神经导航下切除海绵状血管瘤

Neuronavigation for the resection of intracranial cavernous angiomas

目的介绍ＳｔｅａｌｔｈＳｔａｔｉｏｎ神经导航系统在颅内海绵状血管瘤手术中的应用。方法在６例以癫痫起病的海绵状血管瘤手术中，ＳｔｅａｌｔｈＳｔａｔｉｏｎ神经导航系统提供手术野和ＣＴ影像的实时吻合、术中导航，其中４例锁眼外科手术，２例皮瓣开颅手术。结果６例手术均导航定位全切病灶及其周边含铁血黄素沉着带、胶质增生和钙化，无手术并发症，术后癫痫消失。平均注册误差１６５～４５３ｍｍ，每１０ｃｍ预期准确性１８２～３２８ｍｍ，持续准确性为０５０～３４５ｍｍ。结论在海绵状血管瘤手术中，应用ＳｔｅａｌｔｈＳｔａｔｉｏｎ系统导航，准确性高，可靠性强。

Objective To evaluate the use of the Stealth Station neuronavigator in conjunction with preoperative computerized tomography (CT) in the resection of intracranial cavernous angiomas(CAs).WT5HZMethods The Stealth Station neuronavigator was used to provide realtime correlation of the operating field and computerized images in 6 patients with CAs. All of them suffered from epileptic seizures.T5HZResults Neuronavigationguided lesionectomy with removal of hemosiderin deposition, gliosis and calsification in all cases was performed precisely. Mean fiducial error,predicted accuracy at 10 cm, and sustained accuracy ranged from 165 to 453 mm, 182 to 328 mm, and 050 to 345 mm, respectively. Conclusions The Stealth Station neuronavigator is reliable and accurate in the resection of CAs.
