Abstract

The paper deals with the condition of intracerebral hemodynamics in patients with occlusive lesions of major extracranial cerebral arteries studied with transcranial Doppler sonography (TCD). A total of 30 patients were studied: 19 with occlusion of internal carotid artery (ICA) or common carotid artery (CCA), 11 with uni- and bilateral kinking. Clinical examination, ultrasound Doppler sonography and Duplex examination of extracranial arteries, TCD, and cerebral angiography were applied. The data suggest that the degree of the developing brain ischemia and the character of clinical manifestations depended on the functional capacities of collateral circulation. Its possible sources and pathways in cases of occlusion of major cerebral arteries are discussed.

摘要

本文探讨经颅多普勒超声（TCD）研究的主要颅外脑动脉闭塞性病变患者的脑内血流动力学状况。共研究了30例患者：19例颈内动脉（ICA）或颈总动脉（CCA）闭塞，11例单侧和双侧血管迂曲。采用了临床检查、超声多普勒超声和颅外动脉双功超声检查、TCD以及脑血管造影。数据表明，脑缺血发展程度和临床表现特征取决于侧支循环的功能能力。文中讨论了大脑主要动脉闭塞时其可能的来源和途径。
