应用ellman射频电波刀治疗颅内海绵状血管瘤

Treatment of intracranial cavernous hemangiomas by ellman radiosurgery knife

目的 总结颅内海绵状血管瘤的临床特点和应用ellman射频电波刀治疗的体会。方法 回顾与分析我们自 2 0 0 1年 6月～ 2 0 0 3年 5月共 2年间手术治疗的 2 1例颅内海绵状血管瘤 ,在显微镜下 ,采用ellman射频电波刀进行血管肿瘤切除。结果 根据头颅CT、MRI及手术所见将 2 1例患者分为 2种类型 ,Ⅰ型 :19例 ,病变位于脑内 ,均获得镜下全切除 ,术后症状获得不同程度改善 ;Ⅱ型 :2例 ,病变位于脑外 ,获得镜下大部分切除 ( 1例术前给予放射治疗 )。结论 正确诊断颅内海绵状血管瘤。

Objective To summarize the clinical diagnosis and treatment of intracranial cavernous hemangiomas by ellman radiosurgery knife in order to improve the clinical outcome.Methods Twenty-one patients with intracranial cavernous hemangiomas treated microsurgically by ellman radiosurgery knife from June 2001 to May 2003 in Xijing hospital and 211st hospital were analyzed retrospectively.Results The clinical manifestations of the patients included headaches,hemorrhage,epilepsy and dysfunction of cranial nerve.The 21 patients with intracranial cavernous hemangiomas could be classified into two types mainly based on the imaging findings(CT or MRI scan) or intraoperative findings.Type I hemangiomas located in the brains in 19 cases were totally removed under a microscope,and the postoperative signs were improved to varying degrees.Type II hemangiomas out of the brain were partially removed by using the microneurosurgical techniques (one case received radiotherapy before operation).Conclusion The correct diagnosis and proper operative methods for intracranial cavernous hemangiomas are the bases for the patients to achieve good recovery.
