Assessment cerebral blood flow infusion by measurement of lenticulostriate artery in neonates by Doppler ultrasound 新生儿豆纹动脉多普勒检测评价脑血流灌注
Objective To study lenticulostriate artery flow of neonatal hydrocephalus caused by suffocation. 目的探讨和研究彩色多普勒超声诊断新生儿窒息后引发脑水肿时大脑终末动脉-豆纹动脉的血流灌注情况。
Analysis of elastic element content in the wall of the normal and the atherosclerotic middle cerebral artery and lenticulostriate branch 正常与硬化大脑中动脉及豆纹支弹性成分的定量分析
Conclusion: Measurement of lenticulostriate artery in neonates by Doppler ultrasound is an accurate and feasible diagnostic method, which reflected cerebral blood flow and cerebral blood flow infusion, and it is valuable for observation and treatment of brain damage. 结论:新生儿豆纹动脉血流多普勒检测准确易行,可反映脑血流动力学变化和大脑中央区血流灌注水平,有助于脑损伤的判断与治疗。
A Micro anatomical Study on Lenticulostriate Arteries 豆纹动脉的显微解剖学研究
The elastic structures of the middle cerebral artery ( MCA) and its lenticulostriate branch in cadavers of healthy individuals and those of the patients with cerebral atherosclerosis were observed with light and electron microscopy. 本文用光镜、电镜观察了正常和硬化大脑中动脉及其豆纹支管壁弹性结构的形态。
Conclusions As the terminal artery of the brain, lenticulostriate artery can directly reflect cerebral blood flow perfusion and it is valuable in judging the degree of neonatal hydrocephalus. 结论豆纹动脉作为脑组织中的终末小动脉直接反映脑血流动力学变化和大脑中央区的血流灌注情况,对评价脑水肿的程度和指导临床治疗帮助较大。
Significance of changes in elastic structures of atherosclerotic middle cerebral artery and its lenticulostriate branch 硬化大脑中动脉及豆纹支管壁弹性结构改变及意义
Results Among the complicated aneurisms, 18 were peripheral artery type ( 81.8%), in which 6 patients originated from perforating arteries, 7 from lenticulostriate arteries, 4 from posterior choroidal arteries; 结果伴发的动脉瘤为外周动脉型18例,占81.81%,其中载瘤动脉为穿支动脉者6例,豆纹动脉者7例,后脉络膜动脉4例。
The internal carotid artery upper space could use as operating space in 7 patients because of absence of the lenticulostriate arteries and the perforating artery of A1 and bifurcation of internal carotid artery. 颈内动脉上间隙均见不同程度增大。7例由于A1及分叉部穿通动脉、M1内侧豆纹动脉缺如形成自然手术间隙进行直接操作。
All 24 sides middle cerebral arteries had middle lenticulostriate artery and lateral lenticulostriate artery. 24侧大脑中动脉均有中间豆纹动脉以及外侧豆纹动脉。
11 sides 'middle cerebral arteries had medial lenticulostriate artery, short course and overlapped with another perforating arteries when entering the anterior perforated substance. 4 sides medial lenticulostriate artery coincided with perforating arteries in A1. 11侧大脑中动脉存在内侧豆纹动脉,行程短,进入前穿质时与其他穿通动脉存在重叠,4侧内侧豆纹动脉与A1段穿通动脉间存在吻合现象。
