脑卒中,特别是脑梗塞,是镰状细胞病患儿死亡的主要原因之一。如果能证明病人处于脑卒中的高危状态,输血疗法对于预防脑卒中的发生是非常有效的。由于经颅多普勒超声能测定颅内大动脉血流,颅内动脉的狭窄,可导致脑栓塞的发生,表现为颅内动脉血液流速增加。据此,作者对190例镰状细胞病患儿进行经颅多普勒超声检查,探讨多普勒超声用于预测镰状细胞病引起脑卒中的可行性。 Stroke, especially cerebral infarction, is one of the major causes of death in children with sickle cell disease. Transfusion therapies are very effective in preventing the onset of a stroke if the patient is proven to be at a high risk of stroke. Transcranial Doppler ultrasound can determine intracranial arterial blood flow, intracranial artery stenosis, can lead to cerebral embolism occurs, the performance of the intracranial artery blood flow increased. Accordingly, the author of 190 cases of children with sickle cell disease transcranial Doppler echocardiography, Doppler ultrasound used to predict the feasibility of sickle cell disease caused by stroke.
