目的 探讨经幕下小脑上入路(Krause入路)显微外科切除松果体区肿瘤的方法和治疗效果。方法 分析1998年3月至2002年4月收治的松果体区肿瘤8例,其中生殖细胞瘤4例,胶质瘤2例,松果体瘤和松果体囊肿各1例。所有病人均采用坐位、气管内插管全麻、经Krause入路显微肿瘤切除,其中2例术中辅助影像导航定位。结果 除1例胶质瘤与大脑大静脉粘连,残存少许肿瘤外,其余病例均达解剖切除,脑脊液循环通畅,无后遗症状。结论 坐位Krause入路显示三脑室后部病变解剖结构清晰,病变暴露良好,基本能达到病灶全切。
Objective To investigate the method and the therapeutic effect of microsurgical removal of tumors in the pineal region through supratentorial cerebellar approach (Krause approach). Methods Eight cases of pineal region tumors were treated from March 1998 to April 2002, including 4 germ cell tumors, 2 glioma, 1 pineal tumor and 1 pineal cyst. All patients were sitting, endotracheal intubation general anesthesia, microscopic tumor resection by Krause approach, of which 2 cases assisted imaging navigation positioning. Results In addition to a case of glioma and cerebral vein adhesions, leaving a small number of tumors, the rest of the cases reached anatomic resection, cerebrospinal fluid circulation, no symptoms. Conclusion The sitting Krause approach shows that the anatomical structure of the posterior part of the third ventricle is clear, the lesions are well exposed and the lesions can be cut completely.
