METHODS: The authors retrospectively reviewed the records of the microsurgical treatment of unruptured and ruptured giant OphA aneurysms at the University Hospital Center \"Mother Teresa,\" Tirana, from 2007 to 2016. Four patients were selected for microsurgery and the contralateral approach using ophthalmic evaluations and coronal imaging on computed tomography, magnetic resonance imaging, and digital subtraction angiography that demonstrated aneurysms with a small neck and an orientation between 11 and 13 on the coronal clock face. A prefixed chiasm was a contraindication to this approach.
CONCLUSIONS: Giant OphA aneurysms can be safely clipped through a contralateral interoptic corridor without creating new visual deficits or a residual aneurysm. https://thejns.org/doi/10.3171/CASE2473.
方法:作者回顾性回顾了大学医院中心“特蕾莎修女,\"地拉那,从2007年到2016年。选择四名患者进行显微外科手术和对侧入路,使用眼科评估和计算机断层扫描的冠状成像,磁共振成像,和数字减影血管造影显示动脉瘤的颈部较小,在冠状时钟面上的方向在11和13之间。前缀交叉是这种方法的禁忌症。
结论:巨大的OphA动脉瘤可以通过对侧视间通道安全地夹住,而不会产生新的视觉缺陷或残留动脉瘤。https://thejns.org/doi/10.3171/CASE2473.
