[A microcirculation observation of the venous flaps].
This article presented the observation results of microcirculation of 84 island venous flaps performed on the ears of 42 rabbits. The survival rates of 5 groups divided by differently handling the vessel pedical of the flaps were: 1. maintaining artery and venous 90.36%. 2. maintaining distal and proximal venous 86.29%. 3. only maintaining proximal venous 75.71%. 4. only maintaining distal venous 28.75%. 5. ligating all vessels O(P < 0.01). The results of blood flow examined by laser Doppler and the number of micrangium counted by microcirculation microscope were decreasing upon the sequence of the above groups (P < 0.05). We found that there were exact microcirculation in the venous flaps of group 2, 3, 4, but the blood flow in these groups, especially the group 4, were slower than the group 1.
