Myelolipoma of the liver.
A case of hepatic myelolipoma is described, including the angiographic and computed tomographic appearance. Only three such cases have been reported previously.

Diagnostic and interventional angiography in acute gastrointestinal hemorrhage.
The use of vasopressin infusion or arterial embolization in the treatment of 87 patients with gastrointestinal hemorrhage is reviewed. A bleeding point was identified angiographically in 46 patients (53%), with a higher success rate in those with upper gastrointestinal hemorrhage (63%) than in those with lower (39%) gastrointestinal hemorrhage. Vasopressin infusion in 33 patients completely stopped hemorrhage in 14 and slowed hemorrhage pending surgery in another 5. Gelfoam embolization was successful as definitive therapy in 12 of 15 patients. Mortality as a result of hemorrhage or its sequelae was 40% in patients with upper gastrointestinal hemorrhage and 21% in those with lower gastrointestinal hemorrhage.

Intracaval extension of pheochromocytoma ultrasonographic demonstration.
Pheochromocytoma is a relatively rare neoplasm, one which may also be found in association with other neoplasms. Preoperative demonstration of malignant pheochromocytoma into the inferior vena cava is uncommon. This is the first confirmed report of the ultrasonographic demonstration of inferior vena cava extension of a malignant pheochromocytoma. The coexistance of a primary bronchio-alveolar adenocarcinoma with this lesion has also not been previously reported.

Balloon dilatation of urethral strictures.
Postinflammatory and posttraumatic urethral strictures present a significant clinical problem. Conventional dilatation techniques are usually associated with recurrence and aggravation of the strictures. This is attributed to the mucosal and periurethral trauma associated with conventional dilatation methods. The initial results in seven patients undergoing balloon dilatation for urethral strictures are presented. The method is relatively atraumatic and painless, and better long-term results are anticipated.

Transcatheter gelfoam embolization in abdominal, retroperitoneal, and pelvic hemorrhage.
Clinical experience with Gelfoam embolization for arterial hemorrhage in 55 patients is described. This technique controlled hemorrhage in 51 patients (92.7%). Two patients (3.6%) died of complications related to embolization. Gelfoam can be a permanent occluding agent which does not require subselective catheter position for effectiveness and safety. The advantages of Gelfoam are its availability, low cost, the ease and speed with which it can be applied through conventional catheters, and its safety and effectiveness if properly applied. The data presented here, and those in the literature, indicate that transcatheter therapeutic embolization for arterial bleeding below the diaphragm is by far the safest and most effective method available.

The parathyroid artery.
Each parathyroid gland is supplied by a single individual artery, the parathyroid artery. Although discovered over 80 years ago, this fact has been ignored in anatomic texts and angiographic literature. The origin and length of the parathyroid artery very with the location of parathyroid tissue. If the parathyroid tissue is located posterior or caudal to the thyroid gland in the lower neck or mediastinum, the parathyroid artery arises as a prominent proximal branch of the inferior thyroidal artery. In this situation it is easily recognizable angiographically and can be useful in identifying low-lying parathyroid lesions. Of 35 angiograms obtained in 19 patients, the parathyroid artery supply in another low cervical and a mediastinal lesion. In two lesions, one of which was intrathyroidal, the blood supply was indeterminate. The parathyroid artery was recognized in eight of nine low cervical or mediastinal parathyroid lesions, but only in four of 10 lesions at or above the thyroid level. The parathyroid artery does not contribute to thyroidal blood supply.

Transcatheter gelfoam embolization in intractable prostatic bleeding.
The authors describe a case in which protracted bleeding after a transurethral prostatic resection could not be controlled with repeated fulguration and resection. Hemostasis was obtained with transcatheter arterial Gelfoam embolization of both hypogastric arteries.
