血流动力学性中风的发病机制探讨

Pathogenesis of hemodynamic stroke

为探讨血流动力学性中风的发病机制 ,对 2 3例血流动力学中风 (下称观察组 )患者的 CT、MRI检查结果及临床特点进行分析 ,并与非血流动力学性中风患者进行对照。结果显示 ,发病时平均收缩压观察组明显低于对照组 ,两组比较有显著性差异。观察组 CT、MRI检查示除 1例为脑干梗死外 ,余均为分水岭区梗死。提示在血流动力学性中风的发病机制中 ,血管狭窄性病变的程度和低血压状态可能起重要作用。

To explore the pathogenesis of hemodynamic stroke The image materials(CT and MRI)and clinic characteristic were analyzed in 23 patients (subject group)with hemodynamic stroke and compared with patiets(control group)with non-hemodynamic stroke The result showed that the mean systolic pressure of subject group was significantly lower than that of control group CT or MRI demonstrated watershed cerebral infarction in 22 of 23 patients in subject group The results suggest that the severity of vascular stenosis and hypotensive state may play an important role in pathogenesis of hemodynamic stroke
