摘要
本文报告用10％福尔马林处理的胎儿脐带静脉作为狗腹主动脉移植的远期效果。2例长达2年及3年半的移植物均通畅,吻合口稍窄,管腔略增宽。光电镜检查移植物内壁大部分区域平坦、光滑。内皮细胞覆盖内膜,内膜以胶原纤维为主,少量成纤维细胞,间有肌纤维母细胞。中膜平滑肌细胞较少,几乎胶原化。脐带静脉可供中等动脉移植用。
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 .
