Abstract:
This paper reports the umbilical cord vein (UCV) used as the aotic grafts for dogs and the result o a long term follow-up . The UCVs are treated with 10% formalin. All grafts with follow-up 2-3. 5 years are patent. The lumen at the anastomotic site is slightly narrower and that of the grail is braoder. By the light and electron microscopy the inner wall covered with endothelium is observed . The endothelial cells proliferate actively and range regulary . There are more collagen and a few fibrocytes and myofibroblasts myointimal cell in the intima, but quite few smooth muscle cells in the medium . In conclusion , the umbilical cord veins are convenient for the moderate arterial grafts .
