[Blood flow in affected major arteries of head in hypertensive patients].
OBJECTIVE
To assess blood flow in intracranial internal carotid and vertebral arteries in patients with essential hypertension (EH) and hemodynamically insignificant atherosclerotic lesions and deformities of major arteries of the head (MAH).


METHODS
The blood flow was assessed in 55 untreated patients (mean age 53 +/- 1 years) with mild, moderate or severe hypertension. 20 healthy patients served control. Duplex scanning was performed using ACUSON unit.


RESULTS
Total blood flow (Q) in hypertensive subjects appeared significantly subnormal. It was less in patients with hemodynamically insignificant atherosclerotic stenosis and flexures of the carotid and vertebral arteries than in patients with affection of the carotid arteries only. Q in MAH was lower in smokers than in non-smokers.
