BACKGROUND: Incisional hernias after open abdominal aortic aneurysm (AAA) repair can cause significant morbidity and affect quality of life. The aim of this study was to investigate the incidence of incisional hernias after elective open aortic or iliac artery aneurysm (IAA) repair, and to identify risk factors for incisional hernia development.
METHODS: This was a retrospective cohort study including patients who underwent elective open repair for AAA/IAA at the Department of Vascular Surgery, Oslo University Hospital, from 2010 to 2022. Data on patient characteristics and surgery related factors were collected from the medical records. Postoperative incisional hernias were registered if detected either on clinical examination or on postoperative computed tomography (CT) scans.
RESULTS: In total, 298 patients were included, and 160/298 patients (54%) had postoperative CT scans available. Median follow-up time was 8.5 (interquartile range 6.5) years. A total of 85/298 (29%) incisional hernias were detected. Clinically detected incisional hernias constituted 56/298 (19%); of which, 31/56 (55%) were reported to be symptomatic and 8/56 (14%) had undergone hernia repair. Body mass index (BMI) was the only independent variable that was significantly associated with the development of incisional hernia (odds ratio 1.10; 95% confidence interval (1.03, 1.18); P = 0.007).
CONCLUSION: Incisional hernias after open AAA/IAA repair were common, but few were symptomatic, and very few underwent hernia repair. BMI was a significant risk factor for the development of incisional hernia.
