Brief Summary:

AIDA Study is a prospective, multicentre, randomized, controlled clinical investigation with patients undergoing median laparotomy for Abdominal Aortic Aneurysm (AAA) repair.

The primary objective of the clinical investigation is to test the hypothesis that insertion of an Optilene® Mesh Elastic mesh - a monofilament, light-weight, large pore sized, polypropylene mesh manufactured by Aesculap AG - is superior to suturing alone and will reduce the hernia formation rate within the first 2 years.

A reduction from 30% to 10% of the patient population is assumed.

Abdominal Aortic Aneurysm Procedure: Optilene® Mesh Elastic Phase 4

Arm Intervention/treatment
No Intervention: Group A
Monofilament absorbable MonoPlus® suture material will be used for closing of the midline incision.
Group B
Abdominal wall closure with monofilament absorbable MonoPlus® suture material and onlay placement of Optilene® Mesh Elastic fixed by sutures.
Procedure: Optilene® Mesh Elastic
A number of patients will receive a Optilene® Mesh Elastic mesh, which may not be clinically indicated.

No Intervention: Group C
Monofilament, absorbable MonoMax suture material will be used for the closure of the abdominal cavity.

Primary Outcome Measures :
  1. Herniation rate [ Time Frame: 24 months ]
    As an indicator of efficacy, the reduction of herniation rate will be verified by clinical examination and confirmed by Ultrasound.
