Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Does mesh reinforcement reduce the incidence of incisional hernias?
* What is the frequency of associated postoperative complications? Researchers will compare the outcomes of patients who underwent mesh-reinforced closures to literature-reported outcomes for non-mesh cases to assess differences in IH incidence and complications.
Participants will:
* Undergo clinical follow-ups and abdominal ultrasounds to detect IH.
* Complete quality-of-life questionnaires (EQ-5D and PROMIS).

Prophylactic mesh reinforcement after open aortic aneurysm repair
Patients who underwent open abdominal aortic aneurysm (AAA) repair with prophylactic retromuscular mesh reinforcement at the Fribourg Cantonal Hospital between 2019 and 2024.
Prophylactic retromuscular mesh reinforcement
Prophylactic retromuscular mesh placement involves reinforcing the abdominal wall during closure after open abdominal aortic aneurysm (AAA) repair to prevent incisional hernias. This technique creates a retro-muscular space by carefully dissecting the rectus abdominis muscles from the posterior rectus sheath. A self-gripping polyester mesh or composite mesh is placed in this space, extending 4 cm beyond the midline on each side, ensuring tension-free coverage. The mesh is secured at key points, and the rectus sheaths are closed with continuous sutures. This approach leverages the anatomical integrity of the abdominal wall to reduce hernia risk without increasing postoperative complications.
