术中超声导航在脑海绵状血管瘤切除术中的应用

目的探讨术中超声导航在脑海绵状血管瘤切除术中的应用价值。方法对2006年3月～2011年12月成都大学附属医院17例神经外科显微手术中采用实时超声影像引导病灶定位，指导手术路径选择，并动态了解病变位置的变化情况及手术切除程度。结果本组所有病灶均在显微镜下完整切除，无死亡病例，术后患者一般状况良好。术后所有病灶均经病理证实为海绵状血管瘤，术前MRI诊断与病理符合率达100％。术后随访3～24个月（平均约11．3个月），除1例患者因术后2个月再次出血抢救无效死亡外，其余患者临床症状均不同程度改善，未出现再次出血、偏瘫等并发症。结论术中超声导航操作简便，定位准确，能够实现实时影像导航；与显微神经外科配合能够有效地起到降低手术副损伤，提高手术精度的作用。

The value of intraoperative ultrasound examination in rescetion of intracranial cavernous hemangioma

Objective To explore the value of intraoperative ultrasound examination in rescetion of intracranial eavernous hemangioma. Methods From March 2006 to December 2011, 17 cases of microsurgery neurosurgery in the Affiliated Hospital of Chengdu University were used to real-time ultrasound images to guide lesion localization and to guide surgical path selection, the change in circumstances and the extent of surgical resection of the lesion location were dynamicly understand. Results All lesions in this group were under the microscope complete resection, no deaths, the patients were generally in good condition after surgery. After surgery, all lesions were pathologically confirmed cavernous hemangioma, preoperative MRI diagnosis and pathology in line with the rate of 100%. The patients were followed up for 3 to 24 months （average 11.3 months）, in addition to one patient was died because of bleeding again after 2 months, the rest of the clinical symptoms were improved in different degrees,and there was no bleeding, hemiplegia and so on. Conclusion Intraoperative uhrasound navigation is very simple and accurate to achieve realtime image guidance. It is able to reduce surgical vice injury and improve surgical accuracy.
