Contralateral approach to giant ruptured and unruptured ophthalmic artery aneurysms: patient series.

Background: Giant ophthalmic artery (OphA) aneurysms remain surgically challenging despite the progress in endovascular treatments. This study describes the contralateral interoptic corridor in select patients based on imaging criteria suitable for clipping. The aim of this study was to show that despite the growing use of novel endovascular techniques, such as coil embolization and flow diversion, for the treatment of OphA aneurysms, microsurgical clipping may still be preferred for giant ones under certain conditions.
