Abstract

Introduction

Current root reinforcement methods for acute type A aortic dissection (ATAAD) risk the tearing of endothelial tissue by sutures. This study proposed a novel technique for aortic root reinforcement and evaluated its effectiveness.

Methods

Patients who diagnosed with ATAAD and had mild to moderate aortic root involvement, combined with aortic arch involvement undergoing Sun's procedure in the First Affiliated Hospital of Xi'an Jiaotong University from January 2020 to December 2021, were retrospectively enrolled. They were divided into two groups according to their surgical procedures of aortic root: continuous aortic root suture group (CARS group) and aortic root reinforcement combined with vascular grafts eversion and built-in procedure (XJ-procedure) group. The 30-day mortality rates and incidence of operation-related complications were evaluated.

Results

The study cohort comprised 183 patients, including 114 in the XJ-procedure group. The 30-day mortality rates were 7.2% in the CARS group and 6.9% in the XJ-procedure group (P = 1.000). The incidence of residual aortic root dissection in the XJ-procedure group was lower than that in the CARS group before discharge (1.8% vs. 10.1%, P = 0.028), at 3-month (0% vs. 8.7%, P = 0.002) and 6-month (0% vs. 7.2%, P = 0.007) follow-up. In the CARS group, the incidence of anastomotic pseudoaneurysm was 2.9%, 2.9%, and 2.9% compared with none in the XJ-procedure group before discharge, at 3 and 6 months. The XJ-procedure group also showed less chest tube drainage in the first 24-h after the surgery, with lower incidence of hemodialysis and sepsis during hospitalization. No differences were observed in the incidence of bleeding necessitating reoperation and severe aortic regurgitation between the two groups.

Conclusions

The XJ-procedure did not increase 30-day mortality and effectively reduced the incidence of residual aortic root dissection during the 6-month follow-up. Subsequent studies with larger samples and prolonged follow-up are needed to evaluate it.

NCT05751200.

The video showed the partial process of the XJ-procedure in managing the aortic root in the ATAAD surgery. The vascular graft was folded outward about 15 mm, and the eversion was intermittently sutured to the full layers aortic wall using 2-0 pad polyester sutures. Then, the eversion of the graft and aortic wall were continuously sutured in one more turn using 3-0 polypropylene sutures.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
