• The importance of cerebral vascular disease is well known as is its increasing frequency in all age groups. Progress in the clinical management of cerebrovascular disease has stemmed from increasing appreciation of the significance of deranged function in the arteries of the head and neck.' 3 There is a growing realization that the cerebral arteries may have a different physiological and morp...

BACKGROUND A child, who presented atypical haemolytic uraemic syndrome (aHUS) at the age of 1 month, developed cerebral ischaemic events at the age of 10 years. RESULTS Stenoses of both carotid arteries, left subclavian and vertebral arteries, several intracranial, right humeral, several coronary, and all pulmonary arteries were demonstrated. At the age of 13 years, left subclavian and right ...

In the evaluation of the extracranial carotid circulation for occlusive disease, duplex sonography was used routinely to determine the direction of flow in the vertebral arteries. Of 600 patients examined, 15 were found to have reversed flow in a vertebral artery-the subclavian steal syndrome. This was confirmed in the seven patients who underwent angiography. Duplex sonography was found to be ...

We report a case of cervicomedullary compression by an anomalous vertebral artery treated using microsurgical decompression with intraoperative monitoring. A 68-year-old woman presented with posterior neck pain and gait disturbance. MRI revealed multiple abnormalities, including an anomalous vertebral artery that compressed the spinal cord at the cervicomedullary junction. Suboccipital craniect...

BACKGROUND AND PURPOSE Global cerebral blood flow (CBF) is an important yet largely unknown quantity in the treatment of neurological intensive care patients. Color duplex sonography of the extracranial cerebral arteries can be used to measure global CBF volume directly at the bedside. To establish reference data on global CBF volume and to test the influence of sex and age on this parameter, a...

4 0 Years old male, non alcoholic, not a known hypertensive who presented with sudden onset of severe headache on 09.05.06. Neurological examination was normal. CT brain and MRI brain showed left frontal white matter and external capsule hemorrhage. Patient i m p r o ve d we l l. S i n c e p a t i e n t h a d recurrent attacks of headache, Digital subtraction angiography was done to look for an...

BACKGROUND Vascular calcifications and the bone fractures caused by abnormal bone fragility, also called osteoporotic fractures, are frequent complications associated with chronic kidney diseases (CKD). The aim of this study was to investigate the association between vascular calcifications, osteoporotic bone fractures and survival in haemodialysis (HD) patients. METHODS A total of 193 HD pat...

BACKGROUND AND PURPOSE When medication fails to improve symptoms of atherosclerotic stenosis of the intracranial vertebral and basilar arteries, percutaneous transluminal angioplasty (PTA) is considered. However, because investigators disagree on the usefulness of this procedure, we conducted a retrospective study to evaluate the indications, efficacy, and safety of PTA. METHODS Twenty patien...

Transient contractile responses to norepinephrine (NE) of vascular segments from the rabbit vertebral, internal carotid, and basilar arteries rise to a peak within several seconds, and in the presence of the agonist, reverse rapidly, relaxing with a half-time of 15 +/- 3.2 seconds. In the basilar artery, peak contraction is approximately 25% of the maximum response mediated via the "alpha-like"...

BACKGROUND AND PURPOSE Transcranial Doppler sonography is of established value in the detection and monitoring of middle cerebral artery vasospasm. Little information exists on the utility of transcranial Doppler for detection of posterior circulation vasospasm. METHODS Cerebral angiography and conventional hand-held transcranial Doppler sonography were compared to determine sensitivity and s...
