The axial penile arteries are usually accompanied by venae comitantes.
Large communicating veins may originate from within the prepuce or from the retrobalanic venous plexus and then pierce the fascia penis to run in the subcutaneous tissues. They sometimes arise directly from the circumflex or deep dorsal median veins. They may be dorsal, dorsolateral, lateral, or ventrolateral, but converge to end in one or two dorsal median or dorsolateral trunks at the base of the penis.
A subdermal venous plexus extends from the prepuce to the base of the penis, where small venous trunks emerge to join either the communicating veins or the venae comitantes.
The communicating veins end in a variable manner. They may end in one saphenous vein, usually the left just before it enters the femoral, or they may divide and the branches join the corresponding long saphenous vein. The communicating veins or the venae comitantes may end directly in the femoral vein (□ Fig. 3.5).
