Objective: To evaluate the feasibility and short-term clinical outcomes of the Kabedon technique-based endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA) with severe infrarenal neck angulation (angle > 60°). Methods: This retrospective cohort study was based on a single-center database. Between January 2019 and May 2023, 120 patients with AAA of hostile neck angulation underwent endovascular procedures using the Kabedon technique for abdominal aortic remodeling. A standardized protocol was followed to calculate the serial changes in the aneurysmal neck angle. The primary endpoints were proximal type Ia endoleak and stent-graft migration. The secondary endpoints were all-cause and aneurysm-related mortality, proximal neck dilatation, and re-intervention. Results: The mean age was 71.40 ± 10.69 years, and 95 (79.17%) were male. The mean AAA sac diameter and proximal neck angle were 63.71 ± 17.32 mm and 83.67 ± 18.45°, respectively. All patients underwent the Kabedon-based EVAR, with a technical success rate of 94.17% (113/120). During the operation, 7 cases of endoleak and 2 cases of endograft migration were observed, which were resolved by corresponding measures such as coil embolization and proximal cuff stent salvage. No complications were observed within 30 days. In addition, neck calcification, funnel-
