Abstract:

BACKGROUND: The vascular anastomosis technique is directly related to the success or failure of the renal transplantation.
OBJECTIVE: To improve the techniques of variable vascular anastomosis in renal transplantation.
METHODS: 878 cases received renal transplantation in the Department of Organ Transplantation, Guangdong No.2 Provincial People’s Hospital from September 1999 to December 2010 were selected, and the donor renal vascular variation including renal artery and renal vein were treated with trim, merge, extend and other reconstruction processes for renal transplantation, and the accessory renal arteries were anastomosed to inferior epigastric arteries by a modified stereotaxic method.
RESULTS AND CONCLUSION: Among the 878 renal transplantation cases, 55 donor kidneys had renal artery variation and 22 donor kidneys had renal vein variation. All the variable vessels were anastomosed to the internal iliac or external iliac vessels successfully after vascular reconstruction. Twenty-three cases of accessory renal arteries with the diameter of more than 1 mm were anastomosed to inferior epigastric arteries successfully. Color Doppler ultrasound image showed that blood stream was smooth in all anastomosed vessels. Transplant renal vascular variation and accessory renal arteries can be transplanted safely and effectively by correct vascular rebuilding or vascular anastomosis.
