Abstract
Aim The objective of this study is to evaluate the feasibility of using iliac branch endoprosthesis (IBE) devices and to examine their short-term outcomes. Materials and methods This was a descriptive, retrospective observational study involving 15 patients diagnosed with either aortoiliac or isolated iliac artery aneurysms and treated with an IBE device. Data were collected for patients who received IBE devices at Glan Clwyd Hospital in Rhyl, United Kingdom, from February 2020 to May 2023. Results Most patients presented with asymptomatic aneurysms; 86.7% (n = 13) had bilateral common iliac artery (CIA) aneurysms. The mean diameter of the CIA was 38.7 ± 8.8 mm, and the mean diameter of the abdominal aortic aneurysm (AAA) was 39.8 ± 23 mm. For the indications of IBE use, 60% (n = 9) of the patients had iliac aneurysms reaching the intervention threshold, 20% (n = 3) had AAA reaching the threshold, and 20% (n = 3) had aortoiliac aneurysms reaching the threshold. The majority of patients underwent bilateral femoral access (86.7%; n = 13), while 13.3% (n = 2) required both femoral and brachial access. Technical success was achieved in all cases. Aside from 20% (n = 3) of cases where the sac size remained static, the majority of patients (80%; n = 12) experienced sac regression. All patients were free from buttock claudication. A type II endoleak was observed in 33.3% (n = 5) of patients. No reinterventions were reported. The mean primary patency was 30.9 ± 0.7 months, and the follow-up period ranged from 12 to 36 months. Conclusions IBEs are an effective medical device, demonstrating a high rate of technical success, minimal need for additional procedures, and a low incidence of complications while maintaining a satisfactory rate of primary patency.

Eur J Vasc Endovasc Surg 2024; 67:895-902. [PMID: 38320646 DOI: 10.1016/j.ejvs.2024.01.087] [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: 08/21/2023] [Revised: 01/18/2024] [Accepted: 01/30/2024] [Indexed: 02/08/2024]
Abstract
OBJECTIVE Iliac branch devices (IBDs) have shown good results but there is little evidence for the risk of internal iliac artery (IIA) endoleak, so there are no clear recommendations on the maximum diameter it should be. Based on limited evidence, it was hypothesised that an IIA of ≥ 11 mm in diameter presents an increased risk of type Ic endoleak. METHODS This was a single centre, retrospective case control study. Patients undergoing an IBD with the main trunk of the IIA as the target vessel, between 2015 and 2021, were identified. Two groups were created: those with a main trunk diameter of < 11 mm; and those with a diameter of ≥ 11 mm. Technical success, freedom from type Ic endoleak, and re-intervention rates were compared. A receiver operating characteristic (ROC) curve was performed to show a cutoff IIA diameter value for risk of type Ic endoleak. Multivariate analysis was performed to assess the risk of type Ic endoleak and the presence of calcification, stenosis, and landing zone length in the IIA. RESULTS There were 182 IBDs identified. The dilated IIA group (54 IBDs) had significantly lower technical success (91% vs. 98.4%; p = .002), lower freedom from type Ic endoleak (77% vs. 97.1% at 24 months; p = .001), and lower freedom from re-interventions (70% vs. 92.4% at 24 months; p = .002). The ROC curve showed that 10.5 mm was the cutoff diameter for type Ic endoleak. Moderate or severe calcification as well as landing zone length < 5 mm also correlated with type Ic endoleak. CONCLUSION IBDs have a statistically significantly higher rate of technical failure, lower freedom from type Ic endoleak, and lower freedom from re-intervention when the IIA is ≥ 11 mm in diameter.

Abstract
OBJECTIVE The aim of this multicentric registry was to assess the outcomes of "anteRior versus posteRior divisional bRanches Of the hYpogastric artery as distAl landing zone for iLiac branch devices (R3OYAL)." METHODS The main exposure of interest for the purpose of this study was the internal iliac artery (IIA) divisional branch (anterior vs posterior) that was used as distal landing zone. Early endpoints included technical success and adverse events. Late endpoints included survival, primary/secondary IIA patency, and IIA branch instability. RESULTS A total of 171 patients were included in the study, of which 50 received bilateral implantation of iliac branch devices (IBDs). This resulted in a total of 221 incorporated IIAs included in the final analysis, of which 40 were anterior divisional branches and 181 were posterior divisional branches. Technical success was high in both groups (anterior division: 98% vs posterior division: 100%, P = .18). Occurrence of any adverse event was noted in 14% of patients in both groups (P = 1.0). The overall rate of freedom from the composite IBD branch instability did not show significant differences between patients receiving distal landing in the anterior or posterior division of the IIA at 3 years (79% vs 87%, log-rank test = .215). The 3-year estimates of IBD patency were significantly lower in patients who received distal landing in the anterior divisional branch than those who received distal landing in the posterior divisional branch (primary patency: 81% vs 96%, log-rank test = .009; secondary patency: 81% vs 97%, log-rank test < .001). CONCLUSIONS The use of the anterior or posterior divisional branches of the IIA as distal landing zone for IBD implantation shows comparable profiles in terms of immediate technical success, perioperative safety, and side-branch instability up to 3 years. However, IBD patency at 3 years was higher when the distal landing zone was achieved within the posterior divisional branch of the IIA. CLINICAL IMPACT The results from this large multicentric registry confirm that use of the anterior or posterior divisional branches of the internal iliac artery (IIA) as distal landing zone for implantation of iliac branch devices (IBD) shows comparable profiles of safety and feasibility, thereby allowing to extend the indications for endovascular repair of aorto-iliac aneurysms to cases with unsuitable anatomy within the IIA main trunk. Although mid-term rates of device durability and branch instability seem to be similar, the rates of primary and secondary IBD patency at three years was favored when the distal landing zone was achieved in the posterior divisional branch of the IIA.

