摘要
目的分析缺血性卒中患者颅内外动脉狭窄的分布。方法收集我院缺血性卒中患者306例,所有患者均进行颈动脉彩超、经颅多普勒超声(TCD)、磁共振血管造影术(MRA)和数字减影血管造影(DSA)检查,狭窄程度按北美症状性颈动脉内膜切除试验(NASCET)测量标准分为5个等级。结果(1)颅内动脉狭窄149例(48.6%),颅外动脉狭窄25例(8.2%),颅内外动脉均见狭窄33例(10.8%);(2)207例动脉狭窄患者中,单支狭窄129例(62.3%),多支狭窄78例(37.7%);(3)动脉狭窄的常见部位依次为:大脑中动脉>椎动脉远端及基底动脉>颈内动脉颅外段>大脑前动脉>大脑后动脉>颈内动脉虹吸段>椎动脉起始段;(4)DSA所示狭窄程度:207例316条狭窄血管中,重度狭窄或闭塞87条(27.5%);(5)157/164例(95.7%)脑卒中病灶与血管狭窄的部位相对应。结论缺血性卒中患者以颅内血管狭窄为多见,大脑中动脉主干狭窄的发生率最高,其次是椎动脉远端及基底动脉。
Objective To analyze distribution of intracranial and extracranial arteriostenosis in patients with ischemic stroke. Methods 306 patients with ischemic stroke were collected during January 2002 to March 2005. All patients underwent color ultrasonography of carotid, TCD, MRA and DSA, According to NASCET, arteriostenosis was grouped into five grades： normal artery, mild stenosis（29% ）, moderate stenosis （30%--69% ）, severe stenosis（70%---90% ） and occlusion（ 100% ）. Results （ 1 ） As for incidence of intracranial and extracranial arteriostenosis, 149 were of intracranial stenosis, 25 extracranial stenosis and 33 both. （2） As for incidence of single or dual stenosis, among 207 with arteriostenosis, single stenosis amounted to 129 and dual to 78. （3） Stenosis occurred in middle cerebral artery, distal vertebral artery, basilar artery, extracranial part of internal carotid artery, anterior cerebral artery, posterior cerebral artery, siphon part of internal carotid artery and onset part of vertebral artery in an order of decreased frequency. （4） DSA analysis revealed that, among 316 narrow blood vessels of 207 patients, 87 vessels were shown as severe stenosis or obstruction, accounting for 27.5%. （5） Among 164 cases, infarction occured in the corresponding stenostic vessel in 157 patients, accounting for 95.7%. Conclusions Intracranial arteriostenosis is the most frequently encountered in those with ischemic stroke. Thereto, frequency of stenosis in middle cerebral artery is the highest, distal vertebral artery and basilar artery are next.
