Background Endovascular aneurysm repair (EVAR) is becoming the mainstay treatment of abdominal aortic aneurisms (AAA). The postoperative follow-up regime includes a lifelong series of CT angiograms (CTAs) at different intervals in addition to EVAR, which will confer significant cumulative radiation exposure over time. Purpose To examine the impact of age and follow-up regime over time on cumulative radiation exposure and attributable cancer risk after EVAR. Material and Methods We calculated a mean effective dose (ED) for the EVAR procedure, CTA, and plain abdominal X-rays (PAX). Cumulative ED was calculated for standard, complex, and simplified surveillance over 5, 10, and 15 years for different age groups. Results For EVAR, the mean ED was 34 mSv (range, 12–75 mSv) per procedure. For PAX, the ED was 1.1 mSv (range, 0.3–4.4 mSv), and for CTA it was 8.0 mSv (range, 2–20 mSv). For a 55-year-old man, an attributable cancer risk (ACR) in standard surveillance at 5 and 15 years of follow-up was 0.35% and 0.65%, respectively. The corresponding values were 0.22% and 0.37% for a 75-year-old man. When using a simplified follow-up, the ACRs for a 55-year-old at 5 and 15 years were 0.30% and 0.37%, respectively. These values were 0.18% and 0.21% for a 75-year-old man. A complex follow-up with half-yearly CTA over similar age and time span doubled the ACR. Conclusion Treating younger patients with EVAR poses a low ACR of 0.65% (15-year standard surveillance) compared to a lifetime cancer risk of 44%. A simplified surveillance should be used if treating younger patients, which will halve the ACR over 15 years.

Purpose We performed antegrade thoracic endovascular aneurysm repair via the ascending aorta in selected high-risk patients scheduled for open surgery, in whom an iliofemoral or abdominal aortic approach was not feasible. We present our initial experience with this approach. Methods Of 16 consecutive patients who underwent antegrade endovascular aneurysm repair via the ascending aorta at our institution, 3 had an emergency intervention for rupture and 3 had an urgent intervention for impending rupture or complicated aortic dissection. The procedure was scheduled in 10 patients. The median patient age was 77 years. In 13 patients, one or more concomitant procedures were performed. In 6 patients, vascular access for endovascular aneurysm repair was obtained via a branch of the replacement graft. In 10 patients, direct cannulation of the ascending aorta was carried out using 2 pursestring sutures. Results The initial success rate was 100%. Early mortality occurred in 2 (12.5%) patients because of multiple organ failure in one and heart failure in the other. No patient required a second intervention during follow-up. The mean duration of follow-up was 19 months. Conclusion The antegrade approach is a useful alternative in patients with no access suitable for endovascular aneurysm repair and who are not appropriate candidates for open conventional thoracic aortic surgery. This approach is applicable to selected patients.

Objective Descending thoracic endovascular aneurysm repair (D-TEVAR) is often performed by vascular surgeons. At many institutions, cardiothoracic surgery support is required for an elective TEVAR to take place. Oftentimes, this means a dedicated cardiopulmonary bypass team must be available. This study aims to investigate that TEVAR is a safe procedure that does not require such a resource-intensive “back-up plan.” Methods This is a retrospective analysis of data collected from March 2014 to January 2018 of 18 patients who underwent TEVAR at a tertiary care facility with a level I trauma center. There were 11 males and 7 females with an average age of 68.8 years old (range 19–97; SD ± 19.52). The average body mass index (BMI) was 24.7 kg/m2 (range 16.8–35; SD ±4.67). Nine were never smokers, four were former smokers, and five were currently smoking at the time of the procedure. The most common presenting symptom prior to intervention was chest pain ( n = 10), followed by cough/dyspnea ( n = 5), back pain ( n = 3), and trauma ( n = 2). Results The average maximum diameter of the thoracic aortic aneurysms (TAA) treated with TEVAR was 5.49 cm ( n = 7; range 4.3–6.7; SD ± 0.855). Six patients had Stanford Type B aortic dissections. Two patients with TAAs had concomitant, rapidly expanding aortic ulcers. Two patients had traumatic pseudoaneurysms, one of which ruptured prior to TEVAR. One patient had an expanding 1.9 × 1.8 cm saccular pseudoaneurysm of the aortic arch. The mean follow-up time was 69.2 weeks ( n = 17; range 3–166; SD ± 62.67), and one patient did not follow up following their initial TEVAR procedure. Of the 18 patients who received TEVAR, there were no major complications. Two patients experienced a type II endoleak. No patients required conversion to an open procedure, nor did any patients necessitate intervention by cardiothoracic surgery or cardiopulmonary bypass support. Conclusion These data suggest that cardiothoracic surgery support is not required for descending thoracic endovascular aneurysm repair (D-TEVAR). Further research is warranted on the risk factors associated with open conversion during these procedures.