Abstract
Purpose To determine the efficacy and safety of iliac branch device (IBD) implantation and to evaluate its limitations based on 7 years of experience in a single center. Materials and Methods This single-center study included patients with bilateral common iliac artery aneurysms (CIAAs). We investigated follow-up CT and reviewed the internal iliac artery (IIA) patency and complications related to IBD. A retrospective analysis was performed and the overall survival rate and freedom from reintervention rate were reported according to the Kaplan-Meier method. Results Of the 38 patients with CIAAs, only 10 (12 CIAAs) were suitable for IBD treatment. Five patients underwent unilateral IBD insertion with contralateral IIA embolization, and three (60%) showed claudication; however, symptoms resolved within 6 months. The 7-year freedom from IBD-related reintervention rate was 77.8%. No procedure-related deaths occurred. Conclusion IBD has good technical success and long-term patency rates; however, anatomical factors frequently limit its application, particularly in Asians. Additionally, unilateral IIA embolization showed relatively mild complications and a good prognosis; therefore, it can be performed safely for anatomically complex aortoiliac aneurysms.

Abstract
OBJECTIVE The purpose of this study was to evaluate the technical feasibility, safety, and early outcomes of a snare-less, endovascular abdominal aortic aneurysm repair (EVAR)-first technique (SET) for iliac branch endoprosthesis (IBE) placement. METHODS We retrospectively reviewed all patients who received IBEs between July 2018 and March 2022. Patients were divided into 2 categories based on method of IBE deployment: SET or Standard. Primary endpoints were technical success, major adverse events, mortality, reintervention, internal iliac artery (IIA) patency, and freedom from IIA branch instability. Technical success was defined by successful deployment of both the EVAR and the IBE with maintained patency of the IIA and no stent graft migration. RESULTS There were 20 patients (90% male, median age 72 [65.4-74.5] years) who underwent IBE placement. Among these, 5 (33.3%) underwent SET to treat 5 common iliac artery (CIA)/IIA aneurysms, while the remaining 15 (66.7%) underwent standard IBE deployment with through-and-through femoral access (n=13) or trans-brachial access (n=2) to treat 19 CIA/IIA aneurysms. Overall median renal to iliac bifurcation length was 169 (152-177) mm, with 9 patients falling short of the minimum of 165 mm for on-label IBE placement. Median contrast used was 148 (120-201) mL, fluoroscopy time 42.8 (35.0-49.8) minutes, estimated blood loss 200 (100-275) mL, and procedure time 192 (167-246) minutes, with no significant differences between the 2 groups. Technical success was achieved in 100% of cases. At 30 days, there were no mortalities or major adverse events in either group; there were 100% IIA patency, no IIA instability, and no reinterventions in both groups. Median follow-up in the SET group was 5.7 (5.5-6.2) months, with 1 death at 6 months and 1 type 1B endoleak at 6 months requiring reintervention. Median follow-up for the Standard group was 1.6 (0.8-2.1) years with 2 non-aneurysm-related deaths and no reinterventions at 1 year. CONCLUSIONS SET for IBE is a safe and effective approach that decreases technical complexity and mitigates anatomic barriers to IBE placement. CLINICAL IMPACT SET for IBE is a safe and effective approach to IBE placement that decreases technical complexity. A critical component to this technique is a large bore sheath with a stiff steerable tip. Importantly, this approach also mitigates anatomic barriers to IBE placement, expanding applicability of IBE technology to patients who may be otherwise ineligible.

Abstract
OBJECTIVE The GORE® EXCLUDER® Iliac Branch Endoprosthesis (IBE; W.L. Gore & Associates, Flagstaff, Arizona) was developed to be used in combination with a self-expanding stent graft (SESG) for the internal iliac artery (IIA) bridging stent. Balloon-expandable stent grafts (BESGs) are an alternative for the IIA, offering advantages in sizing, device tracking, precision, and lower profile delivery. We compared the performance of SESG and BESG when used as the IIA bridging stent in patients undergoing EVAR with IBE. METHODS This is a retrospective review of consecutive patients who underwent EVAR with IBE implantation at a single center from October 2016 to May 2021. Anatomic and procedural characteristics were recorded via chart review and computed tomography (CT) postprocessing software (Vitrea® v7.14). Devices were assigned to SESG vs. BESG groups based on the type of device landing into the most distal IIA segment. Analysis was performed per device to account for patients undergoing bilateral IBE. The primary endpoint was IIA patency, and secondary endpoint was IBE-related endoleak. RESULTS During the study period, 48 IBE devices were implanted in 41 patients (mean age 71.1 years). All IBE devices were implanted in conjunction with an infrarenal endograft. There were 24 devices in each of the self-expanding internal iliac component (SE-IIC) and balloon-expandable internal iliac component (BE-IIC) groups. The BE-IIC group had smaller diameter IIA target vessels (11.6±2.0 mm vs. 8.4±1.7 mm, p<0.001). Mean follow-up was 525 days. Loss of IIA patency occurred in 2 SESG devices (8.33%) at 73 and 180 days postprocedure, and in zero BESG devices, however, this difference was not statistically significant (p=0.16). There was 1 IBE-related endoleak requiring reintervention during the study period. A BESG device required reintervention due to Type 3 endoleak at 284 days. CONCLUSIONS There were no significant differences in outcomes between SESG and BESG when used for the IIA bridging stent in EVAR with IBE. The BESGs were associated with using 2 IIA bridging stents and were more often deployed in smaller IIA target arteries. Retrospective study design and small sample size may limit the generalizability of our findings. CLINICAL IMPACT This series compares postoperative and midterm outcomes of self expanding stent grafts and balloon expandable stent grafts (BESG) when used as the internal iliac stent graft as part of a Gore® Excluder® Iliac Branch Endoprosthesis (IBE). With similar outcomes between the two stent-grafts, our series suggests that some of the advantages of BESG, device sizing, tracking, deployment, and profile, may be able to be leveraged without impacting the mid-term performance of the IBE.

