摘要
目的分析非创伤青壮年急性脑梗死的病因及CT影像特点。方法对23例青壮年脑梗死患者的临床与影像资料进行回顾性分析。分析梗死病灶的形态和部位特点,对治疗结果进行随访。结果长期酗酒者14例(61%);高血压并长期服用降压药者5例(21%);4例(18%)无明确诱因。23例中4例表现为腔隙性梗死(18%),3例表现为大脑中动脉区大面积梗死(13%),16例表现为不同形态的分水岭梗死(69%)。23例中18例治愈,5例明显好转。结论青壮年非创伤急性脑梗死的病因主要是高血压调控失当、脑内供血动脉闭塞或狭窄、长期酗酒、高血脂是诱因。CT显示青壮年脑梗死以动脉供血分水岭区脑缺血为主,预后良好。
Objective To explore the CT characteristics and etiology of non-traumatic cerebral infarction in young adults. Methods The clinical records and CT of 23 young patients with cerebral infarction were analyzed retrospectively. The shape and location of the infarcts were evaluated and the treatment outcome was reviewed. Results Of 23 patients, 14 （61%） had long-term history of alcohol consumption, 5 （21%） were on long-term anti-hypertensive treatment, 4 （18%） had no known risk. CT findings included lacunar infarction （4/23, 18%）, large cerebral infarction （3/23, 13%） and watershed infarction （16/23, 69% ）. Eighteen patients recovered completely and the remaining 5 patients showed marked improvement. Conclusion The most common causes of cerebral infarction in young adults include poorly-controlled hypertension with occlusion or stenosis of cerebral artery. Alcohol abuse and hypercholesterolemia were risk factors. Watershed cerebral infarction was more common with favorable prognosis in young adults.
