[Experimental study of an axial vascularized pedicle flap induced in rats]

The authors report an experimental study about induced flaps in rats. The aim of this study is to determine that neoangiogenesis can be formed from surgically introduced pedicle. Two main groups were studied: in the first one the arteriovenous pedicle was be anastomased at its distal end, in the other, an arteriovenous loop was created microsurgically. In both groups we obtained good results and the flaps stayed alive. Neoangiogenesis from the surgically introduced axial pedicle was observed. The prospects in human pathology are interesting to consider, for the surgeon might be liberated from the narrow anatomic limits imposed by vascular territories, by creating a suitable flap anywhere in the body.
