Propensity Score-Matched Analysis of Endovascular Treatment and Microsurgery for Unruptured Middle Cerebral Artery Aneurysms: Long-Term Outcomes over 6-Year Follow-Up.

ABSTRACT: Objectives: The choice between endovascular treatment and microsurgery for unruptured intracranial aneurysm (UIA) is influenced by aneurysm location, with middle cerebral artery (MCA) UIAs traditionally requiring surgery. This study compares these treatment modalities using propensity score matching (PSM). Methods: This single-center analysis included adults with saccular MCA UIAs who underwent treatment. PSM incorporated patient and aneurysm characteristics to create comparable groups. Results: Before matching, 124 patients underwent microsurgery and 28 underwent endovascular treatment. With a median follow-up of 76.5 months, 93.4% achieved good functional outcome (modified Rankin Scale [mRS] 0-2), including 117 (93.4%) in the surgical group and 25 (89.3%) in the endo
