minute, giving a mean intracarotid flow of 250ml/min. However, contrastangiographyand digital analysis of cine or video recordings indicate a much higher brief midstream systolic flow velocity. Similar recording techniques suggest diastolic volume flow of 19ml of blood per 100g of brain per minute...
MATERIALS AND METHODS :The following variables were measured in 160 subjects using radiofrequency data techniques: CCA-IMT, carotid distensibility (CD), local pulse-wave velocity (PWVβ), and stiffness (β). The subjects were divided into four age groups (30-39, 40-49, 50-59, and 60-69 ...
We evaluated duplex ultrasonographic velocity patterns from the common carotid artery in 156 patients with arteriographically verified internal carotid artery disease. Flow to zero during diastole in the common carotid was found in three groups of patients: (1) those with flow to zero in both comm...
To determine blood flow patterns in the common carotid artery and external jugular vein in cows before and after sedation achieved by administration of xylazine hydrochloride.30 clinically normal Swiss Braunvieh cows.A 5.0-MHz sector transducer was used to examine the common carotid artery and external...
Real-time impairment of ocular blood flow (OBF) under common carotid artery stenosis (CCAS) has not been ascertained. We aimed to longitudinally assess the impact of CCAS on OBF using a rabbit model. About 75% stenosis was created by tying the common carotid artery with a plastic mandrel ...
TCD of the middle cerebral artery (MCA) was done by EME TC-64B. A very low global CBF value of 28 + 5 (SD) ml 100 g-1 min -7 was found at baseline as compared to 55 ± 5 ml 100 g-1 min-1 in the normal controls. During 6% CO 2-inhalation and after acetazolamide ...
The ipsilateral ICA had lower but antegrade blood flow (Fig. 1e), while the contralateral ICA had normal blood flow (Fig. 1f). Eight patients had compensatory increased flow velocity in the V3 segment of ipsilat- eral vertebral artery (systolic velocity 120~150 cm/s, average velocity 80~...
(velocity) against time, and a real time continuous audio signal that will change in rhythm, frequency and amplitude according to normal cyclical alterations in blood flow. A number of widely used parameters are typically extracted from the graphical display8. This is done automatically by the ...
