We describe a novel extracranial (EC)-to-intracranial (IC) bypass technique between the occipital artery and upper posterior circulation (UPC) for revascularization of the posterior circulation through the presigmoid approach. Five formalin-fixed human heads were examined to demonstrate the detailed anatomy of the occipital artery and UPC and illustrate the step-by-step bypass procedure. The occipital artery, a branch of the external carotid artery, can be anastomosed to the P2/P3 segment of the posterior cerebral artery and S1/S2 segments of the superior cerebellar artery as an alternative to EC bypass donor segments for treatment of affection requiring revascularization. Presigmoid approach for the anastomosis of the occipital artery to the UPC provides a shorter distance, due to resection of some bones.
我们描述了一种通过乙状窦前入路，在枕动脉与上后循环（UPC）之间建立的新型颅外（EC）-颅内（IC）搭桥技术，用于后循环血管重建。对5个福尔马林固定的人头进行了检查，以展示枕动脉和UPC的详细解剖结构，并说明逐步搭桥手术过程。枕动脉是颈外动脉的一个分支，可与大脑后动脉的P2/P3段和小脑上动脉的S1/S2段进行吻合，作为EC搭桥供体段的替代方案，用于治疗需要血管重建的疾病。由于切除了部分骨头，通过乙状窦前入路将枕动脉与UPC进行吻合可提供更短的距离。
