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.

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.

Purpose: The aim of this study was to evaluate the incidence, risk factors, and outcome of endoleaks related to endovascular aneurysm repair (EVAR) procedure at a single center with up to 10 years’ surveillance. Materials and Methods: All patients treated with EVAR for an abdominal aorta or iliac aneurysm in a 10-year period at a single cardiovascular center in Denmark were included. Data were collected from a national database and patient journals. Follow-up computed tomography angiography and plain abdominal X-ray reports were reviewed. Results: A total of 421 patients were included. There were 125 endoleaks observed in 117 (27.8%) patients after a median 95 days (interquartile range: 90-106 days). There were 16 type I, 107 type II, 1 type III, and 1 type V endoleaks. A total of 33 (7.8%) patients had at least 1 reintervention. Patients with type II endoleaks had significantly fewer active smokers and lower plasma creatinine at baseline. They also more often had one, or both, internal iliac arteries embolized as well as an identified endoleak at the procedural completion angiogram. Non-type II endoleaks were associated with internal iliac artery embolization. There was no association between the occurrence of endoleaks and increased mortality. Conclusion: Type II endoleaks are common after EVAR, yet few lead to reintervention. Absence of smoking, low plasma creatinine, embolized iliac arteries, and endoleak on completion angiogram were associated with type II endoleaks, whereas only embolized iliac arteries were associated with non-type II endoleaks. Overall, endoleaks are not associated with increased mortality.

Objectives Marfan syndrome patients are at risk for aortic degeneration. Repair is traditionally performed with open surgery as this is deemed more durable. Endovascular aneurysm repair remains controversial. We report on the outcomes of Marfan syndrome patients with abdominal aortic aneurysms undergoing endovascular aneurysm repair. Methods The Vascular Quality Initiative registry identified 35,889 patients, including 29 with Marfan syndrome, treated with endovascular aneurysm repair from January 2003 to December 2017. Outcomes were analyzed per the Society for Vascular Surgery reporting standards. Results Median age was 70.0 years (IQR, 57.0–75.0), and 22 (75.9%) were male. Median aneurysm diameter was 5.3 cm (IQR, 4.9–6.3 cm), with an aortic neck length and diameter of 2.0 cm (IQR, 1.6–2.8 cm) and 2.5 cm (IQR, 2.2–2.8 cm), respectively. Twenty-one (72.4%) patients were asymptomatic, seven (24.1%) symptomatic, and one (3.4%) presented with rupture. Ten (34.5%) patients had prior aortic surgery. Six (20.7%) were unfit for open surgical repair. Length of stay was 2.0 days (IQR, 1.0–3.0 days). Percutaneous femoral access was performed in 15 (51.7%) patients with no complications. A type IA endoleak was present in one (3.4%), type IB in one (3.4%), and type II endoleak in two (6.9%) patients. There were no postoperative pulmonary, cardiac, or neurological complications. In-hospital mortality occurred in one (3.4%) patient who presented with a rupture and had been deemed unfit for open repair. A conversion to open repair was required. The patient expired on post-operative day 0. Early clinical success was achieved in 26 (89.7%) patients. Follow-up was available for 15 (51.7%) patients at a median time of 766 days (IQR, 653–937). There were no reinterventions or mortalities. Change in sac diameter was −0.6 cm (IQR, −1.1 to −0.2 cm), with no type I or III endoleaks. Discussion Endovascular aneurysm repair for patients with Marfan syndrome is feasible, and can be performed safely. Mid-term outcomes suggest this technique is durable. More robust long-term follow-up is needed.

