Low-flow priapism is caused by decreased outflow of blood due to venous thrombosis; thus there results a compartment syndromelike pathophysiology, with the risk of gangrene. Materials and Methods: Between May 1994 and October 2006, 27 patients underwent superselective embolization of the cavernous artery for HFP. 1 Typically, the penis is neither fully rigid nor painful in this condition, and trauma is the most commonly reported etiology. Priapism is prolonged erection that persists beyond or is unrelated to sexual stimulation. If a person receives treatment within four to six hours, the erection can almost always be reduced with medication.

Ischemic priapism is comparable to a compartment syndrome causing hypoxia of the corpora cavernosa that is typically painful and requires emergent intervention to preserve erectile function. Acute onset of severe pain, rigidity, and other compartment syndrome clinical findings are noted. It is well tolerated and ensures a high preservation of premorbid erectile function.
