Multiple vein grafts for microarterial repair: an experimental study.
The influence of multiple suture lines along a vein graft for arterial repair was evaluated in a microsurgical model. Forty-five rats were divided into three groups. The femoral artery was repaired using one vein graft in group I, two sequential vein grafts in group II, and three grafts in group III. Patency rates were evaluated at 48 h and 10 days, and found to be 100% in all three groups. In the present study, patency was not affected by the number of suture lines. These results suggest that the use of multiple vein grafts for microarterial repair may be safe in difficult cases.
