本文对６６例脑血管畸形的临床影像、ＴＣＤ进行了对比分析；并以１６６名健康人各年龄组ＴＣＤ各指标值进行对照；另将其中３０例经Ｘ刀立体定向放射治疗的结果，进行了为期２个月到３年的随诊观察，并结合治疗前、后临床、ＴＣＤ、ＤＳＡ、ＭＲＡ对比分析。所用ＴＣＤ仪为ＥＭＥＴＣ２０２０型，定向立体Ｘ刀放射治疗仪为菲利浦ＳＲＳ２００型。选择病例均以多次人工栓塞术后无效者，畸形血管因直径大小以４ｃｍ以下者为主体，最大者可达８ｃｍ×４ｃｍ×３ｃｍ。６６例中男４０例、女２６例，年龄＜２０岁１６例，２１～４０岁３８例、４１～６０岁以上１２例。病种分类：动静脉畸形（ＡＶＭ）者５９例，海绵状血管瘤２例，Ｍｏｙａｍｏｙａ氏病５例。部位分布：幕上５５例，幕下６例、脑底５例。各脑叶分布：额１８例、颞１５例、顶１９例、枕１０例、基底节、丘脑６例、小脑５例、胼胝体１例、中脑、脑室１例、脑底环５例。按血动脉分布：基底动脉系统１０例、颈动脉系统５６例，其中以ＭＣＡ、ＡＣＡ为主要病变动脉。按ＡＶＭ血管团直径大小分类：＜２ｃｍ，２３例、２．１～４ｃｍ，３４例、＞４．１ｃｍ者，４例、脑底动脉网５例。影像诊断：ＣＴ脑扫描２３例、ＭＲ２９例、ＭＲＡ７例、ＤＳＡ?
In this paper, 66 cases of cerebrovascular malformations of clinical imaging, TCD were analyzed comparatively; 166 cases of healthy people in each age group TCD control values; the other 30 cases by X-knife stereotactic radiotherapy results were A 2-month to 3-year follow-up observation was performed and combined with clinical, TCD, DSA and MRA before and after treatment. TCD instrument used for the EMETC2020 type, directional X-knife radiotherapy apparatus Philips SRS200 type. Selected cases were repeated after artificial embolization ineffective, abnormal blood vessels due to the diameter of less than 4cm as the main body, the largest up to 8cm × 4cm × 3cm. 66 cases of 40 males and 26 females, age <20 years in 16 cases, 21 to 40 years in 38 cases, 41 to 60 years old in 12 cases. Disease classification: arteriovenous malformations (AVM) in 59 cases, cavernous hemangioma in 2 cases, 5 cases of Moyamoya’s disease. Location distribution: 55 cases on the screen, 6 cases under the screen, brain in 5 cases. There were 18 cases in each brain, 15 cases in temporal, 19 cases in top, 10 cases in occipital, 6 cases in basal ganglia, 6 cases in thalamus, 5 cases in cerebellum, 1 case in corpus callosum, 1 case in midbrain and brain and 5 cases in brain base. By blood artery distribution: basilar artery system in 10 cases, carotid system in 56 cases, of which MCA, ACA as the main lesion artery. According to the size of the AVM vascular diameter: <2cm, 23 cases, 2.1 ~ 4cm, 34 cases,> 4.1cm, 4 cases, cerebral artery network in 5 cases. Imaging diagnosis: CT brain scan in 23 cases, MR29 cases, MRA in 7 cases, DSA?
