Initial Outcomes of Physician-Modified Inner-Branched Endovascular Repair for Distal Aortic Arch Aneurysm.

Background/

Objectives

Few clinical studies have reported on physician-modified inner-branched endovascular repair (PMiBEVAR) for aortic arch aneurysm. Herein, we evaluate the outcomes of proximal landing zone 2 PMiBEVAR.

Methods

This retrospective study analyzed data from six patients who underwent zone 2 PMiBEVAR for aortic arch aneurysms at a single center between October 2021 and June 2024. The outcomes were in-hospital mortality and postoperative complications.

Results

The median follow-up period was 12.5 (7.3-25) months. Males constituted four out of six cases and females constituted two out of six cases. The patients had a median age of 78.5 (76.5-79.0) years, and the aneurysm diameter was 56 (50-61) mm. Technical success was achieved in 5/6 (83.3%) cases. The median modification and operative times were 56 (45-60) min and 92 (79-308), respectively. Postoperatively, delayed type Ia endoleak and vascular access-site pseudoaneurysm occurred in one patient each. However, no patients experienced other complications. The median hospital stay was 10 (7-41) days, and no deaths or reinterventions occurred after 30 days. During the post-discharge follow-up, the aneurysm diameter remained "unchanged" in four patients, including the one with delayed type Ia endoleak, while two patients experienced "shrinkage".

Conclusions

PMiBEVAR for distal aortic arch aneurysm might be effective in improving postoperative outcomes.
