摘要
目的开放式磁共振结合导航系统,可以获得准确的手术定位、对手术器械的实时引导和术中监控。本文探讨磁共振导航应用于无框架立体定向神经外科的初步经验、可能的并发症及应用前景。方法使用Philip公司的0.23T开放式磁共振结合iPath200光学导航系统,对4例脑占位及4例脯脓肿患者分别施行脯活检和脓肿穿刺抽吸术。结果所有患者均获得穿刺针的准确定位。4例脑活检取得足够的组织样本,术后无并发症出现;4例脑脓肿术后影像资料证实脓肿腔体积缩小50%以上,1例小脑脓肿患者死亡,死亡原因为多器官功能衰竭,其余患者神经功能缺损症状均有不同程度的改善,未发生手术所致并发症。结论磁共振导航应用于脑活检和脑内囊性病变的穿刺引流,手术成功率高,对患者损伤小。
Objective The integration of open-MR and optical navigation system can be used in neurosurgery for accurately lesion positioning,real-time tracing of surgical devices and intraoperative monitoring.We evaluate our preliminary clinical experience with this new technique.Methods An open-design 0.23 T magnet combined with iPath 200 optical navigation system was used for the 8 frameless MR-guided neurosurgical procedures(4 brain biopsys and 4 drainage of brain abscess).Results In all cases the technique resulted in successful placements of the needles within the target lesions to complete the procedures.Post-procedure MR scan displayed the volumes of 4 abscesses reduced by more than 50%.One of the patients suffered from cerebellar abscess died of multiple organs failure.The clinical manifestations in the other three patients improved evidently without complications induced by procedures,conclusion The MR-guided procedures with high success rate may cause minimal invasive injuries without serious complications.
