[Estimation of the cerebral hemodynamics in patients with pathological kinking of arteries originated from the aortal arch according to angiography]. / Otsenka sostoianiia tserebral'noi gemodinamiki u bol'nykh s patologicheskoi izvitost'iu arterii, iskhodiashchikh iz dugi aorty, po dannym angiografii.

The state of cerebral blood flow was studied in 81 patients with chronic disorder of cerebral blood circulation using angiographic investigation. Various kinds of pathological kinking of the vessels, originated from the aortic arch, the reducing of their contrasting, the lowering of the blood flow velocity were disclosed. Enhancement of the capacity reserve of vascular channel while conducting the probe with sodium nitroprusside more than by 10% gave evidence about possibility of the blood flow restoration after reconstruction of the affected artery.
