RESUMEN
The authors describe a rare and little studied form (distal) of spinal amyotrophy. 12 patients were placed under observation. A group of patients with symmetric distal pareses of the hands and legs has been distinguished. Patients with long existent distal monoparesis of the hand or leg are described. The role of EMG in the differential diagnosis is emphasized.

The technique and methodology of diagnosis of brachicephalic arterial lesions by means of ultrasonic dopplerography before and after roentgeno-endovascular dilatation are described. Angiographic and ultrasonic studies were conducted in 21 patients who were eventually subjected to roentgeno-endovascular dilatation (RED) of stenosed and occluded segments of aortic arch branches (atherosclerosis in 19 cases, and nonspecific aorto-arteritis in 2). The stenosis was located in the brachiocephalic trunk in 1 case, in the right internal carotid artery in another one and in the subclavian arteries in the rest: stenosis of the right subclavian artery in 4 patients and first-portion left-subclavian artery in 11, and occlusion of first-segment left subclavian artery in 4. The diagnostic capacity of ultrasonic dopplerography was 94% in detecting brachiocephalic arterial stenosis of 50% and more, while angiographic investigation was more reliable in detecting subclavian occlusions (4 cases). A few clinical examples of the diagnoses of lesions in aortic arch branches and treatment thereof by transcutaneous roentgeno-endovascular dilatation are quoted.
