Endovascular aneurysm repair in short and angulated aortic aneurysmal neck: A retrospective case series of single centre experience

Introduction: The purpose of this study was to analyse the outcomes of endovascular aneurysm repair (EVAR) in patients with aortic aneurysms with short and angulated aortic neck. Methods: This was a retrospective case series of single centre experience. Patients diagnosed with infrarenal abdominal aneurysm with or without iliac aneurysm who underwent endovascular treatment between May 2012 and August 2020 were included in the study. Results: Standardised information of 95 patients who met the inclusion criteria was documented (71 males, 24 females; average age: 73.8 ± 17.6 years). There were 45 patients in group H (short and/or angulated aortic neck anatomy) and 54 patients in group F (control group). The clinical presentations, intervention-related characteristics, and early as well as mid-term results were not statistically different between the two groups. In group H, cases of short aortic neck had higher risk of early type IA endoleak (4 patients, 57.1%). Conclusion: Endovascular aneurysm repair in the treatment of infrarenal abdominal aortic aneurysm is considered safe and effective in cases of both groups. Treatment outcomes and complications were not statistically different between the groups. Nevertheless, cases of aortic short neck had a greater risk of early type IA endoleak and reintervention.
