Regional redistribution of blood flow in the external and internal carotid arteries during acute hypotension.
The present study examined to what extent an acute bout of hypotension influences blood flow in the external carotid artery (ECA) and the corresponding implications for blood flow regulation in the internal carotid artery (ICA). Nine healthy male participants were subjected to an abrupt decrease in arterial pressure via the thigh-cuff inflation-deflation technique. Duplex ultrasound was employe...

متن کاملCharacteristics of the responses of isolated and perfused canine splenic arteries to vasoactive substances and to periarterially electrical stimulation.
Pharmacological characteristics of the canine isolated splenic artery were investigated by the cannula insertion method for observing vascular responses to vasoactive agents and periarterial nerve stimulation. Four alpha-adrenoceptor agonists and tyramine induced vasoconstrictions in a dose-dependent manner, and the order of potency was noradrenaline (NA) > phenylephrine > clonidine > methoxami...
متن کاملAtypical Arteritis in Internal Carotid Arteries: A Novel Concept of Isolated Internal Carotid Arteritis
We presented a 38-year-old woman suffering from acute cerebral infarction due to arteritis limited to bilateral internal carotid arteries without a condition of giant cell arteritis or granulomatosis with polyangitis. Our case is unprecedented and characterized by a young woman with wall enhancement in the internal carotid arteries on contrast-enhanced magnetic resonance imaging (MRI), therapeu...
متن کاملBilateral aberrant internal carotid arteries with bilateral persistent stapedial arteries and bilateral duplicated internal carotid arteries.
A 5-year-old boy was evaluated for a left retrotympanic mass found at otoscopy. Subsequent petrous bone CT and MR angiographic examinations demonstrated bilateral aberrant internal carotid, bilateral stapedial artery persistence, and bilateral duplicated internal carotid arteries. Imaging findings and their clinical relevance are discussed. A second case of unilateral aberrant internal carotid ...
