经小脑上天幕下外侧入路切除脑桥中脑海绵状血管畸形

　　经小脑上天幕下外侧入路切除脑桥中脑海绵状血管畸形(Lateral supracerebellar infratentorial approach for pontomesencephalic cavernous malformations)

　　Cavernomas at the posterolateral pontomesencephalic surface can be approached from a lateral infratentorial supracerebellar corridor. In this surgical video, we demonstrate two cases of brainstem cavernomas resected through a lateral supracerebellar infratentorial approach. A supine position with lateral turn of the head was used along with significant reverse Trendelenburg to allow the cerebellum to fall away with gravity from the tentorium. After exposure of the posterior surface of the brainstem between the tentorium and the superior cerebellar surface with aid of neuronavigation, the cavernomas were safely resected.

　　经天幕下小脑上外侧入路能达到脑桥中脑后外侧上的海绵状血管瘤。这篇手术视频展示经小脑上天幕下外侧入路切除脑干海绵状血管瘤2例。患者取俯卧位，头转向外侧，使用高度的反向特伦德伦伯格卧位，以便使得小脑在重力下脱离天幕。经过天幕下和小脑上部的入路得到脑干后部的暴露之后，在神经导航辅助下顺利地切除海绵状血管瘤。
