Brain circulation in cerebral transient ischemic attacks.
Cranial blood flow, mean cranial transit time and cranial blood volume were measured by the intravenous RISA technique in 10 patients with cerebral transient ischemic attacks (TIA) at the various time intervals from the onset of last attack. Cranial blood flow was subnormal in 5 out of 11 determinations and mean transit time trended to be prolonged in the diseased hemisphere in cases suggestive...
متن کاملCerebral circulation and norepinephrine: relevance of the blood-brain barrier.
The systemic administration of norepinephrine has minimal effects on the cerebral circulation, perhaps due to blood-brain barrier mechanisms. To test hypothesis, the cerebrovascular effects of norepinephrine beyond the blood-brain barrier were studied in anesthetized baboons, Intraventricular norepinephrine (40 mug/kg) resulted in significant increases in cerebral blood flow (40%), cerebral oxy...
متن کاملThalamonal and Cerebral Circulation
Sir,—We read with much interest the fin-: study by Drs Sari, Okuda and Takeshita (Brit. J. Anaesth. (1972) 44, 330) as it relates closely to our own work. As they state, Fitch and his colleagues (1969) reported that fentanyl and droperidol in combination cause a small reduction in intracranial pressure, suggesting that this might be due to a fall in c.b.f. and CMRo,. This led us to study the af...
متن کاملCerebral alveolar echinoccosis mimicking primary brain tumor.
We present a case of cerebral infestation by Echinococcosis multilocularis mimicking an infiltrative primary brain tumor. A heavily calcified mass invading the midbrain enhanced in a cauliflower-like fashion with small peripheral nodules present on MR imaging. Perfusion-weighted MR imaging revealed low relative cerebral blood volume within the calcified lesion and peripheral hyperemia. Single-v...
متن کاملThe Cerebral Circulation
This presentation describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands, and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic, and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases...
