Horner’s综合征患者出现病灶对侧面部出汗和发红已有报道,最近报告胸部和肢体也出现上述症状。相应病变大多在第2级交感神经元,位于第1节胸髓。过去只有1例报告为延髓病变,却缺乏神经放射学证据。本文试图通过临床观察和应用皮肤交感神经反射电生理检测对上述研究做进一步证实。 1990～1993年间对5例经MRI证实的住院病人进行系统临床观察。病灶分别位于延髓上部、下橄榄体、锥体交叉水平。其中3例为单纯延髓外侧梗塞,1例延髓外侧伴小脑梗塞,1例延髓后侧伴小脑梗塞。采用Shahani和Knezevic—Bajada方法检查皮肤交感神经反射,时间分别在卒中后742～1184天内。通过计算平均潜伏期、平均波幅、潜伏期及波幅差异指数与对照组(10例)比较。所有病例无糖尿病和周围神经病,观察期内
Horner’s syndrome patients have been reported on the side of the face sweating and redness has been reported, the recent reports of chest and limb also have the above symptoms. Most of the corresponding lesion in the second level of sympathetic neurons, located in the first section of the chest marrow. In the past only 1 case reported as a medullary lesion, but lack of neuroradiological evidence. This article attempts to further confirm the above studies through clinical observation and application of skin sympathetic reflex electrophysiological detection. From 1990 to 1993, 5 patients with MRI-confirmed inpatients were systematically observed. Lesions were located in the medulla oblongata, olives, cone cross level. Three of them were simple bulbar medial infarction, one medial medulla oblongata with cerebellar infarction, and one medulla oblongata with cerebellar infarction. Skin sympathetic reflexes were examined using the Shahani and Knezevic-Bajada methods for 742 to 1184 days post-stroke, respectively. The average latency, mean amplitude, latency and volatility index were compared with the control group (n = 10). All cases were free of diabetes and peripheral neuropathy during the observation period
