A-modified skill of tri-cuff vascular anastomosis for the establishment to orthotopic small bowel transplantation in rats / 重庆医科大学学报

ABSTRACT

Objective:To improve the surgical skill of Tri-cuff vascular anastomosis of the rat small intestinal transplantation. Methods:Artery anastomosis was done by employing the cuff anastomosis between a segment of donor abdominal aorta with superior mesenteric artery and recipient abdominal aorta.Venous anastomosis was done by employing the cuff anastomosis between dornor's vein and recipient's left renal vein.Results:The survival rate in 60 rats with small intestinal transplantation was 93.3%(56/60).Total operation time was about1.5～2h.The average times for the arterial anastomosis and venous anastomosis were (4?1)min and 1 min respectively.Conclusion:The modified skill of Tri-cuff vascular anastomosis for the orthotopic small bowel transplantation in rats speeds the vascular anastomosis and shortens the operation time,reduces the complications of the operation and improves the operation survival rate.
