近20年来,蛛网膜下腔出血(SAH)患者的结局已有显著改善,但仍有1/3的病人死亡或留下了后遗症,其最常见的原因是脑血管痉挛所致的迟发性缺血性神经功能损害(DIND)。经颅多普勒超声(TCD)是诊断脑血管痉挛的一种有效方法,本文旨在评价 SAH 后早期 TCD 检查对 DIND 的预测作用。121例病人经血管造影证实患有急性动脉瘤性SAH。DIND 的临床诊断是在 CT 和实验室检查排除再出血、脑积水、电解质失衡和心肺并发症等病变后作出的。在 SAH 后14天中,每日或隔日应用TCD 通过标准的经颢和经眶径路,记录大脑中动脉(MCA)。大脑前动脉(ACA)及颅外颈内动脉(ICA)
In the past 20 years, the outcome of patients with subarachnoid hemorrhage (SAH) has been significantly improved, but one third of patients still have died or left sequelae, the most common cause of which is late-onset cerebral vasospasm Ischemic neurological impairment (DIND). Transcranial Doppler ultrasound (TCD) is an effective method for the diagnosis of cerebral vasospasm. This paper aims to evaluate the predictive value of early TCD for DIND after SAH. 121 patients confirmed by angiography with acute aneurysmal SAH. The clinical diagnosis of DIND is made after CT and laboratory tests exclude rebleeding, hydrocephalus, electrolyte imbalances, and cardiovascular complications. In 14 days after SAH, middle cerebral artery (MCA) was recorded daily or on alternate days by standard TCD through the orbital path. Anterior cerebral artery (ACA) and extracranial internal carotid artery (ICA)
