ABSTRACT

We report a case of a patient who developed high-flow priapism following a Winter procedure performed for the treatment of low-flow ischemic priapism. During the creation of bilateral cavernosal-glandular shunts, the tip of the left dorsal artery was accidentally lacerated. A fistula developed through the shunt between the torn artery and the cavernosal sinusoids of the tip of the left corpus cavernosum. Gray-scale and Doppler sonography and angiography allowed diagnosis and guided the therapeutic approach.

ABSTRACT

High-flow priapism usually follows perineal or penile trauma with disruption of an intracavernosal artery. Angiographic embolization of the lacerated artery is currently considered the treatment of choice. The contribution of gray-scale and color Doppler ultrasonography (US) in diagnosis and treatment of 10 patients with high-flow priapism was investigated. In patients with recent arterial laceration, the cavernous tissue surrounding the arterial-sinusoidal fistula appears as a hypoechoic region with undefined margins. In long-standing priapism, this area is usually more regular and circumscribed, mimicking a pseudoaneurysm. Color Doppler US is highly sensitive for detection of the arterial-sinusoidal fistula that causes extravasation of blood from the lacerated cavernosal artery. After angiography, color Doppler US allows confirmation of both successful embolization by demonstrating disappearance or size reduction of the fistula and unsuccessful treatment by demonstrating patency of collateral feeding vessels or early recanalization of the embolized artery. Limitations of color Doppler US include underestimation of the number of accessory feeding vessels, which may become patent only after embolization of the main vascular supply, and difficulty in recognizing vessels that feed the fistula from the opposite side.

ABSTRACT

OBJECTIVES: To determine the long-term follow-up of treatment of high-flow priapism, we reviewed the case records of 10 patients who were examined by the Urologic Clinic in Trieste from 1995 to 1998. High-flow or arterial priapism is a fairly rare dysfunction, generally resulting from penile or perineal trauma. In some cases, the etiology remains unknown. METHODS: Trauma was reported in 6 of 10 cases. No etiologic causes were evident in the other patients. Nine patients underwent selective embolization during arteriography, and in 1 patient, corporotomy and ligature of the cavernous artery were performed. Color Doppler ultrasonography was repeated 1 day, 1 month, and 6 months after the operation. The determination of erectile function at a mean follow-up of 41 months (range 17 to 64) was performed using the International Index of Erectile Function. RESULTS: Postoperatively, color Doppler ultrasonography revealed the absence of recurrence in 6 patients. Fistula recurrence was detected in 4 of 9 patients treated with selective embolization (44%). In three of these patients, a second embolization procedure was conclusive. In 1 case (11%), three consecutive embolizations were not conclusive and surgical ligature of the dorsal artery and collateral at the emergence of the penile root, out of the corpus cavernosum, was required. Sexual function was completely preserved in 80% of patients. CONCLUSIONS: Pudendal angiography with superselective embolization is the treatment of choice. It is well tolerated and ensures a high preservation of premorbid erectile function.
