[Application of omental pedicle to tracheal allotransplantation: an experimental study using adult mongrel dogs].

Methods and results of experimental tracheal allotransplantation using adult mongrel dogs are described in this paper. Omental pedicle flap was used to reconstruct the vascularity of ischemic tracheal allograft. Twenty out of 22 allografts were found to be viable with almost normal tracheal structure and no granulation or stricture. The allografts were proved to be well revascularized from the omental pedicle flap by injection of Indian ink from the right gastroepiploic artery.