Abstract
OBJECTIVE Aneurysmal extension of abdominal aortic aneurysms (AAAs) to the common iliac artery (CIA) presents a technical challenge to successful endovascular abdominal aortic aneurysm repair (EVAR). In the present study, we compared sac shrinkage and perioperative outcomes after the bell-bottom technique (BBT), internal iliac artery embolization and external iliac artery extension (EIE), and iliac branch endoprosthesis (IBE). METHODS Using the Vascular Quality Initiative database, a retrospective analysis was conducted for patients who had undergone EVAR from 2013 to 2019. The demographic, anatomic, and perioperative data were analyzed. All patients with a proximal aortic neck length <10 mm and aortic graft diameter >32 mm were excluded from the analysis. The patients were subdivided into four groups according to the distal limb strategy: group 1, control group with a bilateral common iliac artery limb <20 mm; group 2, BBT with either a unilateral or bilateral limb >20 mm; group 3, EIE technique; and group 4, IBE. The primary endpoint was the maximal change in the aortic diameter during follow-up. The secondary endpoints included postoperative complications and the rate of endoleak. RESULTS The records for 14,455 patients who had undergone EVAR were queried and 5788 met the anatomic criteria. The average age was 73 years, and 86.3% were men. The maximal change in the aortic diameter in the control, BBT, IBE, and EIE groups was -7.2 mm, -6.1 mm, -4.6 mm, and -6.8 mm, respectively (P = .06). The differences were not statistically significant on univariate analysis at an average follow-up of 405 days. However, on multivariable analysis (P = .01), compared with the control group, the BBT and IBE groups were 18.4% (odds ratio [OR], 0.816; 95% confidence interval [CI], 0.68-0.98) and 48.0% (OR, 0.52; 95% CI, 0.33-0.82) less likely to experience aneurysmal shrinkage, respectively. In contrast, the EIE group showed no significant difference in shrinkage compared with that in the control group. Multivariable analysis of the groups also revealed that compared directly with the BBT group, the EIE group was 69.5% more likely to have experienced shrinkage in the aortic aneurysmal diameter (OR, 1.70; 95% CI, 1.05-2.75). The BBT and IBE groups had a significantly higher rate of type II endoleaks (17.63% and 16.95%, respectively; P = .03). The EIE group had a higher rate of type Ib endoleaks (1.9%) compared with the BBT (1.1%), IBE (1.7%), and control (0.3%) groups (P = .01). No differences were found between the groups in terms of postoperative myocardial infarction (P = .47) or respiratory (P = .61) or intestinal (P = .71) complications. However, the rates of limb complications and reoperation were higher in the EIE group. CONCLUSIONS The present study revealed that the EIE technique was more likely to demonstrate shrinkage in the aortic aneurysmal diameter than were the BBT and IBE groups compared with the control group on multivariable analysis. The EIE technique was also more likely to result in aneurysmal sac shrinkage than was the BBT group, albeit with greater rates of limb-related complications.

Abstract
Purpose: To report a novel common-iliac-artery skirt technology (CST) in treating challenge iliac artery aneurysms. Methods: When required healthy landing zone of common iliac artery (CIA) is not available, CST is a strategy to exclude the internal iliac artery (IIA) and prevent IIA reflux without need of embolization. Patients who received endovascular aneurysm repair (EVAR) in our center from 2014 to 2020 were retrospectively screened, and patients treated with CST or with IIA embolization (IIAE) were enrolled. Results: After retrospective screen of 524 EVAR patients, 39 CST patients, 26 IIAE patients, and 7 CST + IIAE patients were enrolled in this study. CST group suggested to have more aged, hyperlipemia, and smoking patients than IIAE group. Two groups had comparable maximal diameter of abdominal aorta (AA), CIA, EIA, but larger diameter of IIA (CST 19.82 ± 2.281 vs. IIAE 27.82 ± 3.401, p = 0.048), and CIA bifurcation (CST 25.01 ± 1.316 vs. IIAE 29.76 ± 2.775, p = 0.087) was found in IIAE group. Anatomy of 79.5% of CST patients and 92.3% of IIAE patients (p = 0.293) was not suitable for potential use of iliac branch device. CST group had significant shorter surgery time (CST 97.42 ± 3.891 vs. IIAE 141.0 ± 8.010, p < 0.001), shorter hospital stay (CST 15.35 ± 0.873 vs. IIAE 19.32 ± 1.067, p = 0.009), lower in-hospital [CST 0% (0/39) vs. IIAE 11.5% (3/26), p = 0.059] and 1-year follow-up stent related MAEs [CST 6.7% (2/30) vs. IIAE 28.6% (6/21), p = 0.052], but comparable mortality and stent related MAEs for all-cohort follow-up analysis comparing to IIAE group. In our study, a lower in-hospital buttock claudication (BC) rate for CST (CST 20.5% vs. IIAE 46.2%, p = 0.053) and a comparable erectile dysfunction (ED) rate (CST 10.3% vs. IIAE 23.1%, p = 0.352) were found between CST and IIAE groups. After 1 year, both groups had about one third relief of BC symptoms [CST 33.3% (4/12) vs. IIAE 30.7% (4/13), p = 1.000]. Subgroup analysis of 14 patents concomitant with IIA aneurysm in CST group and the 7 CST + IIAE patients were carried out, and no difference was found in mortality, stent MAEs, sac dilation, or reintervention rate. Last, illustration of seven typical CST cases was presented. Conclusion: In selected cases, the CST is a safe, feasible-and-effective choose in treating challenge iliac artery aneurysms and preventing IIA endoleak.

