Microvascular bypass grafts. Experimental study of pathologic changes in arterial and venous grafts.
Experimental autogenous grafts were made on adult Wistar rats using microvascular techniques. 3 months postoperatively, the grafts were controlled by angiography and by histopathological examination. We obtained a total patency rate of 52.7% and we observed that failure of the grafting can be explained by progressive hypertrophy of the walls of the vessels inducing thrombosis.
