Purpose:
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.
Description:
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.
Evaluation:
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 (p < 0.01). All vein grafts were still functioning at the end of the procedure. Pathologic studies and angiography demonstrated that the results were satisfactory.
Conclusions:
This device enables rapid and safe completion of vascular anastomostic procedure. The vein graft was functioning well and incorporated into the vessel intima smoothly.
