased angulation of the proximal aortic neck has been associated with complications following endovascular repair of infrarenal aortic aneurysms, including increased incidence of endoleaks, stent migration, secondary interventions, and conversions. However, knowledge on the impact of aortoiliac tortuosity on outcomes following fenestrated repair remains limited. This study aims to quantify the effect of aortoiliac tortuosity on outcomes following fenestrated repair. METHODS A single-center, retrospective review of all patients who underwent a physician-modified endovascular repair for the treatment of juxtarenal aortic aneurysms under a single physician-sponsored investigation device exemption study from 2011 to 2021 was performed. Center luminal lines and geometric distances were obtained using TeraRecon software (San Mateo, CA). A tortuosity index was calculated (tortuosity index = centerline distance/geometric line distance) for each iliac vessel as well as for the infrarenal aorta according to Society for Vascular Surgery reporting standards. Aortic and iliac tortuosity were assessed independently and stratified as low and high. Demographics, comorbidities, anatomic and operative details, and outcomes were compared using univariable and multivariable analysis. RESULTS A total of 135 patients were identified. Thirty-eight patients (28%) had high aortic tortuosity, and 55 patients (42%) had high iliac tortuosity. Patients with high tortuosity were older (aortic: 78 vs 76 years; P = .04; iliac: 78 vs 75 years; P = .01) and differed by sex. Twenty-two percent of men and 50% of women had high aortic tortuosity (P = .01). Forty-seven percent of men and 20% of women had high iliac tortuosity (P = .01). There were no differences in comorbidities based on aortic tortuosity, but coronary artery disease (high: 58% vs low: 36%; P = .01) and hypertension (high: 69% vs low: 86%; P = .02) differed based on iliac tortuosity. Aneurysm diameter was larger for patients with high iliac tortuosity (72 mm vs 64 mm; P < .01), and fluoroscopy time was longer for patients with high aortic tortuosity (41 vs 31 minutes; P = .02). When outcomes were assessed, high iliac tortuosity was associated with increased rate of reinterventions (hazard ratio, 2.6; 95% confidence interval, 1.2-6.0) and type 1 or 3 endoleak (hazard ratio, 5.2; 95% confidence interval, 1.7-16); however, all other outcomes were similar. CONCLUSIONS Among patients treated with physician-modified endovascular repair for juxtarenal aneurysms, iliac tortuosity but not aortic tortuosity, is associated with increased reinterventions and type 1 or type 3 endoleaks. Long-term follow-up is critical for patients with high iliac tortuosity to ensure that high-risk endoleaks are identified and treated early to avoid the risk of rupture.

Preliminary outcomes of the LifeStream balloon-expandable stentgraft in Zenith Iliac branch device to preserve pelvic circulation: A Korean multicenter study. Asian J Surg 2023; 46:94-98. [PMID: 35123861 DOI: 10.1016/j.asjsur.2022.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 01/01/2022] [Accepted: 01/15/2022] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND To evaluate early outcomes of aortoiliac or isolated iliac artery aneurysm repair using the Zenith® Bifurcated Iliac Side (ZBIS) stent graft combined with the LifeStream™ Balloon Expandable Vascular Covered Stent as a bridging stentgraft. METHODS Between August 2018 and February 2020, 38 patients (37 male, mean age 72.7 years) received 46 LifeStream stents in conjunction with 38 ZBIS stent grafts to bridge hypogastric arteries for aneurysm repair in six university hospitals in Korea. The primary outcomes were technical success rate and procedure-related complications. Secondary outcomes were bridging stent graft patency and re-intervention. RESULTS All procedures were performed as elective standard endovascular aortic aneurysm repair (EVAR) and unilateral iliac branch device (IBD). Mean follow-up was 13.1 months, and patient overall survival rate was 96.7%. Technical success rate was 76.3% (n = 29). Causes of failure included seven total endoleaks; six type Ic and one type IIIc from the IBD junction, one unintentional IIA coverage, and one failure to deploy the IIA stent graft. Procedure-related complications occurred in two patients: one LifeStream migration and one ZBIS stent graft migration. Overall patency rates for the LifeStream and ZBIS stents were 97.4% and 97.2%, respectively. CONCLUSION This multicenter preliminary experience with the LifeStream™ Balloon Expandable Vascular Covered Stent in IBD demonstrated good patency; however, an unexpectedly high rate of type Ic endoleaks was observed. Combined use of the LifeStream stent with the ZBIS stent graft is safe and feasible to preserve pelvic circulation with good patency and a low rate of device-related reintervention.

