A comparison of rapid-healing prosthetic arterial grafts and autogenous veins.
The patency rates and healing characteristics during a nine-month period of internal velour Dacron grafts, external velour Dacron grafts, and Sparks-Mandril grown grafts were compared with autogenous jugular veins when used to bypass short segments of the canine femoral artery. Graft thrombosis occurred in three of 11 external velour grafts, in six of 11 internal velour grafts, and in three of 11 Sparks-Mandril grafts, None of 33 autogenous veins occluded. Graft thrombosis was not correlated with the degree of graft healing but rather with a hyperplastic proliferative intimal lesion observed at the proximal anastomosis of the occluded grafts.
