high flow priapism

Endovascular

treatment of a post-traumatic priapism case. Left arterio-cavernous fistula (circle) originating from the left cavernosal artery (black arrow). Large white arrows: Internal pudendal artery; White arrowhead: Perineal scrotal artery; Thin white arrow: Penile artery; Black arrowhead: Dorsal artery of penis.

Endovascular

treatment of a post-traumatic priapism case. No collateral branches feeding the fistula (circle) are identifiable. Black arrow: Cavernosal artery; Large white arrows: Internal pudendal artery; White arrowhead: Perineal scrotal artery; Thin white arrow: Penile artery; Black arrowhead: Dorsal artery of penis.

Endovascular

treatment of a post-traumatic priapism case. After embolization: Contrast reflux into and patency of the left dorsal artery of penis (black arrowhead), left penile artery (thin white arrow) and left perineal scrotal artery (white arrowhead).

Superselective

embolization for high-flow priapism refractory to medical and surgical treatments. The treatment for case 1. One pseudoaneurysm was shown in right internal pudendal artery by ultrasonography (a) and angiography (b). Right internal pudendal artery was successfully catheterized (c), embolization of its branches was performed microcoils of 2 mm*2 cm (d), and pseudoaneurysm disappeared (e). The left internal pudendal artery was normal (f)

Superselective

embolization for high-flow priapism refractory to medical and surgical treatments. The treatment for case 2. Right internal pudendal artery was catheterized (a) and its branches were embolized with gelatin sponge particles of 350-560um (b). Left internal pudendal artery was catheterized and external iliac artery shown (c), microcoils of 3 mm*3 cm were used for embolization its branches (d)

Right internal pudendal artery was catheterized (a) and its branches were embolized with gelatin sponge particles of 350-560um (b). The left external iliac artery was catheterized for left internal pudendal artery (c), gelatin sponge particles of 350-560um were used for embolization its branches (d)
