Sutureless intraluminal graft for repair of high abdominal aortic aneurysm.

The aim of our study was experimental and clinical assessment of bifurcated grafts with ring on its main branch made of the same polyester as the prosthesis. This type of prosthesis facilitates quick anastomosis with the aorta through tying the aortic wall on the ring using a polyester tape. Experimental studies carried out on 18 pigs demonstrated good healing up of such a graft. The prosthesis was used for surgery in 8 patients with abdominal aneurysm which required clamping the aorta above renal arteries. The prosthesis was found to facilitate and accelerate making the proximal anastomosis, diminish the amount of blood loss, and reduces the time of the surgery, especially the time necessary for clamping the aorta above renal arteries which prevents renal ischaemia.
