OBJECTIVE To discuss the surgical strategies and analyze the clinical outcomes of multiple intracranial aneurysms (MIA). METHODS The clinical data of 49 MIA patients surgically treated between January 2009 and December 2013 was analyzed retrospectively. Among the 49 patients, 12 patients were male and 37 were female, mean age (49 ± 11) years. Thirty-five patients had ruptured aneurysms, and 14 had unruptured aneurysms. Treatment strategies included one-stage operation (MIA were treated in one-stage with an unilateral approach), two-stage treatment (MIA were treated stage by stage) and partial treatment (only ruptured aneurysm was treated). Postoperative CT angiograms (CTA) or digital subtraction angiograms (DSA) were reviewed and the Glasgow Outcome Scale (GOS) scores were evaluated during follow-up period. RESULTS Thirty-two patients (65.3%) underwent one-stage operation, 9 patients (18.4%) underwent two-stage treatment, and 8 patients (16.3%) underwent partial treatment. Forty-seven patients were followed up 4-49 months, mean (22 ± 7) months. Postoperative CTA or DSA showed no aneurysm recurrence. According to the GOS scores, 41 patients (83.7%) with good outcomes (GOS 4, 5), 6 patients (12.2%) were disabled (GOS 2, 3) and 2 patients (4.1%) were dead (GOS 1). CONCLUSIONS Selecting the right patients for surgery and making personalized surgical strategies based on the characteristics of patients and aneurysms could improve the surgical outcomes of MIA.
