Symptoms of penile arteriovenous fistula

summary

Penile venous leakage is a condition in which the blood leaks to the glans or other blood vessels when the penis is congested due to the damage of the cavernous body in the penis. The symptom of arteriovenous fistula of penis tells everybody.

Symptoms of penile arteriovenous fistula

When the venous system of the corpus cavernosum is abnormal, the internal pressure of the corpus cavernosum can not reach 80 mmHg, or the venous return system of the corpus cavernosum can not be effectively closed, so the venous return can not be effectively reduced in the process of erection, and a large amount of blood leaks from the veins, which makes the penis unable to erect normally or insufficiently.

The occurrence of venous leakage is often caused by the abnormal mechanism of the passive compression and closure of the penile subthalamic vein, including the incomplete relaxation of the smooth muscle of the corpus cavernosum, the abnormal neural control, and the loss of elasticity caused by the fibrosis of the corpus cavernosum.

Congenital penile veins are too thick or too many, and there are abnormal communicating branches between the corpus cavernosum and the urethra cavernosum. It is common in congenital malformations or patients with penile persistent erectile disease who have undergone shunt surgery. When the patients were selected, the arterial response was good according to Doppler ultrasound; The effect of cavernous injection therapy and vacuum negative pressure device is not good; Quitters; There were no severe systemic diseases such as diabetes and arteriosclerosis; They were younger than 60 years old. It is very helpful to determine the route of venous leakage and determine the operation method to repeatedly measure the pressure of the corpus cavernosum or take photos of the corpus cavernosum before operation.
