目的 :探讨短暂性脑缺血发作 (TIA )的临床表现、发病机理与脑梗死的关系。方法 :对 1994～ 2 0 0 2年所收集的 64例TIA病例的发作特点、影像学及预后进行回顾性分析。结果 :64例TIA病例中有 41例表现为肢体瘫痪 ,眩晕 4例 ,失语 15例 ,精神障碍 2例 ,半侧舞蹈样发作 2例。发作时头颅CT检查发现 3 9例基底节区有腔隙性梗塞灶 ,其余未发现明显的出血及梗塞病灶。64例中有 5 9例痊愈 ,5例发展为脑梗死 ,其中 2例死亡。结论 :TIA与脑梗死的关系密切 ,是脑梗死的特殊缺血半暗带期 ,及时治疗有助于防止大面积脑梗死的发生
Objective: To investigate the clinical manifestations, pathogenesis and the relationship of cerebral infarction in patients with transient ischemic attack (TIA). Methods: The characteristics, imaging and prognosis of 64 TIA cases collected from 1994 to 2002 were analyzed retrospectively. Results: Of 64 TIA cases, 41 cases showed limb paralysis, 4 cases of dizziness, 15 cases of aphasia, 2 cases of mental disorders and 2 cases of half-dance-like attacks. Head CT examination found 39 cases of basal ganglia lacunar infarction, the rest did not find significant bleeding and infarction lesions. Of the 64 patients, 59 were cured, 5 developed cerebral infarction, and 2 died. Conclusion: TIA is closely related to cerebral infarction and is a special ischemic penumbra of cerebral infarction. TIA can help prevent the occurrence of large-area cerebral infarction
