One out of 8 patients needs a reintervention after EVAR during the first 5 years. Two thirds of secondary interventions aim at treating endoleaks. The prevalence of complications doubles in the presence of endoleaks. Fourth generation stent grafts do not lead to a decrease in Type 2-associated reinterventions, but to better prevention of Type 1 and 3 endoleaks. Pretreatment of potential type 2 feeding arteries with embolising agents and treatment of the occurrence of type 2 endoleaks.

Background: Current guidelines recommend preserving at least one of the bilateral pelvic flows in patients with aortoiliac aneurysms. The sandwich parallel graft, using commercially available devices, provides a viable option for patients who fall outside the instructions for use of iliac branch devices. However, gutter endoleak remains a significant challenge.

Objective: Emergent complex abdominal aortic diseases are challenging to treat. During in situ laser fenestration (ISLF), aortic branches are covered and flow is restored with in situ fenestration of the stent graft, with promising midterm results. This study aimed to expand on the limited body of knowledge of midterm outcomes of ISLF in renovisceral aortic pathology in a multicentre setting.

Background: The optimal treatment of complicated type B aortic dissection (cTBAD) involving arch anomalies remain unclear.
Methods: We consecutively enrolled patients with cTBAD involving arch anomalies who underwent endovascular repair using a single-branched stent graft (SBSG) at our medical center between January 2020 and January 2023. The demographics, clinical manifestation, operation detail, and follow-up outcomes of these patients were retrospectively collected and analyzed.

The purpose of this study is to evaluate the feasibility and clinical outcomes of vasa vasorum embolization for preventing continuous aneurysmal expansion after endovascular aneurysm repair (EVAR). We retrospectively reviewed the medical records of patients who underwent vasa vasorum embolization between August 2018 and May 2022. Vasa vasorum embolization was attempted in cases of continuous aneurysmal expansion after EVAR, where the vasa vasorum was identified through catheter angiography.
