Stasis-induced thrombosis of rat microvascular anastomosis.

The rate of stasis-induced thrombosis in the rat femoral artery at varying times following microvascular anastomosis, was evaluated by direct inspection as well as by light and electron microscopy. The rate of thrombosis decreased with increasing postoperative time intervals. This decrease appears to coincide with histologic evidence of growth of the neo-intima at the anastomosis site.
