Reduced cerebrovascular CO(2) reactivity in CADASIL: A transcranial Doppler sonography study.
BACKGROUND AND PURPOSE Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukencephalopathy (CADASIL) is a hereditary angiopathy caused by mutations in Notch3. Cerebral microvessels show an accumulation of granular osmiophilic material in the vicinity of degenerating vascular smooth muscle cells. To study cerebrovascular function in CADASIL, we performed measurements on cer...
متن کاملEmbolic stroke by compression maneuver during transcranial Doppler sonography.
BACKGROUND AND PURPOSE Embolic complications during ultrasound examinations are a rare cause of neurological deficits. The present case documents the occurrence of embolism by a nonobstructive compression maneuver during transcranial Doppler examination, resulting in a minor stroke. CASE DESCRIPTION A 63-year-old man suffered from recurrent transient ischemic attacks. Duplex sonography showed...

متن کاملTranscranial Doppler in cerebrovascular disease.
Doppler analysis of flow in intracranial arteries is now possible using a 2 MHz probe allowing sufficient penetration of bone to obtain signals noninvasively. Thirty-two normal subjects, and 11 patients with cerebrovascular diseases including vasospasm following subarachnoid hemorrhage, middle cerebral artery stenosis, and extracranial internal carotid artery stenosis were studied by transcrani...
متن کاملA simple test to assess cerebrovascular reserve capacity using transcranial Doppler sonography and acetazolamide.
The goal of this study was the development of a simple bedside test to assess cerebrovascular reserve capacity using transcranial Doppler sonography. We studied 33 normal persons at rest and after stimulation of cerebral blood flow with 1 g acetazolamide. Their mean +/- SD increase in blood flow velocity in 54 middle cerebral arteries 10 minutes after stimulation was 24.4 +/- 9.2 cm/sec. We tri...