Abstract
BACKGROUND Internal iliac artery aneurysms (IIAA) are uncommon. Open repair is technically challenging and has been associated with increased morbidity and mortality compared with repair of abdominal aortic aneurysms. The aim of this study is to assess the outcomes of endovascular treatment of IIAA and incidence of postoperative pelvic ischaemia. METHODS A single-centre retrospective analysis was performed for IIAAs treated with endovascular repair between January 2005 and December 2017. Aneurysm morphology, mode of presentation and operative technique were evaluated. Primary outcomes were 30-day mortality and incidence of pelvic ischaemia. Secondary outcomes were technical success, major complications and reintervention. RESULTS Twenty-nine IIAAs were treated in 23 patients with a mean age of 74 */- 9 years. Six patients had isolated IIAAs (26%); the remaining 17 patients had aortoiliac aneurysms. Five patients (22%) required emergent repair for ruptured IIAAs. Mean IIAA size was 4.1 cm */- 1.8 and ruptures occurred at mean 6.1 cm */- 2.6. Endovascular techniques used: stent graft occlusion of the internal iliac artery (IIA) ostium (n = 16), deployment of iliac branch device (n = 9), and other endovascular techniques (n = 4). The 30-day mortality was zero. Three patients (13%) experienced post-operative pelvic ischemia which were all minor chronic gluteal claudication after IIA occlusion. Primary technical success was achieved in 27 repairs (93%). There was one late reintervention (3%). CONCLUSION IIAAs are often asymptomatic and diagnosed incidentally, however, a significant proportion present emergently. Endovascular treatment is feasible for both ruptured and non-ruptured aneurysms with low perioperative morbidity, mortality and reintervention rates.

Ann Vasc Surg 2021; 77:38-46. [PMID: 34455041 DOI: 10.1016/j.avsg.2021.05.065] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Revised: 05/08/2021] [Accepted: 05/31/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Endovascular treatment of complex common iliac artery (CIA) and internal iliac artery (IIA) aneurysms using iliac branch endoprostheses (IBE) has proven safe and effective. Instructions for use (IFU) require deployment of current IBE technology with the corresponding manufacturer's modular bifurcated aortic endograft. Concomitant aortoiliac occlusive disease, inadequate renal artery-iliac bifurcation length, and unfavorable aortic anatomy preclude on-label IBE deployment. This study aimed to evaluate the technical feasibility and safety of Alternative Endograft Aortoiliac Reconstruction (AEGAR) for branched endovascular treatment of complex iliac artery aneurysms. METHODS In 7 consecutive patients with CIA or IIA aneurysms, computed tomography angiography (CTA) and center-line reconstruction revealed aortoiliac anatomy incompatible with the current IBE IFU due to inadequate proximal CIA landing zone (n = 7), inadequate renal artery to iliac bifurcation length (n = 2), compromised aortic anatomy (n = 3), or short infrarenal neck <15 mm (n = 1), either alone or in combination. To overcome these restrictions and facilitate IBE deployment, aortoiliac reconstruction was performed using the Endologix AFX, Endologix Ovation limbs or the Medtronic Endurant II platforms (AEGAR technique). All internal iliac artery reconstructions and external iliac artery extensions were performed using the Gore VBX or Viabahn stent grafts. Technical success was defined as successful delivery of all endograft components without migration or endoleak. RESULTS The mean patient age was 69 years (range 52-82 years; 6 male). Four patients had bilateral CIA aneurysms and 3 patients had unilateral CIA aneurysms (mean diameter 4.3cm; range 2.2-7 cm). There were 13 IIA VBX stent grafts used for a total of 9 IIAs treated with IBE (bilateral IBE = 2 patients). The mean fluoroscopy time was 38.8 min (range 21.3-64.3 min) and the mean contrast volume was 168.5 mL (range 122-226 mL). Technical success was achieved in all patients and there were no perioperative complications. Mean hospital-stay was 2.2 days (range 1-3 days). Follow-up ranged from 82-957 days (mean = 487 days). At last follow-up, all patients were alive without cardiovascular morbidity; and CTA revealed stable or decreased aneurysm size, patent endografts, and no evidence of endoleak or migration. CONCLUSIONS The AEGAR technique can be used to safely and effectively overcome certain aortoiliac anatomic constraints that preclude use of current IBE technology. We encourage broader use of these alternative endografts in pertinent anatomic configurations.

Outcomes after Standalone Use of Gore Excluder Iliac Branch Endoprosthesis for Endovascular Repair of Isolated Iliac Artery Aneurysms. Ann Vasc Surg 2020; 67:158-170.

Abstract
BACKGROUND The aim of our study was to describe outcomes of stand-alone use (i.e., without concomitant implantation of an aortic stent graft) of the Gore Excluder iliac branch endoprosthesis (IBE) for elective endovascular repair of isolated iliac artery aneurysms. METHODS We evaluated all consecutive patients electively treated for isolated iliac artery aneurysms using standalone Gore Excluder IBE (January 2014-December 2018). Early (i.e., 30-day) endpoints were technical success, mortality, major adverse events (MAEs), and major access-site complications. Late endpoints were survival, freedom from aortic-related mortality (ARM), internal iliac artery (IIA) primary patency, IIA branch instability, graft-related adverse events (GRAEs), secondary interventions, endoleaks (ELs), aneurysm sac behavior, and new-onset buttock claudication (BC). RESULTS A total of 11 consecutive patients (10 men; median age 75 years) were included. The technical success rate was 100%. At 30 days, mortality, MAEs, and major access-site complications were all 0%. Survival and freedom from ARM were 91% and 100%, respectively; only one nonaortic related death was recorded during follow-up. At a median follow-up of 14 months, IIA primary patency, IIA branch instability, and GRAEs were 100%, 0%, and 0%, respectively. No instances of graft migration ≥10 mm were detected. No graft-related secondary interventions were recorded, and 2 patients required a procedure-related secondary intervention 3 months after the index procedure (1 common femoral artery endarterectomy and 1 external iliac artery stenting). Although new-onset type 1 or type 3 ELs were never noted, one patient developed a new-onset type 2 EL. Aneurysm sac regression ≥5 mm was noted in 6 patients (55%), whereas in the remaining ones, the sac size was stable. No instances of new-onset BC were noted. CONCLUSIONS Use of standalone Gore Excluder IBE for elective endovascular repair of isolated iliac artery aneurysms is a safe, feasible, and effective treatment option. These results may support use of the technique as an effective means of endovascular reconstruction in patients with suitable anatomy.

