Abstract
BackgroundThis study aimed to report long-term outcome of superselective embolization in patients with high-flow priapism refractory to medical and surgical treatments.MethodsFrom August 2011 until July 2016, 14 patients with high-flow priapism refractory to local treatments were treated and their charts were retrospective reviewed. Clinical evaluation, color Doppler ultrasonography, arteriography and selective embolization were performed. Follow up was performed in all patients. Fourteen men (18–63 years old) were enrolled, with priapism duration of 14 h to 28 days. Internal pudendal arteries or glutaea inferior arteriae were successfully embolized with gelatin sponge particles, polyvinyl alcohol particles or microcoils.ResultsPseudoaneurysm in right femoral artery was found in one case after intervention. The follow-up 1 week later showed that 13 patients were in good condition, the priapism diminished 1–7 days (mean 3.2 ± 0.5 days) after intervention, and 1 patient received second intervention. Mean follow-up was (range 10.8–69.6) months. One patient had recurrent priapism months after embolization and had his penis surgically removed for severe necrosis.ConclusionsSuperselective embolization is safe and effective in high-flow priapism refractory local treatments, with a good long-term prognosis.
Highlights
This study aimed to report long-term outcome of superselective embolization in patients with highflow priapism refractory to medical and surgical treatments
A fundamental aim of priapism management is try to relieve penile ischemia/ anoxia and to prevent erectile dysfunction (ED) to achieve maximal preservation of sexual health [4].Surgery is the traditional method for high-flow priapism, this invasive treatment is less efficacious and associated with higher rates of ED compared with arterial embolotherapy [6]
Transarterial embolization is a useful alternative to surgery for high-flow priapism if local treatment fails [1, 7]
Summary
This study aimed to report long-term outcome of superselective embolization in patients with highflow priapism refractory to medical and surgical treatments. High-flow priapism is a rare condition, characterized by a prolonged and painless erection, which may permanently impair erectile function and should be treated timely to restore potency [5]. A fundamental aim of priapism management is try to relieve penile ischemia/ anoxia and to prevent erectile dysfunction (ED) to achieve maximal preservation of sexual health [4].Surgery is the traditional method for high-flow priapism, this invasive treatment is less efficacious and associated with higher rates of ED compared with arterial embolotherapy [6]. We report long-term outcome of superselective embolization in 14 cases with high-flow priapism refractory to medical and surgical treatments
