The relationship of arterial blood flow and venous volume to venous flow velocity was studied in normal subjects. The effects of current modes of treatment in venous thrombosis and of a vasodilator drug on venous flow velocity were also investigated. Total calf flow and venous volume were measured by venous occlusion plethysmography while venous flow axial velocity was determined by the transit...

BACKGROUND AND PURPOSE Transcranial Doppler blood flow velocities are inversely related to age and hematocrit, but the relative importance of age, oxygenation, and hemorheological factors has not previously been examined. We evaluated the relative contributions of these factors to middle cerebral artery blood flow velocity in adults with chronic renal failure, a population subject to significan...

Background and Purpose: Transcranial Doppler blood flow velocities are inversely related to age and hematocrit, but the relative importance of age, oxygenation, and hemorheological factors has not previously been examined. We evaluated the relative contributions of these factors to middle cerebral artery blood flow velocity in adults with chronic renal failure, a population subject to significa...

[Purpose] The purpose of this study was to correlate the talocrural range of motion (ROM) and blood flow velocity in the lower limb arteries of diabetic women. [Subjects and Methods] Thirty women were divided into a control group (G1), consisting of 15 sedentary right-handed subjects (41.27 ± 7.24 years old) who had no history of blood system disorder, and a diabetes group (G2), consisting of 1...

in order to identify left ventricular diastolic function in patients with betathalassemia major and normal systolic function by noninvasive m-mode and doppler echocardiography, an analytic study was designed in a university hospital in sari. we have studied 44 patients (23 men and 21 women), mean age 15.48±2.16 (range 12 to 20) and 43 age and sex matched control subjects. peak flow velocity in ...