Abstract
Purpose: To evaluate the outcomes of the Gore Excluder Iliac Branch Endoprosthesis (IBE) using division branches of the internal iliac artery (IIA) as distal landing zones. Materials and Methods: Between January 1, 2014, and December 31, 2018, 74 patients (mean age 74±7 years; 72 men) treated for aortoiliac or common iliac artery aneurysms had an IBE deployed with distal landing of the side branch within the main trunk (n=60) of the internal iliac artery (IIA) vs within a division branch (n=25). Thirteen (17%) patients received bilateral IBE implantations for a total of 85 vessels evaluated. Early endpoints were technical success, 30-day mortality, 30-day major adverse events (MAEs), and 30-day major access complications. Late endpoints were survival, primary and secondary IIA patency, freedom from IIA branch instability, freedom from new-onset buttock claudication, and aneurysm sac diameter changes. Time-dependent outcomes were reported as Kaplan-Meier curves with differences assessed using the log-rank test. Estimates are presented with the 95% confidence interval (CI). Results: The overall technical success rate was 97%, with 1 technical failure per group (p=0.43). Two patients, one from each group, died within 30 days (p=0.43). No significant differences were seen in the rates of 30-day MAEs (7% vs 17%, p=0.35) or major access complications (9% vs 11%, p>0.99) for patients receiving distal landing in the main trunk vs a division branch, respectively. The mean follow-up for the entire cohort was 19±12 months. The overall 1-year survival rate was 94% (95% CI 74% to 99%). The primary and secondary patency rates at 1 year were 98% (95% CI 88% to 99%) vs 95% (95% CI 72% to 99%, p=0.72) and 98% (95% CI 88% to 99%) vs 100% (p=0.41) for the main trunk vs division branch groups, respectively. Freedom from IIA branch instability estimates were also similar at 1-year follow-up [93% (95% CI 82% to 97%) vs 90% (95% CI 66% to 97%), p=0.29], as were the freedom from new-onset buttock claudication estimates [98% (95% CI 86% to 99%) and 94% (95% CI 67% to 99%), respectively; p=0.62]. Mean sac diameter change was 5.4±5.3 mm, not significantly different between the groups (p=0.85). Conclusion: Use of the posterior or anterior division of the IIA as a distal landing zone for the Gore Excluder IBE was safe and efficacious in the midterm. This technique may permit extending indications for endovascular repair of aortoiliac aneurysms to cases with unsuitable anatomy within the IIA main trunk. Long-term assessment is needed to affirm the efficacy of this technique.

Abstract
INTRODUCTION The feasibility of endovascular aneurysm repair (EVAR) is often challenged by the concurrent presence of common iliac artery aneurysms, which prevent the attainment of a successful distal sealing. The present review aims to portray the safety and efficacy of two internal iliac artery (IIA) preservation strategies in the endovascular treatment of aortoiliac aneurysms: the iliac branch extension device (IBED) and the parallel graft - "sandwich" technique (PG-ST). EVIDENCE ACQUISITION A comprehensive literature review was conducted to identify publications on endovascular treatment of iliac aneurysmal disease using IBED or PG-ST. Primary endpoints were freedom from endoleak, IIA branch occlusion and secondary interventions. EVIDENCE SYNTHESIS Twenty-eight studies were selected for analysis describing a total of 1316 patients, 1169 in the IBED group and 147 in the PG-ST group. The technical success rates were akin for IBED and PG-ST (83.9-100% versus 81.3-100%). The defined primary endpoints were reported by fourteen articles. Freedom from endoleak, IIA branch occlusion and reintervention, at 6 months, were as follows: 82-100% versus 86%, 90-94% versus 88%, and 90-98% versus 87%, respectively for IBED and PG-ST. Later outcomes were only recorded in the IBED group, and freedom from endoleak, IIA branch occlusion and reintervention, at 9 years, were 83%, 81-90%, and 64-75%, respectively. CONCLUSIONS Both IBED and PG-ST have proven to be safe and valid approaches. However, while IBED has established as a durable procedure, mid-term data lacks on PGs performance and further studies are required to attest durability of the latter procedure.

Abstract
BACKGROUND Sacrifice of the internal iliac artery (IIA) may result in ischemic manifestations after aortoiliac aneurysm (AIA) or common iliac artery aneurysm (CIAA) endovascular repair. This study sought to evaluate the safety and efficacy of a new Iliac Bifurcation Stent Graft (IBSG; Lifetech Scientific, Shenzhen, China) system for revascularization of the IIA. METHODS Patients who underwent implantation of the IBSG at 8 centers in China from September 2015 to June 2018 were enrolled. Clinical and computed tomography angiography follow-up assessments were conducted at 30 and 180 days postoperatively. The primary end point was the IIA patency rate of the IBSG device at 180 days postoperatively. Secondary end points comprised the postoperative technical success rate and clinical success rate at 30 and 180 days. Descriptive statistics and the Clopper-Pearson exact method were used to analyze the data. RESULTS Seventy-three patients (mean age, 69.6 years; 91.8% men) were eligible for this trial, and 59 patients were eligible for primary effectiveness end-point analysis. AIA was present in 55 patients (75.34%) and CIAA in 18 patients (24.66%). The iliac artery aneurysms were unilateral in 69 patients (94.52%) and bilateral in 4 patients (5.48%). Overall technical success was 89.04% (65 of 73 patients). IIA patency at 180 days was 96.61% (57 of 59 patients). Sexual dysfunction occurred in 1 patient (1.69%), and 2 patients (3.39%) experienced buttock claudication. There was no mortality, type III endoleak, stent migration, kinking, or fracture during the procedure and follow-up. CONCLUSIONS The IBSG implantation system is a safe and effective technique for IIA preservation during AIA or CIAA endovascular repair. The high technical success rate, IIA patency rate, and low complication rate are promising. Follow-up will be continued for 5 years to confirm the durability of the device.

