Nine cases of arteriovenous malformations of the posterior fossa were operated upon, using microsurgical techniques. The excision was radical in eight patients. Seven of them, as well as the sole patient who had a partial removal of the malformation, returned to their previous occupations without neurological signs. In one case the preoperative deficit was unchanged. Some lesions that appear to penetrate the brain stem actually lie on its surface and can be dissected through an extrapial plane of cleavage. Extension of the malformation into the cerebellar peduncles requires dissection of the tangle and opening of the IVth ventricle.
对9例后颅窝动静脉畸形患者采用显微外科技术进行了手术。8例患者的病变被彻底切除。其中7例以及仅接受了畸形部分切除的1例患者恢复了之前的工作，且无神经功能体征。有1例患者术前的神经功能缺损没有变化。一些看似穿透脑干的病变实际上位于脑干表面，可以通过软膜外分离平面进行解剖。畸形延伸至小脑脚时，需要对血管团进行解剖并打开第四脑室。
