Transcranial duplex doppler ultrasonography in dogs with hydrocephalus
Transcranial duplex Doppler ultrasound was performed in 32 conscious dogs presenting ventriculomegaly detected in B-mode, obtaining measures of lateral ventricles and resistance parameters of main cerebral arteries before and after 30 days of clinical treatment. The animals were distributed divided in two groups: group 1, dogs that presented remission or decrease of the neurological signs of th...
متن کاملTranscranial Doppler Ultrasonography in the Management of Neonatal Hydrocephalus
The pathophysiological changes of progressive neonatal hydrocephalus include: increased intracranial volume of cerebrospinal fluid, progressive dilatation of cerebral ventricles, decreased intracranial compliance, raised intracranial pressure, alteration of cerebral circulation and subsequent secondary brain tissue damage (decreased cerebral blood flow, hypoperfusion, ischaemia), alteration of ...
متن کاملVertebrobasilar transcranial color-coded duplex ultrasonography: improvement with echo enhancement.
BACKGROUND AND PURPOSE The diagnostic yield of vertebrobasilar transcranial color-coded duplex ultrasonography (US) is often hampered by insufficient acoustic penetration, anatomic variations, and vessel tortousity. The purpose of this study was to evaluate the effect of echo enhancement on vertebrobasilar transcranial color-coded duplex US. METHODS In 23 consecutive patients (mean age, 61.0 ...
متن کاملThe Evaluation of Microanastomoses in Rats with Color Doppler Ultrasonography
As microvascular surgery increases in popularity, the need for techniques to monitor the patency of small blood vessels after operation has assumed increasing importance. The ideal monitoring technique must be readily available, simple, quick, non-invasive and inexpensive and have a high accuracy rate. Harrison et al. have defined some of these properties of ideal monitoring, but currently ther...
متن کاملMeasurement of the blood flow velocity in the pericallosal artery of children with hydrocephalus by transcranial Doppler ultrasonography--preliminary results.
AIM The goal of this study was to evaluate selected parameters of the Doppler curve of the pericallosal artery at children with hydrocephalus. METHODS 12 patients with hydrocephalus were divided into two groups. Group 1 comprised children needing cerebrospinal fluid drainage, and group 2 comprised children without any indication for drainage or with an already inserted well-functioning draina...
