摘要

Background

Postoperative pulmonary complications (PPCs) are common after surgery in patients with acute type A aortic dissection (ATAAD). This study aimed to evaluate the incidence and risk factors for PPCs in ATAAD patients.

Methods

This single-center retrospective study included 203 patients with ATAAD who underwent urgent aortic surgery between January 2023 and August 2024 Patients were divided into PPCs and non-PPCs groups. The incidence and types of PPCs were recorded, and risk factors were analyzed using multivariable logistic regression. Postoperative outcomes were compared between two groups.

Results

Patients undergoing surgery for ATAAD, 36 (17.7%) developed PPCs. Multivariable logistic regression analysis identified obese as an independent risk factor for PPCs (adjusted OR 3.805, 95% CI 1.408–10.285, P = 0.008).

Conclusions

Obese was an independent risk factor for PPCs in patients undergoing surgery for ATAAD. These findings highlight the importance of preoperative BMI assessment in optimizing perioperative management.
