辅助技术在颅内动静脉畸形手术中的应用

目的 探讨B超、神经导航以及吲哚菁绿血管造影在颅内动静脉畸形手术中的应用价值.方法 回顾性分析2009年1至10月北京天坛医院神经外科脑血管病区收治的43例颅内动静脉畸形患者临床资料.其中男26例,女17例;年龄8～53岁,平均26.51岁.所有患者在手术中分别或联合采用B超、神经导航或吲哚菁绿血管造影辅助病灶切除,且术后全部病例行脑血管造影(DSA)或CTA检查,同时记录术后新发并发症及恢复情况.结果 所有患者均全切病灶,术中辅助技术检测结果均与术后DSA或CTA吻合.术后新发神经功能障碍3例(7.0%),其中2例出现双侧视野同向性偏盲,另1例为复视.43例患者KPS(Karnofsky Performance Scale)评分均高于80分.结论 采用B超、神经导航或吲哚菁绿血管造影技术辅助颅内动静脉畸形手术切除,均有助于鉴别血管性质和反映病灶边界.但其侧重各有不同.因此,该3种辅助技术有选择的联合应用可以使术者增加术中判断的准确性,从而收到最佳手术效果.

Strategy for assisted cerebral arteriovenons malformation surgery

Objective To evaluate the surgical effects of such adjuvant techniques as type B ultrasound, neuronavigation and intraoperative indocyanine green vedioangiography (ICGA) on intracranial arteriovenous malformation ( AVM) surgery. Methods From January to October 2009, 43 AVM patients treated at our center were retrospectively studied, including 26 males and 17 females with an age range of 8 to S3 years old (mean; 26. 51). Type B ultrasound, neuronavigation or ICCA were employed during surgical procedures in all cases. Intraoperative findings were compared with those of postoperative digital subtraction angiography ( DSA) or computed tomography angiography (CTA) . And the clinical outcomes were evaluated. Results As confirmed by postoperative DSA or CTA, the lesions of all 43 patients were totally removed. Only 3 patients (7.0%) suffered from new neurological deficits, including homonymous hemianopia in 2 patients and diplopia in 1. And the Karnofsky performance scale was higher than 80 for each patient. Conclusion The feeding arteries and draining veins can be differentiated by intraoperative type B ultrasound, neuronavigation and ICGA. All three adjuvant techniques can define the lesion boundary. However, each of them has its own benefits and drawbacks. It indicates that the combination of two or more techniques may help to improve the quality and outcome of surgical procedures.
