Inclusion criteria

Inclusion criteria: - Open surgical repair of an abdominal aortic aneurysm • Surgery at Magdeburg University Hospital • Period: 2006 to 2022 • Use of a modified suturing technique from the Vascular Surgery Department • Availability of a clinical follow-up period of at least 12 months • Emergency treatment of ruptured abdominal aortic aneurysms • Conversion surgeries after EVAR • Revision surgeries due to long-term complications (e.g., endoleak, infection, recurrence) • Individual cases with aneurysms of the iliac artery or superior mesenteric artery (evaluated separately)

Exclusion criteria

Exclusion criteria: • Endovascular or laparoscopic procedures • Use of a different suture technique • Mesh insertion during the index surgery • Death before 12 months of follow-up • Follow-up < 12 months (even with complete documentation) • Incomplete data sets (e.g., no surgical documentation or no follow-up) • Re-laparotomy with a new abdominal wall closure before the occurrence of an incisional hernia

Design outcomes

Primary

Measure	Time frame
Occurrence of an incisional hernia after open BAA surgery using the modified suture technique, especially frequency in relation to the total number of operations	—

Secondary

Measure	Time frame
• Association between incisional hernia incidence and statistically determined risk factors with significant influence (e.g., BMI, smoking status, duration of surgery, pre-existing conditions, etc.) • Comparison of our own surgical results on incidence determined using descriptive statistics with published data (PRIMA study, Dewulf et al. 2022) • Proportion of patients undergoing surgical revision due to an incisional hernia (as a measure of clinical relevance)	—
