The definitive management of traumatic highflow priapism is by selective embolization with autologous blood clot. Nonischemic priapism, also known as high-flow priapism, is due to an unregulated or disrupted arterial inflow, allowing well-oxygenated blood in the corpora. Treatment of High-flow Priapism with Superselective Transcatheter Embolization in 27 Patients: A Multicenter Study - Journal of Vascular and Interventional Radiology Skip to Main Content This treatment often relieves pain, removes oxygen-poor blood and might stop the erection. Superselective embolization of terminal branches of the male internal pudendal artery is a highly successful procedure in the treatment of high-flow arterial priapism. Since this type of priapism can resolve spontaneously after weeks of healing, physicians will often take a watch-and-wait approach. Partin AW, et al., eds. 4 Distinguishing ischemic from non-ischemic priapism is critical, as management differs markedly.

We describe 4 cases of high flow arterial priapism, ranging from 1 week to 3 years in duration. 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. Color Doppler ultrasonography was repeated 1 day, 1 month, and 6 months after the operation. Less common than the low-flow type; in adults, 80% to 90% have a single fistula causing the priapism, but in children, 50% have multiple fistulas.3-5 high blood flow (non-ischaemic priapism), which is rarer, usually caused by trauma or injury to the genital area ; recurrent or intermittent (stuttering priapism), which can be either due to low or high blood flow, and is when you have recurrent, painful erections lasting around 2-3 hours at a time . Duplex sonography with pulsed Doppler analysis (with and without dynamic erection studies with vasoactive substances) and nocturnal penile tumescence (NPT) are usually performed as first-line studies. You may also need an injection in your penis to help decrease blood flow. Prevalence increases with age: 12% are younger than 59 years, 22% are 60 to 69, and 30% are older than 69.11 Ischemic priapism the result of blood not being able to exit the penis is an emergency situation that requires immediate treatment.
