在这项研究中,我们采用经颅多谱勒(TCD)检测了包括短暂性单眼失明(TMB)、视网膜中央或分枝动脉栓塞以及缺血性眼病在内的具有临床证据的视网膜缺血病人中脑微栓子的发生频率,并且评定了与颈动脉狭窄的相关性。 1993年3月29日至1996年7月31日期间,波士顿医学院神经血管研究所采TC-2000或TC-2020TCD仪,对331例病人的453条颅内动脉进行了微栓子信号(MES)的检测,除外其中颈动脉内膜切除术侧的大脑中动脉(MCAs),并删除资料丢失或不完整、伴有其他脑血管疾病及有心脏栓子来源的病例,对符合标准的163例病人的186条MCAs进行MES检测。 以44例同侧视网膜缺血病人的45条MCAs作为研究组,其中包括:单纯TMB病人的30条MCAs,TMB同时伴有同侧大脑半球缺血或梗死7例,视网膜中央
In this study, we used transcranial Doppler (TCD) to detect clinical evidence of retinal ischemia in patients with transient monocular blindness (TMB), central or branch retinal artery embolism, and ischemic eye disease The incidence of midbrain microemboli was assessed and the association with carotid stenosis was assessed. From March 29, 1993 to July 31, 1996, 453 intracranial arteries of 331 patients underwent micro-embolization (MES) with a TC-2000 or TC-2020 TCD instrument from the Neurovascular Institute at Boston College of Medicine ) Except carotid endarterectomy side of the middle cerebral artery (MCAs), and delete the data is missing or incomplete, with other cerebrovascular diseases and cases of cardiac emboli origin, to meet the standard of 163 cases 186 MAs of patients were tested for MES. Forty-four MCAs with ipsilateral retinal ischemia were included in the study, including 30 MCAs in TMB patients, TMB combined with ipsilateral hemispheric ischemia or infarction in 7 cases, central retinal
