Abstract
We retrospectively analyzed long-term follow-up data for 15 patients after treatment for posterior inferior cerebellar artery (PICA) aneurysm, particularly in relation to disability as assessed using the Modified Rankin Scale (MRS) score. Patients had a mean follow-up of 38 months. At follow-up, 53% of patients, those with an MRS score of ⩽3, were able to lead an independent life, despite minor deficits. Patients with larger aneurysms may be more susceptible to lower cranial nerve palsies.
