<b>Objective</b>To investigate the safety and efficacy of endovascular embolization for ruptured posterior inferior cerebellar artery （PICA） aneurysms. <b>Methods</b>The clinical data of 18 patients with ruptured PICA aneurysms admitted in Nanjing First Hospital from June 2014 to August 2021 were retrospectively analyzed. <b>Results</b>Immediate postoperative angiography showed that 14 patients （77.78%） had Raymond grade Ⅰ dense embolism, 2 patients （11.11%） had Raymond grade Ⅱ residual tumor neck, and 2 patients （11.11%） had Raymond grade Ⅲ residual tumor. Perioperative complications occurred in 2 cases （11.11%）, and cerebral stem and cerebellar infarction resulted in death in 1 case （5.56%）. One patient （5.56%） with ruptured aneurysm ruptured again during the operation. Except for 1 died patient, the mRS scores of 17 patients were all ≤3 points, and the good prognosis rate was 94.44% （17/18）. Seventeen patients were followed up for 6-12 months after operation, 2 patients with PICA tumor neck recurrence after simple coil embolization, the recurrence rate was 11.11% （2/18）, one of them was cured by LVIS double stent treatment. <b>Conclusion</b>Endovascular embolization is a safe and effective method for the treatment of PICA aneurysms. The design of treatment strategy should be based on the location and morphological characteristics of the aneurysm and parent artery.
