大面积脑梗死首次CT征象31例分析

目的　观察分析大面积脑梗死首次CT征象改变。方法　对 31例大面积脑梗死病人 ,采用GE高速智能螺旋CT ,层厚 5mm ,连续扫描全脑。结果　发病≤ 6hCT等密度影者 9例 ,低密度影者 1例 ,二者比较差异显著 (P <0 .0 5 ) ;≥7h均为低密度影 ;低密度影者侧脑室受压 1 1例 ,中线移位 5例 ,梗死后出血 3例。结论　大面积脑梗死过早检查 ,CT不易全部表达 ,应根据病人症状和体征适时复查CT ,才能确诊

Analysis of the First CT Signs and Symptoms of Extensive Cerebral Infarction of 31 Cases

Objective To observe and analyze the change of the first CT signs and symptoms of extensive cerebral infarction. Methods In 31 cases with extensive cerebral infarction, to make continuous scanning to the full brain with GE high speed intelligence spiral CT with layer thickness 5 mm. Results In onset time≤6 h 9 cases had isopyknic image, 1 case had low density image. There was a marked difference between the two (P<0.05). In onset time≥7 h, all patients had low density image. Among them, 11 cases' lateral ventricles were pressed, 5 cases' median lines were translocated and 3 cases bled after infarction. Conclusion After extensive cerebral infarction, too early examination can not fully express through CT, according to the patient's signs and symptoms diagnosis can be made after reexamination with CT in proper time.
