The proximal anastomosis is an important procedure during the acute type A aortic dissection (AAAD) surgery. The conventional method is a double patch sandwich technique with Teflon felt. Adventitial eversion and prosthesis eversion technique as a novel approach has been applied to many patients in our center. Herein, This technique would be introduced, and the perioperative and 1-year follow-up results of the two different anastomosis methods were also evaluated.
Between December 2017 and May 2021, 143 AAAD patients who underwent total arch replacement (TAR) and frozen elephant trunk (FET) implantation were included in this retrospective study. Patients were divided into the eversion technique group (adventitial eversion and prosthesis eversion technique for proximal anastomosis,
The medical records were analyzed and compared between the groups. The mean operation time was 466 ± 73 min in the eversion technique group and 513 ± 81 min in the sandwich technique group (
Proximal anastomosis with adventitial eversion and prosthesis eversion technique is a promising surgical option for AAAD patients, with favorable perioperative and 1-year follow-up results.
