| Popis: | A new type of sutureless aortic-vein-graft vascular anastomostic device, One-Shot Vascular Anastomostic Device (Horologe Factory of Jinan City, Shandong Province, China) has been recently designed to create a one-shot anastomosis between the aorta and vein grafts for coronary artery bypass grafting surgery.Twelve pigs were scheduled for the test of the feasibility of the One-Shot Vascular Anastomostic Device for artery to vein graft anastomosis. In each animal one proximal anastomosis was performed by means of the One-Shot Vascular Anastomostic Device and the distal end was sutured in a conventional manner to serve as the animal own control. The anastomosis incorporating the abdominal main artery to the segment of a free external carotid vein to the external iliac artery is for the simulation of the aorta-vein anastomosis.The mean duration of the completion of the proximal anastomosis was 1.2 +/- 1.2 minutes (range, 0.3-5.0 minutes). There was a significant difference between the control groups (p0.01). All vein grafts were still functioning at the end of the procedure. Pathologic studies and angiography demonstrated that the results were satisfactory.This device enables rapid and safe completion of vascular anastomostic procedure. The vein graft was functioning well and incorporated into the vessel intima smoothly. |
