Intravenous digital subtraction angiography was used to determine prospectively the
positional variations of the common carotid bifurcation in 100 consecutive patients with …

Color Doppler flow imaging is a new technique providing simultaneous display of a gray-
scale tissue and a color-flow vascular image. We demonstrate its ability to predict accurately …

Of the wide variety of clinical imaging modalities available to the zoo and wildlife medicine
practitioner, radiography and ultrasonography have the broadest applications. These …

Color Doppler ultrasound facilitates investigation of blood flow in addition to imaging
parenchymal abnormalities. To assess the clinical use of this technique we evaluated 25 …

The internal and external carotid arteries are usually considered occluded distal to a
common carotid artery occlusion but some collateral vessels may provide blood keeping the …

With common carotid artery occlusion there is usually no flow in the distal vessels. However,
flow to the ipsilateral internal common carotid artery may be maintained by collateral …

Cardiovascular diseases are a common cause of morbidity and mortality in subjects on
regular hemodialysis. Insulin resistance is associated with increased cardiovascular …

The blood flow may be diverted from the external to the internal carotid artery via the carotid
bulb in the absence of flow in the common carotid artery. We aimed to investigate the …