Abstract
BACKGROUND Endovascular repair with stent-graft is a treatment option for patient with common iliac artery aneurysm (CIAA). However, the preservation of the internal iliac artery (IIA) is a concern. The commercially available iliac branched device (IBD) requires a common iliac length of at least 5 cm, which is usually too long for Asian people. Here, we report our medium-term results of using tailor-made IBD for patients with short common iliac artery (CIA) with and without abdominal aortic aneurysm (AAA). METHODS A selected iliac limb of the AAA stent-graft was unloaded from the delivery system. A 6-mm fenestration hole was made at the length of the CIA from the proximal end. The edge of the hole was reinforced with the soft and radiopaque tip of a 0.014´´ wire. Then, the iliac limb was reloaded into the introduced sheath as the tailor-made IBD. It was inserted from the selected side of the femoral artery and deployed. The ipsilateral IIA was cannulated through the fenestration hole. Then, a balloon-expandable or self-expandable covered stent with an appropriate size was deployed as the bridging stent-graft. RESULTS Between March 2013 and March 2017, a total of 10 patients received the tailor-made IBDs. One patient died of systemic thromboembolism 2 days after the operation. The bridging stent-grafts remained patent in all patients, except one occluded at 1 year after operation. CONCLUSION A tailor-made IBD is an easy-to-apply, alternative option for preserving the IIA perfusion in short CIAA patients with and without AAA.

Abstract
The purpose of this article is to describe the techniques used to deploy a Gore® Excluder® abdominal aortic aneurysm (AAA) and iliac branch endoprosthesis (IBE) in a short aortoiliac anatomy, expanding treatment options of a patient otherwise unfit for endovascular repair. Four strategies were used to shorten the total length of the components, achieving a reduction of over 3 cm during deployment: a pull-pull technique on a through-and-through guidewire to accommodate the IBE onto the iliac bifurcation, deployment in a "cross-limb" configuration, foreshortening of the iliac bridging component during release, and final proximal shortening of the AAA main body thanks to the C3 repositionable delivery system.

Abstract
In conjunction with traditional modular bifurcated aortic endografts, bilateral iliac branch endoprostheses have been safely and effectively used for treatment of bilateral iliac artery aneurysms. However, anatomic constraints, such as inadequate renal artery to iliac bifurcation lengths and unfavorable aortic anatomy, can preclude deployment in certain configurations and limit use in many patients. We present an innovative technique to overcome such anatomic constraints and to extend the reach of iliac branch endoprosthesis technology in patients with iliac artery aneurysms.

Abstract
OBJECTIVE Internal iliac artery aneurysm (IIAA) is a rare entity. Its treatment can be technically challenging. The aim of this study was to evaluate the treatment possibilities in an era of advanced endovascular techniques and their potential to preserve iliac blood flow while reliably excluding the aneurysm. METHODS A retrospective analysis of 46 consecutive patients with endovascularly treated IIAA was performed. Data were collected from a single-institution aortoiliac database. The following end points were recorded: technique of aneurysm exclusion, technical success rates, perioperative morbidity and mortality, primary patency, and midterm follow-up. RESULTS Between September 2009 and May 2016, a total of 46 patients with 55 IIAAs were identified. The majority of patients (n = 39 [84.8%]) had aortoiliac aneurysms and seven had isolated IIAAs (15.2%). The following surgical techniques were used: implantation of iliac branch devices (IBDs; n = 29), occlusion of the internal iliac artery (IIA) by ostium coverage with or without prior coil embolization (n = 23), and other endovascular techniques (n = 3). Primary assisted technical success was achieved in 93.1% of IBD implantations and in 100% of occlusions by ostium coverage and other techniques. Overall 30-day mortality was 4.3% (n = 2) and 0% in electively treated patients. Assisted midterm patency after IBD implantation was 93.1%. Gluteal claudication occurred in seven patients (15.2%) who had undergone intentional or accidental occlusion of the IIA or the superior gluteal artery. Reintervention rates within the midterm follow-up were 13.8% (n = 4) after IBD implantation and 4.3% (n = 1) after coverage of the IIA ostium. No ruptures were observed during follow-up, and no complications occurred during reinterventions. CONCLUSIONS Implantation of IBD devices for the treatment of hypogastric artery aneurysms shows good technical results with a high primary patency and a low rate of perioperative complications. Although successful aneurysm exclusion while preserving pelvic blood flow is associated with a higher rate of reinterventions during midterm follow-up, it should be taken into consideration, especially in complex endovascular aortoiliac aneurysm repair.

Abstract
The advent of endovascular technology for treating aortoiliac aneurysms has sometimes necessitated the occlusion of the hypogastric artery to prevent an endoleak or to achieve an adequate distal seal, resulting in significant morbidity for some patients. The use of iliac branch devices, in conjunction with aortic stent grafts, has made it possible to preserve the hypogastric arteries in select patients with suitable anatomy. The purpose of this review will be to discuss the indications for hypogastric preservation during treatment of aortoiliac aneurysms, as well as highlight the key procedural steps and potential technical challenges encountered during this procedure.

