Autologous blood clot embolisation in posttraumatic high-flow priapism

Abstract

Non-ischemic, high-flow priapism is defined as the state of painless and permanent erection of the penis which generally develops by perineal trauma. Selective transarterial embolisation is one of the treatment options. We present an 18-year-old men who had complaints of painless and permanent erection after a blunt perineal trauma. Colour Doppler ultrasound revealed a pseudoaneurysm and fistula at the left cavernosal artery. Hence autologous blood clot injection was performed to embolise the pseudoaneurysm. Due to the recanalization on the postprocedural seventh day, second embolisation was performed. One month after the second procedure, colour Doppler ultrasound revealed a 50% shrink but mild refilling in the pseudoaneurysm, whereas complete thrombus formation was observed on follow-up imaging. His priapism had fully recovered and erectile functions were totally normal at the six months and one year follow up. Autologous blood clot embolisation seems as a safe and successful treatment.

Autologous Blood-Clot Embolisation of Iatrogenic Femoral Artery Pseudoaneurysm Caused by Arterial Sheath Placement; A Case Report

“…10,15,17 Emin Ozbek et al reported a case of proximal partial priapism which was treated successfully with ABC embolisation 15 Guliz Yilmaz et al reported a case of painless priapism due to PA and fistula of the left cavernosal artery as result of a trauma, which fully recovered by trans-arterial embolisation of ABC. 17 Also in other studies performed with a larger group of patients, this method had the effectiveness of 100%. 15 In 1975, Miller et al reported a successfully treated PA of the internal maxillary artery that resulted in active bleeding, with catheter embolisation of ABC.…”

A case of proximal partial priapism successfully treated with autologous clot embolisation

“…It has been reported to be effective of autologous clot embolisation in the treatment of high‐flow partial priapism in the literature (Akpinar & Yilmaz, ; Cantasdemir et al, ). Here, we treated our patient with autologous clot using superselective transcattheter embolisation.…”

Superselective embolization for high-flow priapism refractory to medical and surgical treatments

“…Although reabsorbable materials have traditionally been the most commonly used, the choice of embolic agent remains inconsistent [6,13] including autologous blood clot [14], gelatin sponge particles, polyvinyl alcohol [15], coils and N-butryl cyanide (NBCA) [6,14], and Ethylene-vinyl alcohol copolymer (Onyx®) [3]. Autologous blood clot, a temporary occlusive agent, is very effective for treatment of high-flow priapism and permits restore normal blood flow after absorption [5,6,14,16,17]. Lloret et al describe two cases of patients with high flow priapism treated by using non-reabsorbable materials of microcoil embolization [12].…”
