The chimney endovascular aortic repair technique is an established option for the treatment of juxtarenal aortic aneurysms. Failure of this repair represents a major surgical challenge. We report the case of a patient treated previously with chimney endovascular aortic repair (for a juxtarenal aortic aneurysm), who had developed a large type IA endoleak. The patient was treated with a custom-made endograft with three inner branches. All vessels were successfully cannulated and bridged, no evidence of endoleak was seen on the completion angiogram, and the patient had an uneventful recovery.

Objective: Paravisceral aortic lesions present significant challenges for endovascular treatment. This retrospective analysis of consecutively treated patients from April 2017 to June 2021 aimed to analyse the outcome of primary intra-operative embolisation of aortic complicated pseudoaneurysms and gutter channels during parallel graft (PG) repair of paravisceral symptomatic aortic pseudoaneurysms.
Methods: Patients with symptomatic pseudoaneurysms of the paravisceral aorta treated with PGs using chimney or periscope configurations were included.

Objectives: Endovascular aneurysm repair (EVAR) for large infrarenal abdominal aortic aneurysms (AAA) has been associated with worse outcomes compared to EVAR for smaller AAAs. Whether these findings apply to complex AAAs (cAAA) remains uncertain.
Methods: We identified all intact complex EVAR (cEVAR) from 2012-2024 in the Vascular Quality Initiative.

Background: Thoracic aortic endovascular repair (TEVAR) is the most commonly employed method for treating type B aortic dissection (TBAD). One of the primary challenges in TEVAR is the reconstruction of the left subclavian artery (LSA). Various revascularization strategies have been utilized, including branch stent techniques, fenestration techniques, chimney techniques, and hybrid techniques.

: The parallel stent graft endovascular aortic repair (PGEVAR) technique is an off-the-shelf option used for elective complex abdominal aortic aneurysm repair with acceptable outcome results, as reported so far. The PGEVAR technique, using chimney or periscope parallel grafts, can also be used for patients with ruptured complex abdominal aortic aneurysms. However, only few data about the mid- to long-term outcomes are available.

Introduction: Abdominal aortic aneurysms present a significant clinical challenge, particularly when located near the renal arteries. In cases of infra-renal abdominal aortic aneurysms, the main stent graft may occlude the renal arteries, disrupting blood supply. To prevent this, two 'chimney' stent grafts can be implanted to maintain renal artery perfusion.
