| Background: In recent decades, endovascular aortic repair (EVAR) has become an acceptable alternative to open surgery for the treatment of thoracic and abdominal aortic aneurysms with lower perioperative mortality as well as a significant reduction in perioperative morbidity. Aim: This study aimed to describe the complications of Endovascular Abdominal Aortic Aneurysm Repair after one year of follow-up. Patients and Methods: A total number of 20 patients presented with infrarenal abdominal aortic aneurysms exceeding 5.5 cm, endovascular abdominal aortic aneurysm repair was done, and patients were followed up for one year postoperative. The imaging modalities for ongoing endograft surveillance were contrast-enhanced computed tomographic (CT) arteriography and duplex ultrasonography (DU). The principal concerns were endoleak, aneurysm sac enlargement, migration of the stents at the aortic and iliac landing zones, and separation of the device components. Results: One patient (5%) died due to cardiac cause (Myocardial infarction), 19 patients (95%) showed aneurysmal sac shrinkage by 1.5+/- cm, 2 patients (10%) showed continued type 2 endoleak without increase in sac pressure or size and conservative follow up was decided. 1 patient (5%) showed stent migration < 5mm without affection of aneurysm exclusion or endoleak. There was a statistically significant reduction in the aneurysmal sac diameter after endovascular repair (7.65 ± 1.5 vs 6.2 ± 1.2) (p < 0.001). AAA with iliac extension was statistically significantly associated with endoleak (6 patients) compared to AAA with infrarenal extension (2 patients) (p=0.025). Patients with infrarenal abdominal aorta of diameter more than 7 cm were statistically significantly associated with endoleak (5 patients) compared to those with infrarenal abdominal aorta of diameter less than 7 cm (2 patients) (p=0.041). Conclusion: This study included 20 patients who presented with infrarenal abdominal aortic aneurysms exceeding 5.5 cm, endovascular abdominal aortic aneurysm repair was done, and proved the efficacy of EVAR and the results showed improvement in the perioperative mortality and morbidity period as compared to similar studies. | ||||
