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 its extent, with in 4 weeks.
