The deep dorsal vein of the penis drains oxygen-depleted blood away from the glans, which is the external head of the sexual organ. This vein runs the length of the shaft and it eventually flows into the prostatic venous plexus near a man's prostate gland. From there, the deoxygenated blood must travel through the venal system until it arrives at the center of the circulatory system for resupply with oxygen in the lungs and recirculation through the left side of the heart. The vein is not the same as a similarly named artery, which transmits oxygenated blood to the glans. However, the deep dorsal vein of the penis runs a course close to its arterial counterpart.
In human anatomy, the dorsal veins of the penis comprise the superficial dorsal vein of the penis and the deep dorsal vein of the penis. The superficial dorsal vein of the penis drains the prepuce and skin of the penis , and, running backward in the subcutaneous tissue , inclines to the right or left, and opens into the corresponding superficial external pudendal vein , a tributary of the great saphenous vein. In contrast to the deep dorsal vein, it lies outside Buck's fascia. It is possible for the vein to rupture, which presents in a manner similar to penile fracture. The deep dorsal vein of the penis lies beneath the deep fascia of the penis ; it receives the blood from the glans penis and corpora cavernosa penis and courses backward in the middle line between the dorsal arteries ; near the root of the penis it passes between the two parts of the suspensory ligament and then through an aperture between the arcuate pubic ligament and the transverse ligament of the pelvis , and divides into two branches, which enter the vesical and prostatic plexuses. The deep vein also communicates below the pubic symphysis with the internal pudendal vein. From Wikipedia, the free encyclopedia.
Soft Tissue Lumps - A Case of Thrombosis of the Deep Dorsal Vein of the Penis
There are many case reports of thrombosis of the superficial dorsal vein of the penis, but thrombosis of the deep dorsal vein of the penis is much more unusual. Ultrasound for soft tissue lumps is commonplace in every radiology department and a case such as this could cross any sonographers list. This case study will document a spontaneous presentation of venous thrombosis of the deep dorsal vein of the penis, presenting as a palpable lump via the General Practitioner and document pictorially the differentiating factors.
Dorsal vein thrombosis is a rare disease with pain and induration of the dorsal part of the penis. The possible causes comprise traumatism, neoplasms, excessive sexual activity, or abstinence. The differential diagnosis must be established with Sclerotizing lymphangitis and peyronies disease and doppler ultrasound is the imaging diagnostic technique of choice.
