Abstract
INTRODUCTION The distal landing zone in iliac arteries represents an important issue during endovascular repair of abdominal aortic aneurysms (EVAR). The aim of this study is to present a case series for landing in the external iliac artery (EIA) during EVAR while preserving blood flow in the internal iliac artery (IIA) with the covered endovascular reconstruction of the iliac bifurcation (CERIB) technique. METHODS This is a single-center, retrospective analysis of prospectively collected data of patients that underwent EVAR either for intact abdominal aortic aneurysm (AAA) or previous failed EVAR from December 2022 up to September 2023. Indications for treatment were presence of common iliac artery aneurysm (CIAA), short CIA, or endoleak type Ib (ETIb). For the distal sealing zone, we used balloon-expandable covered stent (BXCS). Primary outcomes were technical success and first-month patency rate. Secondary outcomes were endoleak and re-intervention rate. RESULTS Sixteen patients being treated with 20 CERIBs were included in the study. Four patients had a previous failed EVAR, while 3 patients were treated urgently for a symptomatic para-renal aneurysm. The indications for treatment were EIb (n=2), short CIA (n=4), CIAA with narrow lumen (n=3), and CIA aneurysm (n=11). Platforms that were used were the Cook Zenith Alpha (n=5), Gore C3 (n=2 and 3 limbs), Endurant IIs (n=2, and 3 limbs), and a t-branch device (n=3). Technical success rate was 100% with no adjunctive procedure. No death or re-intervention was recorded for all patients at postoperative 30-day period and at 6 months for 2 patients. At first-month CTA, patency rate was 100% (20/20), while in 2 patients that had 6-month CTA, the patency was also 100% (2/2). No kinking or stenosis was also noted. Two patients had ETIII after branched EVAR (BEVAR), 2 patients had ETII, and 1 patient had gutter ET in the area of the CERIB. CONCLUSION The CERIB technique seems to be effective and safe in the early period. It is suitable with a variety of commercial endograft platforms. It may be a valuable alternative to iliac branch devices when there are anatomical considerations. Longer follow-up is needed to conclude for long-term patency and durability. CLINICAL IMPACT The distal landing zone in iliac arteries represents an important issue during EVAR while it is important to preserve blood flow in the internal iliac artery. The covered endovascular reconstruction of the iliac bifurcation (CERIB) technique is a technique for the preservation of internal iliac arteries during EVAR, while it is suitable with a variety of commercial endograft platforms. The CERIB technique seems to be effective and safe in the early period. It may be valuable alternative to iliac branch devices when there are anatomical considerations.

Hospital Incidence and Treatment Outcomes of Patients with Aneurysms and Dissections of the Iliac Artery in Switzerland-A Secondary Analysis of Swiss DRG Statistics Data. J Clin Med 2024; 13:2267. [PMID: 38673541 PMCID: PMC11051054 DOI: 10.3390/jcm13082267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 04/11/2024] [Accepted: 04/12/2024] [Indexed: 04/28/2024] Open
Abstract
Background/Objectives: Aneurysms and dissections of the iliac artery (ADIAs) are significant vascular conditions often associated with aortic pathologies. Despite their importance, reports on isolated iliac artery pathologies are rare. This study aimed to investigate the epidemiology of ADIA in Switzerland including treatment incidence and hospital outcomes. Methods: A retrospective analysis of diagnosis-related group (DRG) statistics from 2011 to 2018 in Switzerland was conducted, identifying all cases of ADIA while excluding those with concomitant treatment of aortic pathologies. Age-standardized incidence rates and treatment outcomes were assessed, with multivariable logistic regression performed to identify factors associated with hospital mortality. Results: From 2011 to 2018, 1037 ADIA cases were hospitalized in Switzerland. Incidence rates for elective treatment were significantly higher in men than women, increasing in men from 1.5 to 2.4 cases per 100,000 men (p = 0.007), while remaining stable in women at around 0.2 cases per 100,000 women. Acute treatment incidence rates were lower but still higher in men, at 0.9 cases per 100,000 men and 0.2 cases per 100,000 women. Crude hospital mortality rates were lower for endovascular repair than open surgical repair in both elective (0.8% vs. 3.1%, p = 0.023) and emergency treatment (6.7% vs. 18.4%, p = 0.045). Multivariable analysis showed that endovascular repair was associated with significantly reduced hospital mortality compared to open repair (OR 0.27, 95%-CI: 0.10 to 0.66, p = 0.006). Conclusions: This nationwide study of iliac artery pathologies shows that the treatment incidence was about 10 times higher in men than in women for elective procedures, but only about five times higher for emergency treatment. Endovascular procedures were associated with significantly lower hospital mortality than open procedures, while hospital mortality rates were comparable for men and women.

