Endovascular Management and Outcomes of Aortoiliac Occlusive Disease

Introduction: Aorto-iliac Occlusive Disease (AIOD) involves the infra-renal aorta and the iliac arteries. Recent studies advocate endovascular management in TASC C and D lesions also. It involves balloon angioplasty with or without stent deployment.5 The aim of this retrospective study is to evaluate the results of endovascular balloon angioplasty and primary stenting in patients of AIOD. Methods: Twenty-five patients with Aorto-iliac occlusion disease who met the inclusion criteria during 1-year study period were included. Patients with acute thrombosis, abdominal aorta or iliac artery aneurysm and additional common femoral artery occlusion were excluded. The TASC II classification was used to define the characteristics of the lesions. The baseline data, procedural details and follow-up results were analysed. Results: Amongst 25 patients studied, age ranged from 40-75 years. Self-expanding metallic stent was employed in all patients. Technical success following primary stenting was achieved in all patients. Procedural times for TASC-II A, B, C and D lesions were 90+ 30, 110+ 40, 135+35 and 155+ 45 minutes, respectively. During follow-up, the cumulative primary patency rates at 1 month and 6 months were 100%. Cumulative primary patency rates at 1 year were 91.67%. Conclusion: Short- term outcomes of balloon angioplasty and stenting for Aorto-iliac artery occlusions in terms of primary patency rates were excellent.
