血管痉挛是蛛网膜下腔出血(SAH)患者死亡和致残的最主要原因。经颅多普勒超声照相(TCD)能非侵袭性地检测动脉的狭窄,但其灵敏度和特异性在血管造影的血管痉挛高频患者人群中未见报道。本文研究34例 SAH 后血管痉挛最大危险期(3～13d)以 TCD 和脑血管造影两种检查间的相互关系,和检查制定血管痉挛诊断经颅多普勒标准的效用。除外下列患者:血管造影表现为非动脉瘤引起的 SAH,在血管图诊断后24h 内未作 TCD 者,TCD 技术不足者,或在血管痉挛危险期未作相关的血管图者。以 TCD 检查如大脑中动脉(MCA)时间平均流速>120cm/sec 者,
Vasospasm is the leading cause of death and disability in patients with subarachnoid hemorrhage (SAH). Transcranial Doppler ultrasonography (TCD) can be non-invasive detection of arterial stenosis, but its sensitivity and specificity in the angiographic high-frequency group of patients with vasospasm have not been reported in the crowd. In this paper, 34 cases of SAH vasospasm after the most dangerous period (3 ~ 13d) TCD and cerebral angiography between the two checks the relationship between the inspection and development of vasospasm diagnosis of transcranial Doppler criteria utility. The following patients were excluded: Angiography showed non-aneurysm-induced SAH, no TCD within 24 hours after diagnosis of vascular map, under-diagnosis of TCD, or no relevant angiogram in the risk of vasospasm. TCD examination, such as the middle cerebral artery (MCA) time average flow rate of> 120cm / sec,
