Objective- Obtaining the normal images ofcolor doppler and estimation ofblood flow velocity parametersof femoral and axillary arteries in dog.Design- Descriptive studyAnimals- 7 healthy adult mixed-breed dogs, weighing 14.3 ± 2.8 kg (mean ± SD).Proceudure- Left and right femoral and axillary arteries of hind and forelimbs were evaluated. Colorand spectral doppler images ofthe each artery were o...
متن کاملDoppler study of cerebral arteries in hypercholesterolemia
BACKGROUND Hypercholesterolemia is one of the major modifiable risk factors for atherosclerosis of the coronary and carotid arteries. Although transcranial Doppler (TCD) studies of the cerebral arteries are indicative of decreased cerebral blood flow velocities in patients with hypercholesterolemia, the number of these studies has been limited. The aim of this study was to assess the hemodynami...
متن کاملEvaluation of ejection murmurs by pulsed Doppler echocardiography.
A common problem is a soft basal ejection murmur in an asymptomatic child with a normal electrocardiogram and chest x-ray films. If the diagnosis is aortic stenosis, there is a need for prophylaxis for subacute bacterial endocarditis and concern about development of calcific aortic stenosis. In 40 consecutive children referred for this differential diagnosis, aortic stenosis was diagnosed in 30...
متن کاملPre-ejection period by radial artery tonometry supplements echo doppler findings during biventricular pacemaker optimization
BACKGROUND Biventricular (Biv) pacemaker echo optimization has been shown to improve cardiac output however is not routinely used due to its complexity. We investigated the role of a simple method involving computerized pre-ejection time (PEP) assessment by radial artery tonometry in guiding Biv pacemaker optimization. METHODS Blinded echo and radial artery tonometry were performed simultaneo...
متن کاملThe transcranial Doppler of maternal cerebral arteries and the prediction of pre-eclampsia
Background: Pre-eclampsia is a major cause of maternal and perinatal death. Parameters derived from the Doppler waveform in different vascular beds have been studied as possible predictors of pre-eclampsia. Objectives: To assess whether second –trimester changes in transcranial Doppler parameters of normotensive pregnant woman are associated with the subsequent development of pre-eclampsia. Sea...
