Venogenic Erectile Dysfunction || Ultrasound || Case 313
Clinical Features:
A 42-year-old male patient came with erectile dysfunction.
Ultrasound Features:
- Both corpus cavernosa & corpus spongiosum appear uniform.
- Both cavernosal arteries are normal in diameter.
- Post-papaverine state shows increased systolic flow in cavernosal arteries.
- Persistent increase in diastolic flow indicating venous leakage.
Remember:
- This may be due to an excessive venous leak from the corpora cavernosa.
- The exact cause is not known.
- It is assumed that tunica albuginea stretches beyond the normal limit and thus cannot obliterate the emissary veins draining the sinusoids during the erection.
- Due to the inadequate compression of emissary veins the venous outflow is continuous & erection is never fully obtained.
- A venous leak is suspected when persistent high diastolic flow is seen in the cavernosal arteries & the diastolic flow is more than 5 cm/sec.
