BACKGROUND Clipping continues to be one of the treatment strategies for ophthalmic artery aneurysms not amenable for stenting or coiling, or when long-term treatment durability is a concern. However, crescent development of endovascular techniques demands minimal invasiveness in the transcranial approaches while ensuring satisfactory results. METHODS We describe an extradural micropterional keyhole approach (eMKA) to the paraclinoid region and highlight the key anatomical elements of this surgical approach. CONCLUSION The eMKA is a minimally invasive approach that provides access to the paraclinoid region using an extradural corridor. Therefore, it is suitable for clipping of ophthalmic artery aneurysms and other paraclinoid aneurysms.

通过硬膜外微翼片锁孔入路对未破裂的眼动脉瘤进行手术夹闭。

背景 夹闭仍然是眼动脉瘤的治疗策略之一，这些动脉瘤不适合支架或卷曲，或者当长期治疗耐久性受到关注时。然而，血管内技术的新月发展要求经颅方法的侵入性最小，同时确保令人满意的结果。方法我们描述了一种到床旁区域的硬膜外微型锁孔入路 (eMKA)，并强调了这种手术入路的关键解剖学要素。结论 eMKA 是一种微创方法，可使用硬膜外通道进入床旁区域。因此，它适用于眼动脉瘤和其他床旁动脉瘤的夹闭。
