Key result
Interrupted pledgeted proximal anastomosis during open abdominal aortic aneurysm repair significantly reduced the need for additional suture reinforcement compared to continuous anastomosis (43.3% vs 72.9%, P=0.002).
Why the study?
The authors sought to describe the interrupted pledgeted proximal aortic anastomosis technique and compare its outcomes to the traditional continuous running suture technique during open abdominal aortic aneurysm repair.

Does interrupted pledgeted proximal anastomosis reduce the need for suture reinforcement compared to continuous anastomosis in patients undergoing open abdominal aortic aneurysm repair?
The proximal anastomosis is a crucial step during open repair of an abdominal aortic aneurysm. A technically sound anastomosis decreases intraoperative blood loss, as well as the operative time needed for suture line repair. Traditionally, a continuous running suture is used for the construction of this anastomosis. At the author's institution, the technique of an interrupted pledgeted proximal anastomosis is selectively used when the quality of the aortic tissue is suboptimal. This report describes the technique of the interrupted pledgeted proximal aortic anastomosis and compares outcomes to the traditional continuous technique. Among 60 pledgeted and 48 continuous anastomoses, we found equivalent clamp time, operative time, and intraoperative estimated blood loss for the two techniques. However, patients with a continuous anastomosis had higher risks of additional reinforcement during hospitalization (43.3% pledgeted vs 72.9% continuous; P = .002). The interrupted anastomotic technique presented here is a valuable option in open abdominal aortic aneurysm repair when faced with friable aortic tissue.

Cóbar et al. (2025) conducted a cohort in Abdominal aortic aneurysm (n=108). Interrupted pledgeted proximal anastomosis vs. Continuous anastomosis was evaluated on Need for additional reinforcement of the anastomosis (p=0.002). Interrupted pledgeted proximal anastomosis during open abdominal aortic aneurysm repair significantly reduced the need for additional suture reinforcement compared to continuous anastomosis (43.3% vs 72.9%, P=0.002).
