National Library of Medicine High-flow priapism: An overview of diagnostic and therapeutic concepts We describe the case of a 23 year-old man with high-flow priapism following blunt perineal trauma. Shearing forces on the endothelium cause release of increased levels of nitric oxide and activation of the cyclic guanosine monophosphate pathway, resulting in relaxation of smooth muscle.6-8 Advances in Urology. This branch most frequently replaces the dorsal artery of the penis and deep branches of the internal pudendal artery (with the internal pudendal artery terminating as the bulbar artery or with perineal branches). We describe 4 cases of high flow arterial priapism, ranging from 1 week to 3 years in duration. C, Computed tomographic angiography (CTA) 3D reformat of right pelvic side, showing an accessory pudendal artery (long arrows). Possible organic causes: vascular, neurogenic, hormonal, anatomic, drug-induced. Priapism is characterized by a permanent erection, not always totally rigid, and sometimes painful. A normal sexual erectile response results from the production of nitric oxide from endothelial cells after parasympathetic stimuli. The site is secure. In: Campbell-Walsh-Wein Urology.

Patients Included status is self-assessed. Ischemic or "low-flow" priapism occurs when blood disorders (such as sickle cell anemia or leukemia), prescription medication, or substance use cause the veins in the penis to constrict and keep blood from exiting the erection chambers (corpora cavernosa).

High-flow priapism is a nonsexual, persistent erection caused by unregulated cavernous arterial inflow. 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 Color Doppler ultrasonography was repeated 1 day, 1 month, and 6 months after the operation.

In rare cases, priapism may be related to cancers that can affect the penis and prevent the outflow of blood.

Use of angioembolization in urology: a review. Left untreated, blood vessels in the penis can rupture or the tissue can scar, leading to permanent erectile dysfunction. The internal pudendal artery arises from the anterior division of the internal iliac artery, with a typical trajectory curving under the sciatic notch that enables easy recognition.25 The artery enters the perineum via the lesser sciatic foramen and runs along the lateral wall of the ischiorectal fossa between the split layers of the obturator fascia in the Alcock canal to the inferior pubic ramus (Fig. Bookshelf Vol. doi: 10.23750/abm.v91i10-S.10233.

In some cases, the etiology remains unknown. Thus, the penis has three pairs of arteries: two urethral arteries that run on either side of the penile urethra in the corpus spongiosum, two cavernosal arteries, each running on the center of the corpus cavernosum, and two dorsal arteries of the penis running on either side of the dorsum of the penis between the tunica albuginea and Buck fascia, near the dorsal nerves of the penis. Evaluation of these vasculogenic factors ultimately depends on cavernosography and internal pudendal angiography.24. Typically a straddle injury to the perineum government site. 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. Nonischemic priapism, or high-flow priapism, occurs when there's continuous blood flow to the erectile tissue, but the blood flow is unregulated and doesn't become properly stored inside the penis. Posttraumatic nonischemic priapism treated with autologous blood clot embolization. Priapism is a persistent, usually painful, erection that lasts for more than four hours and occurs without sexual stimulation. Rigid penile shaft, but the tip of penis (glans) is soft.
