[Roentgeno-endovascular dilatation of the brachiocephalic arteries]

The article describes the technique of radiological endovascular dilatation (RED) of stenosed brachicephalic arteries. RED was attempted in 28 arteries (18 subclavian, 7 vertebral, 2 common carotid and 1 internal carotid) in 22 patients. In one patient RED of the third portion of the left subclavian artery was supplemented with endovascular prosthesis--transcutaneous transcatheter introduction at the site of the previous stenosis of a spiral-shaped prosthesis from nitinol (a nickel-titanium alloy). Technically good results of dilatation was achieved in 21 of the 22 patients, clinical effect in 20 patients. Some angiographic criteria of the selection of patients for RED of the brachicephalic arteries are described.
