Percutaneous transluminal angioplasty for treatment of subclavian steal.

Twenty-two patients with subclavian steal were treated with percutaneous transluminal angioplasty (PTA). Fifteen had unilateral stenosis of the subclavian artery, one had severe stenosis on the left and total occlusion on the right, five had total subclavian occlusion on the left, and one had total occlusion of the innominate artery. All subclavian stenoses as well as the occluded innominate artery were successfully dilated, resulting in correction of subclavian steal; however, attempts to recanalize the totally occluded subclavian arteries failed.

Diagnosis of lipoma of the corpus callosum by CT in five cases.

The value of CT in the easy diagnosis of lipomas and associated anomalies of the corpus callosum, thus avoiding angiography and pneumoencephalography, is reported in five cases. An angiogram was performed in only one of the five cases and provided no additional diagnostic information.
