The surgical treatment of aneurysms that arise at the origin of the pericallosal artery is technically difficult. This report describes a technique that improves the exposure of the proximal vasculature during a craniotomy for pericallosal aneurysms. A portion of the corpus callosum was resected in two patients before the manipulation of their aneurysms. The resection provided excellent exposure of the A2 segment of the anterior cerebral artery, and both aneurysms were clipped safely. Neither patient exhibited signs of hemispheric disconnection. The authors conclude that partial callosal resection improves access to the proximal vessels during procedures for pericallosal aneurysms.
起源于胼周动脉起始部的动脉瘤的外科治疗在技术上具有挑战性。本报告描述了一种在开颅手术治疗胼周动脉瘤时改善近端血管显露的技术。在两名患者处理动脉瘤之前切除了部分胼胝体。该切除提供了大脑前动脉A2段的极佳显露，并且两个动脉瘤均被安全夹闭。两名患者均未出现半球分离的体征。作者得出结论，部分胼胝体切除可改善在处理胼周动脉瘤过程中对近端血管的显露。
