Penile Artery Shunt Syndrome (PASS) is an iatrogenic clinical phenomenon first described by Tariq Hakky, Christopher Yang, Jonathan Pavlinec, Kamal Massis, and Rafael Carrion within the Sexual Medicine Program in the Department of Urology, at the University of South Florida, and Ricardo Munarriz, of Boston University School of Medicine Department of Urology in 2013. It may be a cause of refractory Erectile Dysfunction in patients who have undergone Penile Revascularization Surgery. == Description ==
Penile Artery Shunt Syndrome (PASS) was initially described in a patient who underwent Penile Revascularization Surgery for isolated left cavernosal artery stenosis in the absence of systemic vascular risk factors. An end-to-end anastomosis of the left inferior epigastric artery to the left dorsal penile artery was created using a previously described technique. After technically successful revascularization surgery, the patient continued to have post-operative erectile dysfunction despite documented patency of the surgical graft by Penile Duplex Ultrasonography. Pelvic angiography was performed on the patient, revealing an aberrant obturator artery originating from the inferior epigastric artery. The study revealed markedly sluggish forward flow visualized through the anastomosis to the left dorsal penile artery, with dominant flow in the left inferior epigastric artery to the obturator artery and its branches. This culminated in reduced blood flow to the penis.
