Key result
Interpositional vein grafts show similar patency to simple repair in rat femoral vessels.
Why the study?
This study establishes a controlled model to examine patency rates of simple, arterial and venous anastomoses compared to vein graft repairs in rat femoral vessels.

Should not change clinical microsurgery practice; hypothesis-generating for vein graft necessity in small vessels, pending clinical trials.
Do 10-mm interpositional vein grafts provide similar patency rates to simple repairs in a rat femoral vessel model?
p-value: p=0.560 (arterial), 0.862 (venous)
In a rat model, 10-mm interpositional vein grafts demonstrate equivalent patency rates to simple anastomoses for femoral artery and vein repairs.
Zhang et al. (1994) studied Microvascular vessel repair (n=162). 10-mm interpositional vein grafts vs. Simple femoral-vessel repairs was evaluated on Patency rates of arterial and venous repairs (p=0.560 (arterial), 0.862 (venous)). Repair of the rat femoral artery and vein using 10-mm interpositional vein grafts resulted in similar patency rates compared to simple repairs (p=0.560 for arterial, p=0.862 for venous).
