There are two main types of approaches for anterior communicating artery (AcomA) aneurysms, namely pterional approach, and an interhemispheric (IH) approach. Pterional approach is the most common for anterior circulation aneurysms. However, this approach cannot be used without resection of gyrus rectus when aneurysm is located high within the IH fissure and directed posterosuperiorly, which is better handled with IH approach. In this article, we will describe the tricks of IH approach with a case illustration.
前交通动脉（AcomA）动脉瘤主要有两种手术入路，即翼点入路和经纵裂（IH）入路。翼点入路是前循环动脉瘤最常用的入路。然而，当动脉瘤位于纵裂内较高位置且指向后上方时，不切除直回就无法采用该入路，而经纵裂入路对此类情况处理更佳。在本文中，我们将通过一个病例说明来介绍经纵裂入路的技巧。
