Vasculogenous impotence
From WikiLectures
Impotence - the inability to have an erection (erectile dysfunction), can be psychogenic or organic.
Arteriogenous impotence[edit | edit source]
Insufficient arterial inflow[edit | edit source]
- Central - arterial occlusion in the aortoiliac region.
- Peripheral - arterial occlusion of the branches of the pelvic arteries or directly the arteries of the penis.
- Other - arterial injuries in fractures of the pelvic bones, dysplasia of the deep arteries of the penis.
Therapy[edit | edit source]
- Reconstructive procedures on pelvic arteries (endarterectomies, bypasses).
- Or reconstructive procedures on penile arteries (epigastric-penile bypass).
- If they fail, implantation of penile endoprosthesis.
Phlebogenous impotence[edit | edit source]
- Increased venous outflow (insufficient blockage).
- Treatment by ligation or embolization of veins (v. dorsalis penis, v. penis profunda).
- Conservative treatment with vasoactive agents (relaxation of the smooth muscle of the feeding arteries) - prostaglandins, papaverine, sildenafil (Viagra®) = phosphodiesterase inhibitor.
