Localization in the Interpeduncular Cistern as Risk Factors for the Thalamoperforators' Ischemia, Poor Outcome, and Oculomotor Nerve Palsy in Patients with Complex Unruptured Basilar Apex Aneurysm Treated with Neck Clipping

Objective We aimed to evaluate the relationship between aneurysm morphology, thalamoperforators' ischemia, outcome, and oculomotor nerve palsy (ONP) that continued during the follow-up period in 23 patients with complex unruptured basilar apex aneurysms (BAAs) treated with clipping. Methods Ane...

Zusammenfassung:	Objective We aimed to evaluate the relationship between aneurysm morphology, thalamoperforators' ischemia, outcome, and oculomotor nerve palsy (ONP) that continued during the follow-up period in 23 patients with complex unruptured basilar apex aneurysms (BAAs) treated with clipping. Methods Aneurysm morphology included the size, distance of neck from the posterior clinoid process, dome projection, and localization in the interpeduncular cistern (LIC). BAAs with neck >4 mm, posterior projection, retro/subsellar, and dome-to-neck ratios
