Zusammenfassung: | Background
Incisional hernia (IH) is a common, late complication of open repair of an abdominal aortic aneurysm (AAA), with a variable high incidence. A cohort study was conducted to investigate the role of a lightweight titanized mesh placed in the pre-peritoneal space after AAA repair. The primary endpoint was to determine the incidence of IH at eight weeks and 12 months.
Methods
Consecutive patients who underwent open repair of AAA with the prophylactic implantation of a mesh after abdominal wall closure were recruited. The development of IH was evaluated using clinical examination, ultrasonography scan (USS), and computed tomography (CT) scan during the follow-up period.
Results
Thirty-nine of 45 patients (34 male, 5 female, mean age 69.6 +/- 6.5 years) undergoing open repair of AAA over a five-year period via a preferred roof-top incision were analyzed for this study. One additional (2.5%) patient had the mesh explanted following a re-laparotomy for colonic ischemia and later developed an incisional hernia. There was no incidence of wound or mesh infection overall. One radiologically detected early IH closed spontaneously. There were five (12.8%) radiologically detected late cases of midline or paramedian defects beyond the one-year follow-up though this was not clinically significant; compared to this, there was no incidence of lateral defects in the wound (p |
