Abstract：
UNASSIGNED: Microsurgical treatment of paraclinoid aneurysms is a complex task that generally requires anterior clinoid process (ACP) removal to obtain adequate surgical exposure. This procedure poses a considerable technical difficulty due to the association of the ACP to critical neurovascular structures. Furthermore, anatomical variations in the parasellar region, such as the caroticoclinoid foramen (CCF) or an interclinoid bridge (ICB), may impose additional challenges and increase surgical complications. The present study aims to briefly review some anatomic variations in the parasellar region and describe a step-by-step surgical technique for a hybrid anterior clinoidectomy based on the senior author\'s experience.
UNASSIGNED: We present two cases with bone variations on the parasellar region in patients with a paraclinoid aneurysm and another with a posterior communicating segment aneurysm treated by microsurgical clipping at our hospital.
UNASSIGNED: We focused on safely dealing with these variations during surgery, without further complications, and with good postoperative results. Patients were discharged with no significant deficit. Postoperative control, computed tomography angiography showed complete exclusion of aneurysms.
UNASSIGNED: Although anatomical variations in the parasellar region can complicate surgical clipping of these aneurysms, it is essential to ensure the best possible surgical outcome to conduct thorough preoperative and radiological evaluations.

摘要：
■显微手术治疗突突旁动脉瘤是一项复杂的任务，通常需要去除前斜突（ACP）以获得足够的手术暴露。由于ACP与关键的神经血管结构相关联，因此该程序存在相当大的技术难度。此外，鞍旁区域的解剖学变异，如类胡萝卜素孔（CCF）或类间桥（ICB），可能会带来额外的挑战并增加手术并发症。本研究旨在简要回顾鞍旁区域的一些解剖变异，并根据资深作者的经验描述一种用于混合前路临床切除术的分步手术技术。
■我们介绍了在我们医院接受显微外科手术夹闭治疗的2例，其中2例患者的鞍旁区域骨变异，另一例患者的后交通段动脉瘤。
■我们专注于在手术过程中安全处理这些变化，没有进一步的并发症，术后效果良好。患者出院，无明显赤字。术后控制,计算机断层扫描血管造影显示动脉瘤完全排除.
■尽管鞍旁区域的解剖变异会使这些动脉瘤的手术夹闭复杂化，必须确保尽可能好的手术结果,以进行彻底的术前和放射学评估.
