Superselective Microcoil Embolization of a Traumatic Pseudoaneurysm of the Cavernosal Artery

Abstract

According to the literature, straddle injuries of the perineum may result in arteriosinusoidal fistula and secondary high-flow priapism. We report a case of a 23-year-old man who developed a traumatic pseudoaneurysm of the cavernosal artery, secondary to straddle injury, and presented with painless priapism. It was treated successfully with superselective microcoil embolization and the priapism resolved.

Urethrorrhagia Secondary to Traumatic Penile Pseudoaneurysm

“…Pseudoaneurysm formation as cause for urethral bleeding is an extremely uncommon event, with few published cases. Formation of this pseudoaneurysms in internal pudendal arteries and their branches are described for external trauma as much as traumatic catheterization, 2 , 3 , 4 but urethrorrhagia, also present in some cases, was attributed to urethral trauma and not to pseudoaneurysm, 5 which is only described in one previous case. 6 …”

Post‐traumatic high flow priapism: Demonstrable findings of penile enhanced computed tomography

“…Sixty‐three cases have been reported and almost all the cases were diagnosed based on the findings of blood gas analysis of cavernous body, color flow Doppler ultrasound and/or internal pudendal arteriography (Table 1). 3–36 In the 63 cases, high flow priapism was diagnosed using blood gas analysis in 11 cases (17.5%); color flow Doppler ultrasound in 44 cases (69.8%); and internal pudendal arteriography in 58 cases (92.1%). Blood gas analysis is quite useful because it can be done without specific tools.…”
