Abstract

Objective: To review the early results of endovascular repair for unruptured infrarenal abdominal aortic aneurysm (AAA) in our centre in 3 years experience of elective endovascular aortic repair. Subject and method: A descriptive cross-sectional study was conducted 35 patients with unruptured infrarenal AAA treated by endovascular aneurysm repair (EVAR) enrolled from January 2018 to March 2021 in Cardiovascular Institute of 108 Military Central Hospital, in which 20 retrospective and 15 prospective, followed up in 3 months. Result: There was 29 men and 6 women in the patient population, with an average age of 70.1 years. Fusiform aneurysm was dominant with 88.6%, secondly saccular aneurysm 8.6% and one dissection. The mean maximum AAA diameter was 62.94 ± 14.11mm. The proximal aortic neck had a mean diameter of 20.35 ± 3.38mm, maximum 28.9mm, and neck length of 29.79 ± 11.18mm, a mean infrarenal neck angulation of 43.3 ± 22.83 degrees, maximum 103.8 degrees. The mean right common iliac diameter was 18.1mm, and the left common iliac was 17.27mm. Common iliac aneurysm was identified in 21 cases. The mean procedural duration was 148.74 mins. Technical success was achived in 33 patients (94.3%). Major adverse events within 30 days were recorded in 4 patients (11.4%). Endoleaks at the complete angiogram were present in 7 patients included 2 type I endoleaks and 5 type IV endoleaks. After three months follow-up, one reintervention was required due to endoleak type I combined migration, occlusion of one of the iliac limbs was reported in 4 patients required a bypass procedure. Conclusion: The endovascular aneurysm repair for unruptured infrarenal abdominal aneurysm had high technical success rate in tandem with low-rate early complications and no mortality. However, longer-term follow-up is necessary to assess durability of these results.
