Lower-profile stent graft reduces the risk of embolism during thoracic endovascular aortic repair in shaggy aorta.

ABSTRACT:

Objectives

This study aimed to reveal the association between lower-profile stent graft (LPSG) and embolism during thoracic endovascular aortic repair for non-dissecting distal arch and descending thoracic aortic aneurysm.

Methods

This study reviewed data of 35 patients who underwent thoracic endovascular aortic repair with LPSG (27 males; age: 77 ± 9.2 years) and 312 who underwent thoracic endovascular aortic repair with conventional-sized stent graft (CSSG) (247 males; age: 77 ± 7.4 years) from 2009 to 2021.

Results

The rate of total embolic events was significantly lower in the LPSG group (0/35 [0%]) than the CSSG group (34/312 [11.2%]) (P = 0.035). Shaggy aorta (odds ratio: 5.220; P < 0.001) were identified as positive embolic event predictors. The rate of total e