Abstract
Despite declining incidence and mortality rates in many countries, the abdominal aortic aneurysm (AAA) continues to represent a life-threatening cardiovascular condition with an overall prevalence of about 2-3% in the industrialized world. While the risk of AAA development is considerably higher for men of advanced age with a history of smoking, screening programs serve to detect the often asymptomatic condition and prevent aortic rupture with an associated death rate of up to 80%. This review summarizes the current knowledge on identified risk factors, the multifactorial process of pathogenesis, as well as the latest advances in medical treatment and surgical repair to provide a perspective for AAA management.

Abstract
BACKGROUND To report a novel staged hybrid technique to treat complex juxtarenal abdominal aortic aneurysm (JAAA) associated with at least one iliac artery aneurysm (IA) with no adequate distal fixation zone. METHODS The novel technique herein described has two main "staged" steps. The first step consists in creating an adequate distal fixation zone by endovascular means; after hypogastric embolization an iliac stent-graft has placed from 5 mm above the aortic bifurcation to the external iliac artery. The second step is the surgical resection of the JAAA and graft placement sutured distally to the stent-graft which was always performed the day after. RESULTS The five cases included (mean age 74 years), were rejected for fenestrated or branched endovascular aortic repair or iliac branch devices. Four tube grafts and one aorto-bi-iliac graft were sutured to one stent-graft (N.=3), two stent-grafts in iliac kissing configuration (N.=1) and to a main body of a bifurcated stent-graft (N.=1). Mean follow-up duration was 14 (4-27) months with no mortality. Technical success was obtained in all cases (2 suprarenal clamping). Postoperative complications included two pleural effusions, two transient gluteal intermittent claudications, and one renal failure. CONCLUSIONS The technique herein described seems to be a feasible and cost-effective alternative treatment for selected concomitant complex JAAAs and IAs unsuitable for totally endovascular treatment.

Abstract
OBJECTIVE The bell-bottom technique is a widely used technique to treat aortoiliac aneurysms with preservation of the hypogastric arteries. The published data are scarce with conflicting results regarding the evolution. The aim of this study was to compare the outcomes of patients submitted to endovascular abdominal aortic aneurysm repair with standard technique (S-EVAR) versus bell-bottom technique. METHODS This retrospective cohort study compared the outcomes of standard endovascular aneurysm repair (<16 mm iliac limbs) and bell-bottom technique (≥16 mm iliac limbs) in a tertiary vascular center between 2010 and 2015. The end points of this study were type IB endoleak, reintervention and 30-day mortality. The follow-up protocol included CT scans within 30 days of implantation and 12 months. Duplex ultrasound was performed yearly thereafter. RESULTS Two hundred and three patients were treated with bell-bottom technique (n = 84, mean age 72.2 ± 8.9) and S-EVAR (n = 119, mean age 72.7 ± 8.4). The overall 30-day mortality was 1.9%, with no significant difference between groups. There was higher prevalence of coronary heart disease in the bell-bottom technique group compared to the S-EVAR group (41.6% vs. 18.4%, p < 0.01). One patient in the S-EVAR group (0.85%) and four patients in the bell-bottom technique (4.6%) developed type IB endoleak. The mean follow-up period was 35.2 ± 30.4 months. By Kaplan-Meier analysis, freedom from type IB endoleak in 80 months was 85.2% in the bell-bottom technique group and 98.7% in the S-EVAR group (p = 0.05). The freedom from reintervention in 80 months was 74.0% in the bell-bottom technique group and 94.1% in the S-EVAR group (p = 0.6). CONCLUSIONS This study shows lower freedom from type IB endoleak in the bell-bottom group compared to the standard repair group. There is no significant difference in reoperation rate and 30-day mortality.

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.
