Delayed high flow priapism: pathophysiology and management.

Two cases of the management and pathophysiology of high flow arterial priapism are presented. Both cases were post-traumatic with delayed onset of priapism and both had angiographically diagnosed arteriocorporeal fistulas. Case 1 was managed with selective cavernous artery ligation and case 2 resolved spontaneously, both with excellent return of premorbid levels of erectile function. We propose that the pathophysiological mechanism involves injury to the intracavernous artery, causing ischemic necrosis. After a delay the arterial segment blows out, leading to unregulated blood flow into the corpus cavernosum. Management with surgical ligation is highly selective and nondisruptive to unaffected vessels, offering precise control of the bleeding vessel.

False aneurysm of the facial artery.

A case of an unusual traumatic aneurysm of the facial artery secondary to blunt trauma is reported. The lesion was typical in that it was pulsatile, had a systolic bruit, and had a filling defect that was evident on carotid angiography. Although a traumatic aneurysm is a rare occurrence in the facial region, the inclusion of this lesion in the differential diagnosis of soft tissue lesions is important if the serious consequences of hemorrhage are to be avoided.

CT diagnosis of renal metastases.

Antemortum detection of renal metastases can be made by computed tomography (CT), particularly if the known primary malignancy is in a late stage. The CT scans of 10 oncologic patients with focal renal metastases were reviewed (confirmation by surgery in four, follow-up CT demonstrating new lesions or lesion growth in two). Five of our cases had only renal metastases and five patients had other areas of metastases. Renal metastases are well circumscribed, rarely enhance, and have density measurements of 25-70 Hounsfield units. Ways of differentiating these lesions from other renal masses are discussed.

Management of post-traumatic vascular malformations of the liver by catheter embolization.

Trauma to the liver occasionally produces vascular malformations, usually pseudoaneurysms of the hepatic artery and sometimes arteriovenous fistulas. Hemorrhagic complications, usually in the form of hemobilia, can result, and portal hypertension is a late complication of an arterial-portal vein fistula. The true incidence of these post-traumatic lesions is apparently much higher than previously realized, and they can regress spontaneously. A case is presented in which both complications appeared simultaneously after a stab wound to the liver. Treatment using selective arterial catheterization and embolization with thrombogenic material was successful. The literature on the use of catheter embolization in hepatic trauma is reviewed. We suggest that catheter embolization be added to the standard therapeutic armamentarium for these lesions. Selective catheter embolization is suggested as the initial therapeutic maneuver in treating both of these lesions because of the relatively low morbidity, the great precision available in limiting the area of devascularization and the good expectation of success on the basis of the reported results of this technique in other traumatized organs, as well as the initially promising reports of its use in hepatic lesions. It should be considered at the time of diagnostic arteriography.

Wandering spleen with torsion: appearance on CT and ultrasound.

Wandering spleen is a rare entity which may present with symptoms suggestive of other, more common abdominal processes. Torsion of the long pedicle may occur causing abdominal pain. This article describes a case of wandering spleen diagnosed by computed tomography (CT). Liver spleen scintigraphy and sonography supported this diagnosis and suggested torsion. To our knowledge this is only the second case of this entity in which color flow and duplex Doppler findings have been reported.

CT demonstration of empyema necessitatis.

Empyema necessitatis is a collection of fluid that has, by direct extension from the pleural cavity, penetrated the thoracic wall to form a mass in the extrapleural soft tissues of the chest wall. This is a rare condition and usually is associated with tuberculous effusion but may be associated with malignancy, blastomycosis, actinomycosis, and may even follow thoracentesis.
