Laparoscopy is a minimally invasive alternative for type II endoleak repair after endovascular aneurysm repair. However, control of lumbar and median sacral arteries is considered technically difficult due to the dense inflammatory tissue surrounding the aorta. We describe a technical tip that avoids close dissection of the aneurysm sac. After the transperitoneal approaches we commonly use during laparoscopic aortic surgery, the aneurysm is drawn rightward to access the plane of the anterior longitudinal ligament. This technique allows a direct exposure of the lumbar and median sacral arteries, which are all methodically dissected and ligated along the anterior wall of the spine without close dissection of the aneurysm sac. In our experience, this technical tip was always feasible and simplified laparoscopic type II endoleak repair.

Comparison of treatment outcomes between graft replacement and aneurysmorrhaphy with graft preservation for type 2 endoleaks after endovascular abdominal aortic aneurysm repair.

Objective: This study aimed to compare treatment outcomes between graft replacement and aneurysmorrhaphy with ligation of the aortic side branches for type 2 endoleaks after endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms.
Methods: We retrospectively analyzed multicenter data of patients who underwent open surgical conversion, including graft replacement or aneurysmorrhaphy with ligation of the aortic side branches (graft preservation) for the treatment of type 2 endoleaks between 2007 and 2022. The endpoints were postoperative complications, 30-day mortality, overall survival, and reintervention or sac expansion after open surgical conversion.
Fenestrated Anaconda Endograft for the Treatment of Complex Aortic Aneurysms: Systematic Review and Meta-Analysis.

Purpose: To perform a systematic review and meta-analysis of the outcomes of Anaconda fenestrated endograft for the treatment of complex abdominal aortic aneurysms (cAAA).
Material And Methods: A systematic search of all the literature reported until May 2024 was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The pooled 30-day mortality rate, technical success rate, reintervention rate as well as bridging stent occlusion rate, and corresponding 95% confidence intervals (CIs) were estimated using fixed or random effect methods.

A type 2 endoleak (EL2) remains the most prevalent complication of endovascular aortic repair (EVAR) for an abdominal aortic aneurysm (AAA). We conducted a retrospective, single-center analysis, including patients who underwent embolization for an isolated EL2 after EVAR. The study population was stratified into two groups: Group A, consisting of patients whose EL2 resolved after the first embolization procedure, and Group B, consisting of those with refractory EL2 (rEL2).

: This study aimed to evaluate whether gender-related anatomical differences in proximal aortic neck morphology affect the feasibility and outcomes of endovascular aortic aneurysm repair (EVAR) in women with abdominal aortic aneurysms (AAA). : This study performed a retrospective analysis of patients electively treated by EVAR for infrarenal AAA between January 2019 and December 2023. Demographics, anatomical characteristics, and stent graft details were analyzed.

Purpose: To report a case series on using a novel semi-branch feature in custom-made stent-grafts in the endovascular treatment of complex aortic aneurysms and summarize the contemporary usage of this technology.
Case Series: Four patients underwent endovascular aortic aneurysm repair (EVAR) with a custom-made semi-branch stent-graft (Semi-Branch Endovascular Aortic Aneurysm Repair [SBEVAR]). Two male patients, 75- and 76-year-old, were treated due to failed EVAR with late-type Ia endoleak, and the other two, 80- and 55-year-old male patients, due to a juxta-renal aortic abdominal aneurysm (JRAAA).
