VASCULAR VARIANTS IN PENIS ARTERIAL CIRCULATION

It is acepted that penis corpora cavernosa are irrigated by two cavernous arteries coming from the pudendal internal arteries that with the dorsal arteries are the terminal branches of the penis.

In some patients there are intracavernous ramifications of the cavernosus arteries, but nobody has studied these variations.

We present our study in patients (N400+) explored for suspicion of penis pathology, mainly Peyronie’s disease, congenital curvature and erectil dysfunction, penis Dynamic Doppler exam, with prostaglandin used.

Type I.- Two cavernosus arteries (CA) without anatomosis.

Type IA.- The classical anatomy described with two well developped CA.

Type IB.- Two arteries bad or developed, very thin without distension in the poststimulus phase.

Type IC.- One of the two cavernous arteries underdeveloped, with asymmetry of the CA.

Type II.- With the presence of functional intercavernosus anatomosis.

Type IIA.- One of the CA it is hypoplastic, underdeveloped, and it is supported by one or more intercavernous anatomosis with flow from the well developed to the hypoplastic one.

Type IIB.- One of the CA it is divided in two segments and the proximal one only irrigates the proximal third of the corpora cavernosa, the two thirds of the same corpora cavernosa are irrigated by one or more intercavernous anatomosis coming from the other c artery.

Type III.- With the presence of dorsocavernous anastomosis.

Type IIIA.- One of the two CA it is divided in two segments, proximal and distal, and the distal one depends of one dorsocavernous anastomosis that give irrigation to it. The proximal segment can be well or underdeveloped.

Type IIIB.- Both CA are divided in two segments, the proximal and the distal.

Type IV.- Both CA are divided in two segments, proximal and distal, and one of the distal are irrigated by a dorsocavernous anastomosis and the other distal by an intercavernous anatomosis coming from the other distal.

Type V.- Both CA have ramificacions and irregular intercavernous anatomosis.

These variation answer why patients respond or dont to medical treatment when they compensate their defficiency.

NO CONFLICT.
