Microsurgical revascularization of the canine corpus cavernosum penis

The concept of vasculogenic impotence in humans is addressed by attempting to surgically create and correct vasculogenic impotence in healthy dogs. Initial experience reveals that only by extensive pelvic vascular interruption can such impotence be created and that, at best, it is only temporary because of collateralization. Microsurgical revascularization using both direct femoral artery implantation and femoral vein interposition into the corpus cavernosum penis yielded low patency rates. Further studies on this technique are needed before it can be recommended for widespread use in human beings.
