摘要
目的探讨经颅彩色多普勒超声(TCCS)及经颅超声造影(CE-TCCS)在颅内动静脉畸形诊断中的应用价值。方法对31例疑为颅内动静脉畸形的患者分别行经颅彩色多普勒超声及经颅超声造影检查,比较造影前后畸形血管团及供血动脉的显示率,并与数字减影血管造影(DSA)或计算机体层摄影血管成像(CTA)检查结果进行对比。结果 (1)经CTA或DSA证实30例为颅内动静脉畸形,1例为颅内海绵状血管瘤。(2)经颅彩色多普勒超声对颅内动静脉畸形的显示率为70%(21/30),经颅超声造影对颅内动静脉畸形的显示率为96.7%(29/30)。对位于颞叶(11例)、岛叶(1例)、小脑(1例)的颅内动静脉畸形经颅彩色多普勒超声测量动静脉畸形血管团大小与DSA测量结果一致,而5例位于额叶、1例位于顶叶及1例位于枕叶的动静脉畸形血管团测值(2.4cm×3.0cm)明显小于DSA测值(3.0cm×3.6cm)。经颅超声造影测量畸形血管团的大小均与DSA测值一致(3.5cm×4.4cm)。(3)经颅彩色多普勒超声对供血动脉的显示率为59.5%(22/37),经颅超声造影对供血动脉的显示率为83.7%(31/37),造影后供血动脉流速较造影前略增快,但造影前后收缩期峰值流速(PSV)、舒张末期流速(EDV)及阻力指数(RI)测值比较差异无统计学意义(P〉0.05)。结论经颅超声造影可提高颅内动静脉畸形及供血动脉的显示率,经颅超声造影测量畸形血管团大小与DSA检查结果更为一致。
Objective To explore the value of transcranial color-coded sonography(TCCS)and contrast-enhanced transcranial color-coded sonography(CE-TCCS) in intracranial arteriovenous malformations. Methods Thirty-one patients who were firstly diagnosed with intracranial arteriovenous malformations were imaged using transcranial color-coded sonography and contrast-enhanced transcranial color-coded sonography respectively. The display rate of arteriovenous malformations and feeding artery were compared before and after injected sonovue. Results There were 30 arteriovenous malformations and 1 hemangioma with the examination of CTA or DSA. The display rate of arteriovenous malformations by TCCS and CE-TCCS were 70% and 96.7%, respectively. For arteriovenous malformations which were located at temporal lobe, insular and cerebellar,the sizes measured by TCCS were consistent with those of DSA. But for frontal lobe(5 cases),parietal lobe(1 case)and occipital lobe(1 case),the sizes which measured by TCCS were significantly smaller than DSA. The sizes of arteriovenous malformations measured by CE-TCCS were consistent with those of DSA regardless of locations. The display rates of feeding arterys by TCCS and CE-TCCS were 59.5% and 83.7%, respectively. The flow velocity of feeding artery measured by CE-TCCS was much faster than TCCS. But there was no significant difference among them in PSV, EDV and RI. Conclusions The contrast-enhanced transcranial color-coded sonography can increase the display rate of intracranial arteriovenous malformations, and the size of arteriovenous malformations measured by CE-TCCS was consistent with those DSA.