We present a case of a 72-year-old male with an abdominal aortic aneurysm status post-endovascular aneurysm repair (EVAR). Follow-up imaging demonstrated an enlarging type II endoleak and attempts at transarterial coil embolization of the inferior mesenteric artery were unsuccessful. The patient underwent image-guided percutaneous translumbar type II endoleak repair using XperGuide (Philips, Andover, MA USA).

Objectives We aim to describe real-world outcomes from multicenter data about the efficacy of adjunct Heli-FX EndoAnchor usage in preventing or repairing failures during infrarenal endovascular aneurysm repair (EVAR), so-called EndoSutured-aneurysm-repair (ESAR). Methods The current study has been assigned an identifier (NCT04100499) at the US National Library of Medicine ( https://ClinicalTrials.gov ). It is an observational retrospective study of prospectively collected data from seven vascular surgery departments between June 2010 and December 2019. Patients included in the ANCHOR registry were excluded from this analysis. The decision for the use of EndoAnchors was made by the treating surgeon or multidisciplinary aortic committee according to each center’s practice. Follow-up imaging was scheduled according to each center’s protocol, which necessarily included either abdominal ultrasound or radiography or computed tomographic scan imaging. The main outcomes analyzed were technical success, freedom from type Ia endoleaks (IaEL), all-cause and aneurysm-related mortality, and sac variation and trends evaluated for those with at least six months imaging follow-up. Results Two hundred and seventy-five patients underwent ESAR in participating centers during the study period. After exclusions, 221 patients (184 males, 37 females, mean age 75 ± 8.3 years) were finally included for analysis. Median follow-up for the cohort was 27 (interquartile range 12–48) months. A median 6 (interquartile range 3) EndoAnchors were deployed at ESAR, 175 (79%) procedures were primary and 46 (21%) revision cases, 40 associated with type IaEL. Technical success at operation (initial), 30-day, and overall success were 89, 95.5, and 96.8%, respectively; the 30-day success was higher due to those with subsequent spontaneous proximal endoleak seal. At two years, freedom from type IaEL was 94% for the whole series; 96% and 86% for the primary and revision groups, respectively; whereas freedom from all-cause mortality, aneurysm-related mortality, and reintervention was 89%, 98%, and 87%, respectively. Sac evolution pre-ESAR was 66 ± 15.1 vs. post ESAR 61 ± 17.5 (p < 0.001) and for 180 patients with at least six-month follow-up, 92.2% of them being in a stable (51%) or regression (41%) situation. Conclusions This real-world registry demonstrates that adjunct EndoAnchor usage at EVAR achieves high rates of freedom from type IaEL at mid-term including in a high number of patients with hostile neck anatomy, with positive trends in sac-size evolution. Further data with longer follow-up may help to establish EndoAnchor usage as a routine adjunct to EVAR, especially in hostile necks.

