Abstract

著者들은 흰쥐의 股動脈과 股靜脈을 利用하여 手術顯微鏡下에서 吻合 手術하였을 때 吻合部의 組織學的 變化를 吻合后 1時間, 2日, 1週, 2週, 3週, 및 4週의 時間 經過에 따라 光學顯微鏡 및 透過電子顯微鏡으로 觀察하여 다음과 같은 結果를 얻었다.
1. 吻合에 使用한 흰쥐 (280∼320㎎)의 血管外經은 股動脈이 約 0.4∼1.0㎜였고 股靜脈은 0.8∼1.5㎜ 였다.
2. 血管 吻合은 BV 75-3 10-0 nylon을 使用하며 股動脈은 6∼8個, 股靜脈은 6∼10個의 縫合으로 吻合하였다.
3. 吻合后 開存率은 股動脈이 97.4% 股靜脈이 84.2%였다.
4. 偏側의 股勳脈과 股靜脈을 吻合하는데 所要된 時間은 皮膚를 縫合할 때까지 平均 2時間이었다.
5. 股動脈의 內膜再生은 2週경에 始作되어 3週에 完全히 再生되었으며 股靜脈은 훨씬 늦어서 4週后에도 再生되는 證據가 없었다.
6. 血管中膜의 壞死도 再生되지 않고 4週에서 그 範圍만 좀 줄어든 程度였다.

Microsurgery is a specialized surgical technique performed under the magnification of an operating microm iecoscop e ,
For the last 20 years , microsucgical technique and instruments have rapidly developed, which have made ceplantation of amputated digits or extremities and free tissue transfer possible
Nowadays microvasculac surgery is widely used in clinical practice with a remarkable success rate. But the histopathological changes at the anastomosed vessel wall is a key problem in miccovasculac surgery which is the most important factor causing thcombotic occlusion
If thrombosis in the anastomotic vessel can be prevented by reducing histopathological changes, the secret to obtaining perfect results of miccovasculac anastomosis will be known
For studying histopathological changes at the miccovasculac anastomotic site, We used femoral arteries and femoral veins of Lewis cats, Light microscopic and transmission electron microscopic observations were performed serially at 1 hour, days, 1 weeks, 3 weeks and 4 weeks after microvasculac anastomosis.
The results wear as follows
1. The external diameter of the cats femoral arteries was 0.4-1.0- of femoral veins
2. Anastomoses was completed ´with BV 75-3 10-0 monofilament nylon, interrupted 6-8 sutures for arteries and 6-10 sutures for veins
3. The patency rate was 97-4 Yo in femoral arteries and 84.2 % ´in femoral veins
4. The average time spent for anastomosis of one femoral artery and one femoral vein was about 2 hours,
5. The intimal regeneration in arteries began during the 2 nd week and was completed during the 3 rd week, but the veins had no evidence of intimal healing until the 4th week,
6. The medial necrosis was not regenerated, only in it´s extent, with in 4 weeks.