Mid-Term Outcomes of a Pre-Cannulated Iliac Branched Device in the Treatment of Abdominal Aortoiliac Aneurysms: A Retrospective Analysis from a Single Center. J Clin Med 2023; 12:6395. [PMID: 37835039 PMCID: PMC10573636 DOI: 10.3390/jcm12196395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Revised: 10/03/2023] [Accepted: 10/06/2023] [Indexed: 10/15/2023] Open
Abstract
The aim was to assess the mid-term results of the E-iliac branched device. Baseline and follow-up data of this monocentric retrospective cohort study including all consecutive patients with aortoiliac aneurysms treated with iliac branched devices between 2016 and 2023 were extracted from the hospital records. Preoperative and follow-up CT scans were analyzed regarding endoleaks, migration, aneurysm sac remodeling, and device patency. Overall, 50 devices were implanted in 38 patients with a median age of 69 (IQR 62-78) years, and 1.6 bridging stent grafts per vessel were implanted through transfemoral (22/50; 44%) or upper extremity access (28/50; 56%). Primary technical success and assisted technical success were 97% (37/38) and 100% (38/38), respectively. No migration, no type I or III endoleaks, no stroke, colonic ischemia, aneurysm rupture, or conversion during the early and mid-term follow-ups (11 months, IQR 5-26) were observed. Aneurysm sac enlargement or shrinkage was observed in 0% (0/38) and 16% (6/38) patients, respectively. E-iliac-related re-interventions were seen only during the early follow-up: two thrombectomies with bare-metal stent relining after thrombosis of the iliac limb. Bridging stent graft and E-iliac patency during the mid-term follow-up were 100%. E-iliac showed encouraging mid-term results in the treatment of aortoiliac aneurysms with high technical success and a low re-intervention rate.

Abstract
OBJECTIVE The aim of this multicentric study was to assess the "REsults of iliac branch deviceS for hypogastriC salvage after previoUs aortic rEpair (RESCUE)." METHODS All consecutive patients who underwent implantation of iliac branch devices (IBDs) after previous open aortic repair (OAR) or endovascular aortic repair (EVAR) at seven centers were captured. The study cohort was divided into two groups according to the type of repair originally performed. Early outcomes included immediate technical success and perioperative adverse events. Late outcomes included survival, side branch (SB) primary patency, SB instability, and new onset buttock claudication. RESULTS A total of 94 patients (82 male) were included in the study, 10 of them received bilateral implantation of IBDs. This resulted in a total of 104 devices included in the final analysis. Indication for treatment were endoleak 1b or progressive iliac aneurysmal degeneration or distal para-anastomotic aortic aneurysms; 73 were implanted after previous EVAR and 31 after previous OAR. Technical success was 100% in both groups. The 3-year rate of freedom from SB instability was 90.1% after previous EVAR and 85.4% after previous OAR, respectively (P = .05). The 3-year estimates of SB primary patency were significantly lower in patients who had received OAR as compared with those that had received EVAR (89.8% vs 94.9%; P = .05). CONCLUSIONS Endovascular treatment with IBDs following previous OAR or EVAR is safe and effective up to 3 years. Freedom from SB instability during follow-up was lower in patients who had previously undergone OAR than EVAR.

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 To assess the safety and effectiveness of iliac branch devices (IBDs), as secondary procedure, for the treatment of type Ib endoleak or evolution of iliac artery disease after prior endovascular aortic repair (EVAR) for thoraco-abdominal (TAAAs) or abdominal aortic aneurysms (AAAs). METHODS A multicentre observational study of three European centres. The study included 75 patients (age 71 ± 9 years, 96% men) with previous EVAR (n = 64, 85%) or fenestrated or branched (FB) EVAR (n = 11, 15%). Overall, 88 IBDs were implanted to treat aneurysmal iliac artery evolution in 40 (53%) and type Ib endoleak in 35 (47%) cases, respectively. Thirteen (17%) patients received bilateral IBDs. Internal iliac artery (IIA) catheterisation was done through a transaxillary access (n = 82, 93%) or up and over (n = 6, 7%) technique. The primary endpoint was technical success. Secondary endpoints were 30 day major adverse event, early and long term freedom from re-intervention and target vessel instability. RESULTS All procedures were technically successful (100%). During hospitalisation, there were four (5%) major adverse events and three (4%) early re-interventions, but no death, stroke, or damage to previous endografts. The median follow up was 47 (interquartile range 42) months, and the five year survival rate was 78 ± 6% with no aortic related death. Cox's regression analysis showed pre-operative renal function impairment (hazard ratio [HR] 3.4; 95% confidence interval [CI] 1.1 - 10.1; p = .033), and primary TAAA repair (HR 6.1; 95% CI 1.6-22.3; p = .006) as independent factors for long term mortality. Freedom from re-interventions was 85 ± 4% at five years with 11 (12%) cases (five endoleaks, four IBD thromboses, two stenoses). IIA instability was reported in three (3%) limbs and freedom from IIA instability was 95 ± 3% after 60 months. CONCLUSION Secondary IBD after EVAR is a safe and effective procedure with high technical success and low complication rates. The technique of choice to revascularise the IIA seems not to affect early and follow up results. Long term durability of IBD repair is acceptable with low rates of IIA re-intervention.

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.
