Animals are little assailed by primary vascular disturbs, but all the lesions involve vascular trauma and intense or weak hemorrhage. In general lesions of big sanguineous vessels can be repaired by direct suture by anastomosis or artificial grafts. The aim of this study was to test Gallus domesticus trachea in substitution of canine femoral artery segment. For such, 16 adult dogs without defined race, healthy, of both the sexes were used. Synthetic wires of unabsorbing polypropylene were used in microsurgical anastomosis, with interrupt suture pattern. The surgical success was evaluated through the vessel patency verification in the first 20 minutes after the conclusion of anastomosis by patency test and in the 60 or 120 postoperative days it was evaluated through contrast angiography. The Gallus domesticus trachea can be used like segmentary substitute of femoral artery in dogs, independent of its conservation medium, however the patency maintenance is linked with observation time, in accord the statistical analysis.