Objectives Stent grafts for endovascular repair of infrarenal aneurysms are commercially available for aortic necks up to 32 mm in diameter. The aim of this study was to evaluate the feasibility of endovascular repair with large thoracic stent grafts in the infrarenal position to obtain adequate proximal seal in wider necks. Methods All patients who underwent endovascular aneurysm repair using thoracic stent grafts with diameters greater than 36 mm between 2012 and 2016 were included. Follow-up consisted of CT angiography after six weeks and annual duplex thereafter. Results Eleven patients with wide infrarenal aortic necks received endovascular repair with thoracic stent grafts. The median diameter of the aneurysms was 60 mm (range 52–78 mm) and the median aortic neck diameter was 37 mm (range 28–43 mm). Thoracic stent grafts were oversized by a median of 14% (range 2–43%). On completion angiography, one type I and two type II endoleaks were observed but did not require reintervention. One patient experienced graft migration with aneurysm sac expansion and needed conversion to open repair. Median follow-up time was 14 months (range 2–53 months), during which three patients died, including one aneurysm-related death. Conclusions Endovascular repair using thoracic stent grafts for patients with wide aortic necks is feasible. In these patients, the technique may be a reasonable alternative to complex endovascular repair with fenestrated, branched, or chimney grafts. However, more experience and longer follow-up are required to determine its position within the endovascular armamentarium.

Purpose: To provide insight into the evolution of the saddle-shaped proximal sealing rings of the Anaconda stent-graft after endovascular aneurysm repair (EVAR). Methods: Eighteen abdominal aortic aneurysm patients were consecutively enrolled in a single-center, prospective, observational cohort study (LSPEAS; Trialregister.nl identifier NTR4276). The patients were treated electively using an Anaconda stent-graft with a mean 31% oversizing (range 17–47). According to protocol, participants were to be followed for 2 years, during which 5 noncontrast electrocardiogram-gated computed tomography scans would be conducted. Three patients were eliminated within 30 days (1 withdrew, 1 died, and a third was converted before stent-graft deployment), leaving 15 patients (mean age 72.8±3.7 years; 14 men) for this analysis. Evolution in size and shape (symmetry) of both proximal infrarenal sealing rings were assessed from discharge to 24 months using dedicated postprocessing algorithms. Results: At 24 months, the mean diameters of the first and second ring stents had increased significantly (first ring: 2.2±1.0 mm, p<0.001; second ring: 2.7±1.1 mm, p<0.001). At 6 months, the first and second rings had expanded to a mean 96.6%±2.1% and 94.8%±2.7%, respectively, of their nominal diameter, after which the rings expanded slowly; ring diameters stabilized to near nominal size (first ring, 98.3%±1.1%; second ring, 97.2%±1.4%) at 24 months irrespective of initial oversizing. No type I or III endoleaks or aneurysm-, device-, or procedure-related adverse events were noted in follow-up. The difference in the diametric distances between the peaks and valleys of the saddle-shaped rings was marked at discharge but became smaller after 24 months for both rings (first ring: median 2.0 vs 1.2 mm, p=0.191; second ring: median 2.8 vs 0.8 mm; p=0.013). Conclusion: Irrespective of initial oversizing, the Anaconda proximal sealing rings radially expanded to near nominal size within 6 months after EVAR. Initial oval-shaped rings conformed symmetrically and became nearly circular through 24 months. These findings should be taken into account in planning and follow-up.

Purpose: Migration is a major cause of reintervention after endovascular aneurysm repair (EVAR). In patients with common iliac artery (CIA) dilation due to proximal migration of the iliac limb, internal iliac blood flow can be preserved by implanting an iliac branch device (IBD). Case Report: In this report, we discuss the case of a patient in whom the bilateral limbs were completely displaced into the aortic aneurysm due to proximal migration of the iliac limb after EVAR. By taking advantage of the characteristics of this migration, we formed a pull-through wire through the native terminal aorta without passing through the flow divider of the stent graft, and the IBD was deployed safely. Conclusion: The present case indicates that the preservation of at least 1 internal iliac artery is possible in patients with CIA dilation due to proximal migration of the iliac limb. However, the unique features of each case must be considered to determine the appropriate approach.