Abstract
BACKGROUND The iliac side branch device (IBD) is a valid method for the treatment of abdominal aorto-iliac aneurysms. However there is still a lack of evidence regarding the optimal length of the bridging stent graft (BSG) since aneurysmal degeneration of the hypogastric artery (HA) is an exclusion criterion. The aim of this study was to analyse the impact of longer BSG compared to the widely used 38mm stent-grafts in terms of reintervention rate and primary patency. METHODS We retrospectively analyzed our prospectively collected database of all patients who underwent an endovascular aneurysm repair using an IBD in our center between April 2005 and May 2015. The used BSGs were divided into 2 groups. In group A, the BSG was ≤38 mm, and group B>38 mm. The primary endpoint was BSG-related events, including stenosis, occlusion or endoleak. Secondary endpoints were technical success, primary patency and 30-day mortality. RESULTS Two hundred sixty IBDs were implanted in 215 consecutive patients. Ninetyseven (37%) in group A and 163 (63%) in group B. The technical success rate was 100%. The 30-day mortality was 1% (N.=1) and 1.2% (N.=2) respectively for group A and B (P=0.8). The freedom from BSG-related events amounted to 84% at 60 months for the total cohort. The comparison between the two groups shows no significant difference, while a slight favorable trend for group B (75% vs. 91% at 60 months, P=0.081) was observed. No differences were found as to primary patency (96% and 99% at 60 months respectively for group A and B, P=0.237). CONCLUSIONS The use of longer stent-grafts (>38 mm) seems not to affect the performance of BSG even in the long run, expanding the indication for IBD also for aneurysms of the hypogastric artery.

Abstract
BACKGROUND Bell-bottom technique (BBT) is one method to preserve the internal iliac artery during endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) that extends to iliac artery. The data on the efficacy of this technique are still limited. We sought to evaluate the midterm efficacy of BBT by using different stent grafts in the treatment of AAA combined with iliac artery aneurysm (IAA). METHODS From January 2011 to December 2016, AAA patients with IAA using BBT to preserve the internal iliac artery were retrospectively analyzed in our institution. Patients were followed up at 3, 6, and then every 12 months after surgery. The outcomes among 3 types of stent grafts (Zenith, Excluder, and Endurant) were compared. BBT-related end points including type Ib endoleak, IAA sac expansion, distal neck expansion, and rupture during follow-up were compared. Other events including perioperative death, any other types of endoleak, and corresponding management were also documented. RESULTS A total of 125 patients with 141 IAAs were identified. Ninety-eight patients (78.4%) with 113 lesions (80.4%) received a median follow-up time of 38 months. The incidence of type Ib endoleak was 22.9%, 8.3%, 11.9%, and 14.2% (P = 0.19) in Zenith, Excluder, Endurant group, and total patients, respectively. The incidence of IAA sac enlargement was 17.1%, 5.6%, 7.1%, and 9.7% (P = 0.20). The incidence of IAA rupture was 8.6%, 0.0%, 0.0%, and 2.7% (P = 0.03). The incidence of IAA neck enlargement was 34.3%, 13.9%, 16.7%, and 21.2% (P = 0.07). Totally, 14 cases (10.7%) received further treatment for BBT-related issues. CONCLUSIONS Although BBT remains a safe and effective treatment option to preserve internal iliac artery during standard EVAR with acceptable complication rates in Asians, different IAA rupture rates were found among 3 different stent grafts. Our data for the first time revealed that the type of stent grafts has influence on the final clinical outcome. Based on that, iliac extension should be selected appropriately while treating AAA-IAA.

Abstract
About 20% of patients with abdominal aortic aneurysms have associated iliac aneurysms. Distal sealing during the endovascular treatment of aortic-iliac aneurysms is a challenge that has led to the emergence of several technical options to achieve this goal over the years. Internal iliac artery embolization is associated with the risk of ischemic complications, such as gluteal necrosis, lower limb neurological deficit, colonic ischemia, impotence and gluteal claudication. This article summarizes the technical options for endovascular treatment of aortoiliac aneurysms with different approaches to preserving the patency of internal iliac arteries.

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
BACKGROUND Understanding that the common iliac arteries (CIA) are shorter in Asian patients, we investigated whether this anatomic difference affects the clinical outcomes of internal iliac artery (IIA) exclusion during endovascular aneurysm repair (EVAR) of aortoiliac aneurysm and thus limits the use of IIA-preserving devices in Japanese patients.Methods and Results:From 2008 to 2014, 69 Japanese patients underwent EVAR of aortoiliac aneurysms with 53 unilateral and 16 bilateral IIA exclusions. One patient had persistent buttock claudication during follow-up; however, colonic or spinal cord ischemia was not observed. Anatomic suitability was investigated for the iliac branch device (IBD) by Cook Medical and the iliac branch endoprosthesis (IBE) by WL Gore: 87 aortoiliac segments were analyzed, of which 17% met the criteria for the IBD, 25% met the criteria for the IBE and 40% met the criteria for either. Main exclusions for the IBD were IIA diameter >9 mm or <6 mm (47%) and CIA length <50 mm (39%). Main exclusions for the IBE were proximal CIA diameter <17 mm (44%) and aortoiliac length <165 mm (24%). CONCLUSIONS EVAR with IIA exclusions in Japanese patients showed low incidence of persistent buttock claudication and no major pelvic complications. Aorto-iliac morphology demonstrated smaller proximal CIA diameters and shorter CIA lengths, limiting the use of IIA-preserving devices.

