目的探讨64排螺旋CT数字减影血管成像(MSCT-DSA)对诊断非高血压性脑叶出血病因的价值。方法17例脑叶出血患者,在脑出血的亚急性期进行MSCT-DSA检查,对减影后的数据进行最大密度投影(MIP)和容积再现(VR)技术重组,将17例脑叶出血MSCT-DSA检查的结果与手术病理和DSA检查结果进行对照。结果MSCT-DSA检查结果示,5例动脉瘤破裂出血,8例动静脉畸形破裂出血,1例海绵状血管瘤出血,2例脑转移瘤出血,1例脑血管形态未见异常,病理为脑血管淀粉样变。MSCT-DSA检查非高血压性脑叶出血病因的敏感性为100%,特异性为100%。结论MSCT-DSA在检查非高血压性脑叶出血病因中,能排除高密度血肿对造影血管的干扰,可提高非高血压性脑叶出血病因早期诊断的准确性。
Objective To investigate the value of 64-slice spiral CT digital subtraction angiography (MSCT-DSA) in the diagnosis of etiology of non-hypertensive cerebral hemorrhage. Methods Seventeen patients with cerebral lobar hemorrhage underwent MSCT-DSA in the subacute stage of cerebral hemorrhage. MIP and VR techniques were used to reconstruct the subtracted data. Seventeen patients with cerebral hemorrhage MSCT The results of the DSA examination were compared with those of the surgical pathology and DSA examinations. Results The results of MSCT-DSA showed that 5 cases had aneurysm rupture and hemorrhage, 8 cases had rupture of arteriovenous malformation, 1 case had cavernous hemangiomas hemorrhage, 2 cases had brain metastases hemorrhage, 1 case had no abnormal cerebrovascular morphology and pathological brain Vascular amyloidosis. MSCT-DSA non-hypertensive lobar hemorrhage etiology of the sensitivity was 100%, specificity of 100%. Conclusion MSCT-DSA can exclude the interference of high-density hematoma on contrast-induced blood vessels and can improve the accuracy of early diagnosis of non-hypertensive lobar hemorrhage in the etiology of non-hypertensive lobar hemorrhage.
