Background:
Prophylactic mesh implantation following open surgical repair of abdominal aortic aneurysm is a debatable subject.
Objective:
To assess the efficacy of a self-gripping polyester mesh used in on-lay technique to prevent incisional hernia after open abdominal aortic aneurysm repair.
Methods:
We retrospectively reviewed the records of 495 patients who underwent aortic surgery between May 2017 and May 2021. Patients included in the study underwent open surgical repair for infrarenal abdominal aortic aneurysm (AAA) with closure of the abdominal wall with either small bite suture technique or prophylactic mesh reinforcement. Primary endpoint of the study was the occurrence of incisional hernia during a two-year follow-up period. Secondary endpoints were mesh-related complications.
Results:
Mesh implantation with the on-lay technique was successful in all cases. No patient in the mesh group developed an incisional hernia during the 24-month follow-up period. Two patients in the non-mesh group developed a symptomatic incisional hernia during the follow-up period at 6 months. Three cases of post-operative access site complications were observed in the mesh group.
Conclusions:
Application of a self-gripping polyester mesh using the on-lay technique demonstrates acceptable early-durability after open surgical repair of abdominal aortic aneurysms. However, it appears to be associated with a number of post-operative access site complications.
