Sherpa, Mingma Thsering, and Raksha Shrestha. Stroke at high altitude in an experienced Sherpa climber: A case report. High Alt Med Biol. 21:406–408, 2020.—A 44-year-old experienced Sherpa climber had dizziness with nausea and several episodes of vomiting while at Camp 2 of Mount Everest (6400 m). He was airlifted from Everest Base Camp to Kathmandu for further treatment. Neurological assessment revealed cerebellar signs with ataxia. Sensory examination revealed hypoesthesia on the extremities of the left side and right half of the face. Laboratory workup revealed increased hemoglobin and hematocrit levels. Magnetic resonance imaging of brain revealed ischemic infarction of right cerebellar hemisphere in the right posterior inferior cerebellar artery territory extending to medulla. Patient was managed with aspirin, supportive measures, and physiotherapy, and made a complete recovery after 2 months. This is the first documented case of ischemic stroke in a healthy experienced Sherpa climber. Although the exact cause of stroke in our patient remains uncertain, the prothrombotic state due to high altitude compounded by impaired cerebral autoregulation and dehydration may have been contributory factors.

经验丰富的夏尔巴登山者在高海拔中风：病例报告

夏尔巴人（Sherpa），明玛（Mingma Thsering）和罗刹（Raksha Shrestha）。一位经验丰富的夏尔巴登山者在高海拔中风：病例报告。高替代医学。2020年21：406–408。—一位44岁的经验丰富的夏尔巴人登山者在珠穆朗玛峰2号营地（6400 m）时头晕恶心，并呕吐了几次。他被从珠穆朗玛峰大本营空运到加德满都进行进一步治疗。神经学评估发现小脑体征伴有共济失调。感官检查显示面部左半边和右半边感觉不足。实验室检查发现血红蛋白和血细胞比容升高。脑部的磁共振成像显示右小脑后下动脉区域延伸至延髓的右小脑半球缺血性梗塞。患者接受了阿司匹林，支持措施和物理治疗，并在2个月后完全康复。这是一名健康的经验丰富的夏尔巴登山者首次记录到缺血性中风。尽管我们患者中风的确切病因尚不确定，但高海拔引起的血栓形成状态加之脑自动调节和脱水功能受损可能是促成因素。
