Background/Aim. Although distal venous patch and cuff techniques are recommended to improve the patency of by-pass in the lower extremities, the advantage of these techniques remains unproven. Autovenous bypass graft remains the method of choice, but when there is no possibility of using the great saphenous vein, the venous cuff method may have an advantage. The aim of this study was to evaluate the results of femorodistal bypass procedures with a venous cuff in critical lower extremity ischemia. Methods. The study described the results of femorodistal bypass procedures after a follow-up period of 6 to 24 months. We followed 28 patients with distal composite anastomosis of femorodistal arterial reconstruction. Indications for surgical treatment were set on the basis of the clinical exam and morphological criteria based on multidetector computed tomographic angiography. Three types of distal graft-arterial anastomoses were applied: Miller’s cuff, Taylor’s patch, and St. Mary’s vein boot anastomosis. Results. After 6 months of surgery, all bypasses were passable; after one year, 2 (7%) patients had graft occlusion and above-knee amputation, and 8 (28%) patients died; after 24 months, 18 (64%) patients had primary bypass patency. Conclusion. Femorodistal bypass procedures using a synthetic graft and venous cuff have good long-term results. The optimal anastomosis type is St. Mary’s boot. A longer follow-up period and comparison with the autovenous bypass are necessary for a more detailed assessment of the final conclusion.
