Objectives: This study aims to evaluate the three-year patency rates of aortofemoral bypass surgery in the clinical and radiological diagnosis of Trans-Atlantic Inter-Society Consensus (TASC)-C and TASC-D aortoiliac lesions.
Patients and methods: Medical records of a total of 28 patients (21 males, 7 females; mean age: 64.8±8.6 years; range, 58 to 72 years) with TASC-C and TASC-D aortoiliac lesions who underwent aortofemoral bypass surgery between September 2014 and December 2018 were retrospectively analyzed. Demographic and clinical characteristics of the patients were recorded. All operations were performed by a single surgical team by placing a Y graft in the anatomical location and using open median laparotomy technique. The Y graft bypass results with peri- and postoperative data were evaluated.
Results: Dacron Y grafts were used in 18 of TASC-C (25%) and TASC-D (75%) lesions, and polytetrafluoroethylene Y grafts were used in 10 of them. No reoperation or amputation was performed in any patient during follow-up. The mean patency of vascular Y grafts was 92% after three years. There was no significant difference between the graft types and postoperative patient values (p>0.05). Mortality was observed in one patient due to systemic inflammatory response syndrome.
Conclusion: The patency of vascular grafts for aortoiliac occlusive disease is satisfactory in TASC-C and D lesions.
