Evaluating normothermic artery bypass and visceral-anastomosis-first strategy in thoracoabdominal aortic aneurysm repair: propensity-weighted analysis.

ABSTRACT:

Objective

To assess the effectiveness and safety of a normothermic artery bypass and visceral-anastomosis-first (NABV) strategy for thoracoabdominal aortic aneurysm repair.

Methods

From July 2017 to September 2024, a retrospective analysis was conducted on early postoperative complications in two groups of patients undergoing thoracoabdominal aortic aneurysm repair. The analysis compared patients treated with a new strategy with those treated with deep hypothermic circulatory arrest, clarifying the protective effects of the new strategy on visceral organs, particularly the spinal cord.

Results

A total of 182 patients were included in the study; 73 in the NABV group and 109 in the DHCA group. After inverse probability of treatment weighting, the NABV group had lower in
