Intermittent horizontal mattress suture in proximal anastomosis for acute type A aortic dissection: a retrospective study.

ABSTRACT:

Objective

To compare intermittent horizontal mattress suture (IHMS) technique and conventional sandwich technique for proximal anastomosis in acute type A aortic dissection (ATAAD) surgery.

Methods

Patients who underwent ATAAD repair in our hospital between December 2020 and February 2023 were selected for inclusion in the study. The number of patients treated with the IHMS technique for aortic root repair were matched with those who received the conventional sandwich technique by the same surgeon. Perioperative and postoperative outcomes were analyzed and compared between the two groups.

Results

This study compared 44 patients in each group. The IHMS group had a shorter operation time than the sandwich group (6.07 h vs. 7.02 h, p = 0.018). The proximal
