术中超声引导置入定位针在脑海绵状血管畸形切除术中的应用

Application of located needles guided by intraoperative ultrasound in resection of brain cavernous malformations

目的 探讨术中超声引导下放置定位针在脑海绵状血管畸形切除术中的应用价值.方法 对术前MRI和（或）CT诊断为脑海绵状血管畸形的14例患者14处病变在术中超声引导下置入定位针定位后进行手术切除.结果 14处脑海绵状血管畸形均在术中超声引导下放置定位针精确定位,手术顺利完整切除.病变距离脑皮层表面1.5～2.9 cm,病变大小0.8～2.8 cm.14处病灶彩色多普勒超声显示内部可见少许点状血流.结论 术中超声引导置入定位针能够准确定位切除脑海绵状血管畸形.

Objective To explore the value of the located needles guided by intraoperative ultrasound in resection of brain cavernous malformations. Methods Fourteen patients diagnosed as brain cavernous malformations confirmed by preoperative CT and MRI. Detected by the located needles under intraoperative ultrasound guidance, 14 lesions were excised. Results Intraoperative ultrasound-guided needles accurately located 14 cases of patients with brain cavernous malformations. Fourteen lesions were removed successfully. The distances between lesions and the dura mater were 1.5-2.9 cm,the sizes of lesions were 0.8-2.8 cm. Fourteen lesions by color Doppler flow imaging showed point-like blood flow. Conclusions Brain cavernous malformations can be accurately detected by the located needles under intraoperative ultrasound guidance.
