【摘要】 目的 探讨高原特殊地理环境如缺氧、生活习惯等和脂肪肝的关系。 方法 对平均海拔高度3 500m的西藏昌都地区64例CT扫描诊断为脂肪肝的病例进行分析。 结果 64例CT扫描均见肝脏实质密度减低,肝脾密度倒置。根据肝脾密度CT值改变程度与病变范围:重度14例、中度26例、轻度24例,其中CT表现为弥漫型43例,节段型14例,局灶型7例。44例饮酒史中超过10年以上34例,CT表现均为弥漫型。少于10年10例,弥漫型8例、有2例节段型。饮酒史超过10年又合伴肥胖的27例中脂肪肝改变,均为弥漫型CT改变。 结论 高原缺氧与肝脂肪变性有密切关系。更多还原

【Abstract】 Objective To explore the relationship between the CT findings of steatohepatitis and the special environmen-tal factors in highland area, such as anoxia and life styles. Methods CT scan was performed for 64 patients, who were 44 males and20 females in Tibet with a 3500-meter elevation. Results Hypodensity in liver parenchyma and the invertion of liver density andspleen density were found in all the 64 patients. According to the degree and scope in their pathological changes, these patients weredivided into three groups: severe 14, moderate 26, and mild 24.And diffused 43, sectional 14, regional 7 by CT findings. Among the44 drinkers, 34 with more than 10 years were diffused by CT scan, the other 10 drinkers under 10 years, diffused 8, and sectional 2.In addition, the 27 steatohepatitis patients were all diffused by CT who were obese and had drinked more than 10 years. Conclusionanoxia and drinking excessively in highland area are relevant to fatty degeneration in liver.更多还原