Abstract
Purpose: To evaluate the efficacy, feasibility, and long-term outcomes of the Zenith ZBIS iliac branch device (IBD) to preserve internal iliac artery (IIA) perfusion in a large Dutch multicenter cohort. Methods: Between September 2004 and August 2015, 140 patients (mean age 70.9±7.4 years; 130 men) with 162 IBD implantations were identified in 7 vascular centers. The indication for IBD implantation was an abdominal aortic aneurysm >55 mm with a concomitant common iliac artery (CIA) aneurysm >20 mm (n=40), a CIA aneurysm with a diameter >30 mm (n=89), or revision of a type Ib endoleak after endovascular aneurysm repair (n=11). Results: Technical success (aneurysm exclusion, no type I or III endoleak, and a patent IIA) was obtained in 157 (96.9%) of 162 IBD implantations. Six (4.3%) patients developed major complications; 2 (1.4%) died. Mean follow-up was 26.6±24.1 months, during which 17 (12.1%) IBD-associated secondary interventions were performed. Including technical failures and intentional IIA embolizations, 15 (9.3%) IIA branch occlusions were identified; buttock claudication developed in 6 of these patients. The freedom from secondary intervention estimate was 75.9% (95% confidence interval 59.7 to 86.3) at 5 years. Conclusion: CIA aneurysms can be treated safely and effectively by IBDs with preservation of antegrade flow to the IIA. Secondary interventions are indicated in >10% of patients during follow-up but can be performed endovascularly in most.

Abstract
Endovascular repair of abdominal aortic aneurysms is an important technique in the vascular surgeon's armamentarium, which has created a seismic shift in the management of aortic pathology over the past two decades. In comparison to traditional open repair, the endovascular approach is associated with significantly improved perioperative morbidity and mortality. The early survival benefit of endovascular abdominal aortic aneurysm repair is sustained up to 3 years postoperatively, but longer-term life expectancy remains poor regardless of operative modality. Nonetheless, most abdominal aortic aneurysms are now repaired using endovascular stent grafts. The technology is not perfect as several postoperative complications, namely endoleak, stent-graft migration, and graft limb thrombosis, can develop and therefore lifelong imaging surveillance is required. In addition, a postoperative inflammatory response has been documented after endovascular repair of aortic aneurysms; the clinical significance of this finding has yet to be determined. Subsequently, the safety and applicability of endovascular stent grafts are likely to improve and expand with the introduction of newer-generation devices and with the simplification of fenestrated systems.

Abstract
We evaluated the outcome of the retrograde endovascular hypogastric artery preservation (REHAP) technique for the treatment of complex aortoiliac aneurysms (AIAs). Perioperative and long-term outcomes were assessed for 12 patients (mean age 77 years, range 64-86 years) who underwent elective endovascular AIA repair via aortouniiliac endografting and REHAP between January 2004 and January 2011. Preoperative images obtained by computed tomography were used for planning. Postoperative images were obtained one and six months after surgery, and once a year thereafter. Technical success was achieved in all cases. No patients exhibited endoleak related to the endoprosthesis, occlusion of implanted components, hip and/or buttock claudication, or colon or spinal cord ischemia during follow-up. This hybrid procedure illustrates the potential of REHAP in the treatment of AIA cases.

Abstract
The morphology of infrarenal abdominal aortic aneurysms (AAAs) directly influences the perioperative outcome and long-term durability of endovascular aneurysm repair. A variety of methods have been proposed for the characterization of AAA morphology using reconstructed three-dimensional (3D) computed tomography (CT) images. At present, there is lack of consensus as to which of these methods is most applicable to clinical practice or research. The purpose of this review was to evaluate existing protocols that used 3D CT images in the assessment of various aspects of AAA morphology. An electronic search was performed, from January 1996 to the end of October 2010, using the Embase and Medline databases. The literature review conformed to PRISMA statement standards. The literature search identified 604 articles, of which 31 studies met inclusion criteria. Only 15 of 31 studies objectively assessed reproducibility. Existing published protocols were insufficient to define a single evidence-based methodology for preoperative assessment of AAA morphology. Further development and expert consensus are required to establish a standardized and validated protocol to determine precisely how morphology relates to outcomes after endovascular aneurysm repair.

Abstract
PURPOSE To attempt to quantify the effect of varying degrees of iliac tortuosity on maneuverability and "torquability" of endovascular catheters in the visceral segment, comparing conventional and robotic cannulation techniques. MATERIALS AND METHODS In a fenestrated endograft within a pulsatile phantom, 10 experienced operators cannulated the renal arteries via three different access vessels of varying iliac tortuosity with the use of conventional and robotic techniques. All procedures were performed in the angiography suite and recorded for blinded video assessment for quantitative (time, catheter-tip movements) and qualitative metrics (operator performance scores). RESULTS In total, 120 cannulations were observed. With increasing iliac tortuosity, median time and number of catheter movements required for renal cannulation with conventional techniques increased in stepwise fashion for mild, moderate, and severe iliac tortuosity (times, 7.6 min [interquartile range (IQR), 4.6-9.3 min] vs 6.9 min [4.2-11.4 min] vs 17.7 min [13.3-22.6 min], respectively; movements, 184 [IQR, 110-351] vs 251 [207-395] vs 569 [409-616], respectively). Median renal cannulation times were significantly reduced with the use of the robotic system irrespective of mild, moderate, or severe tortuosity (times, 1.4 min [IQR, 1.1-1.9 min] vs 3 min [2.3-3.3 min] vs 2.8 min [1.5-3.9 min], respectively; movements, 19 [IQR, 14-27] vs 46 [43-58] vs 45 [40-66], respectively; P < .005). Overall operator performance scores improved significantly with the use of the robotic system irrespective of iliac tortuosity severity. CONCLUSIONS In cases of moderate to severe iliac tortuosity, conventional catheter manipulation and control becomes an issue. The improvement in positional control and predictability seen with advanced catheter designs may be amplified in cases of severe iliac tortuosity.
