摘要
我们在临床应用不等边距对端吻合法行口径相差较大血管吻合的基础上,设计用口径为0.3mm～0.4mm的微小动脉修复一段口径为1.0mm～1.4mm的动脉缺损的动物实验,术后取得很高的通畅率(96％)。光镜及电镜检查表明吻合口平滑,移植的微小动脉与大动脉愈合良好,具有临床应用的可行性。
Based on our clinical experience for years of "unequal bite" suturing tech- nique to perform end-to-end anastomosis of vessels with great discrepancy in diameter, the animal experimental study was carried out. An artery defect; 1.0～1.4mm in diameter, was reunited with, an autogenous arterial graft of 0.3～0.4mm in diameter. A high paten- cy rate (96% in total) was obtained postoperatively. Histological examination by light mi- croscope and scanning electron microscope showed that the unequal bite suturing technique can produce very smooth anastomotic junction and the minute arterial grafts healed well on a large artery. The unequal bite suturing technique is a very valuable development of the basic end-to-end anastomotic technique. A small autogenous arterial graft may be used to repair defect of an artery with large calibre clinically.
