The reapplication of microvascular clamps after venous anastomosis: an experimental study

Albino rats were used to determine the effects of the reapplication of microvascular clamps in veins after anastomosis. The results demonstrate that, if necessary, microvascular clamps can be reapplied either proximal, or both proximal and distal to a venous anastomosis for up to 30 minutes, thus allowing a suture to be redone or the lumen to be explored with no loss of patency.
