Background: Aorto-iliac occlusion is an advanced and late manifestation of the atherosclerotic vascular disease. Patients with this complicated and frequently multi-level disease can present with debilitating symptoms ranging from life-limiting claudication to limb-threatening ischemia. To study the results of Surgical management and complications of Aortic surgery in a patient with chronic, aortoiliac occlusion.

Methods: Our study of 22 cases, 12 patient underwent aortic bi femoral bypass, 08 cases underwent aortobi-iliac bypass and 2 of them aortic endarterectomy. This entire patient had a 64 slice CT angiogram of aorto with bilateral lower limb and offered surgical treatment after explaining the risk and complication of surgery. All patients followed post op with the clinical examination, ABI, duplex once a month.

Results: 19 patients had a patent graft at the end of the study period. The primary patency of 86%. 2 patient had graft thrombectomy, 1 patient had graft thrombectomy with extension bypass, hence the secondary patency was 95%.

Conclusions: The spectrum of aortoiliac occlusive disease ranges from short, simple stenosis to long, complete occlusions, with treatment options that vary accordingly from minimally invasive endovascular procedures to major open surgical intervention.
