脳底動脈先端部動脈瘤手術の工夫 : Pterional approachでの諸問題とその対策  [in Japanese] Technical Refinements for Surgery of Basilar Top Aneurysm : Surgical Complications and Their Preventions during Pterional Approach  [in Japanese]

We provide intraoperative problems and their preventive measures during the pterional approach to the basilar top aneurysm. We focus on the surgical techniques to obtain a wider operative field through the pterional approach. The surgical difficulties depend on various factors, including the size, location, and direction of the basilar top aneurysm. In particular, the interrelationship between the location of the internal carotid artery and the basilar top aneurysm is an important factor to be fully assessed preoperatively.
