Cavernosograms of a 67-year-old man in the superficial dorsal vein group. (A) While the tip of a 19-gauge scalp needle (white asterisk) was positioned in the right corpus cavernosum, the superficial dorsal vein (white curved arrow), the deep dorsal vein (white arrow) and the cavernosal vein (black arrow) were shown after injection of the contrast medium. The left femoral vein (white cross) was well-opacified; (B) those veins were enhanced while the para-arterial vein (arrowhead) was clearly shown; (C) the superficial dorsal vein (white curved arrow), the deep dorsal vein (white arrow), the para-arterial vein (white arrowhead) and the left femoral vein (cross) were still demonstrated despite the introduction of an artificial erection.
