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.
“…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 …”
Male 12-year-old patient presenting urethrorrhagia after straddle injury associated to hemodynamic instability secondary to traumatic formation of pseudoaneurysm of the pudendal artery in the bulb of the penis. Satisfactory treatment with angiographic selective and direct percutaneous embolization was performed, with resolution of the bleeding.

“…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.…”
Post-traumatic high flow priapism is a rare disease. A review of English published reports revealed 63 cases. Enhanced computed tomography (CT) of the penis has not previously been used as a diagnostic method for post-traumatic high flow priapism. We present a case of post-traumatic high flow priapism diagnosed with enhanced CT of the penis. Additionally, diagnostic modalities for post-traumatic high flow priapism are discussed with review of published work.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
