Is clipping better than coiling in the treatment of patients with oculomotor nerve palsies induced by posterior communicating artery aneurysms? A systematic review and meta-analysis

Posterior communicating artery aneurysms (PcomAAs) are the second most common aneurysms, accounting for 25% of all intracranial aneurysms [1]. It has been estimated that oculomotor nerve palsy (ONP) occurs in up to one-third of patients with posterior communicating artery (PcomA) aneurysms due to a mass effect on the oculomotor nerve [2]. Compression of the oculomotor nerve resulting in ONP is a common initial symptom and in some cases the only neurological deficit in patients with PcomAAs [3 –6].