Purpose: To review a single-center experience with fenestrated and branched endovascular aneurysm repair (f/bEVAR) in patients with challenging iliac anatomies. Materials and Methods: A retrospective review of the department’s database identified 398 consecutive patients who underwent complex endovascular repair f/bEVAR between January 2010 and June 2018; of these, 67 had challenging accesses. The strategies implemented to overcome access issues were reviewed, using a dedicated scoring system to evaluate the access (integrating diameter, tortuosity, calcification, and previous open or endovascular repair). Results: In this subgroup of patients, the most common graft design was a 4-vessel fenestrated endograft (27, 40.3%). Hostile access was due to small diameter (<7 mm) in 25 patients (37.3%) and/or concentric calcifications in 19 patients (26.9%). Mean iliac diameter was 5.5±2.6 mm on the right side and 6.0±2.5 mm on the left side. Previous open or endovascular aortoiliac repair had been performed in 15 patients (22.4%), and 20 patients (29.9%) had a stent previously implanted in at least 1 iliac artery, resulting in the inability to perform standard fenestrated repair with access from both sides. Five patients (7.5%) had a single patent iliac access. Eight distinctive strategies were identified to overcome these access issues, including the use of preloaded renal catheters in the endograft delivery system, angioplasty, graft modification (branches instead of fenestrations or 4 preloaded fenestrations), a conduit via a retroperitoneal approach, iliac artery recanalization, and/or the multiple puncture technique. Technical success was achieved in 62 cases (92.5%). Four patients had access complications and 1 died in the early postoperative period of multiorgan failure. Median follow-up was 24.6 months (IQR 7.2, 41.3). Clinical success at the end of follow-up was achieved in 57 patients (85.1%). During follow-up, 14 patients died, including 4 from an aorta-related cause. Conclusion: Dedicated strategies can be implemented to overcome hostile iliac access in patients with complex aneurysms when f/bEVAR is required. Typically, these maneuvers are associated with favorable outcomes.

Purpose: Fenestrated endovascular aneurysm repair (FEVAR) is a well-established endovascular treatment option for pararenal abdominal aortic aneurysms in which balloon-expandable covered stents (BECS) are used to bridge the fenestration to the target vessels. This study presents midterm clinical outcomes and patency rates of the Advanta V12 BECS used as a bridging stent. Methods: All patients treated with FEVAR with at least 1 Advanta V12 BECS were included from 2 large-volume vascular centers between January 2012 and December 2015. Primary endpoints were freedom from all-cause reintervention, and freedom from BECS-associated complications and reintervention. BECS-associated complications included significant stenosis, occlusion, type 3 endoleak, or stent fracture. Secondary endpoints included all-cause mortality in-hospital and during follow-up. Results: This retrospective study included 194 FEVAR patients with a mean age of 72.2±8.0 years. A total of 457 visceral arteries were stented with an Advanta V12 BECS. Median (interquartile range) follow-up time was 24.6 (1.6, 49.9) months. The FEVAR procedure was technically successful in 93% of the patients. Five patients (3%) died in-hospital. Patient survival was 77% (95% CI 69% to 84%) at 3 years. Freedom from all-cause reintervention was 70% (95% CI 61% to 78%) at 3 years, and 33% of all-cause reinterventions were BECS associated. Complications were seen in 24 of 457 Advanta V12 BECSs: type 3 endoleak in 8 BECSs, significant stenosis in 4 BECSs, occlusion in 6 BECSs, and stent fractures in 3 BECSs. A combination of complications occurred in 3 BECSs: type 3 endoleak and stenosis, stent fracture and stenosis, and stent fracture and occlusion. The freedom from BECS-associated complications for Advanta V12 BECSs was 98% (95% CI 96% to 99%) at 1 year and 92% (95% CI 88% to 95%) at 3 years. The freedom from BECS-associated reinterventions was 98% (95% CI 95% to 100%) at 1 year and 94% (95% CI 91% to 97%) at 3 years. Conclusion: The Advanta V12 BECS used as bridging stent in FEVAR showed low complication and reintervention rates at 3 years. A substantial number of FEVAR patients required a reintervention, but most were not BECS related.
