摘　　要：BACKGROUND Subarachnoid hemorrhage is a severe neurological condition that requires prompt and appropriate treatment to prevent complications.Aneurysms are the most common cause of spontaneous subarachnoid hemorrhage.Conversely,basilar artery perforator aneurysms(BAPAs)are a rare etiology.There is no consensus on the optimal management of ruptured BAPAs in the acute setting.CASE SUMMARY We present a case series of 3 patients with ruptured BAPAs who were treated at our institution.Two patients had a modified Fisher grade of I,and one had a grade of IV on initial presentation.The aneurysms were detected by computed tomography angiography in two cases and conventional angiography in one case.The 3 patients underwent endovascular treatment with Guglielmi detachable coils.Post-treatment,the patients had good clinical outcomes,and follow-up brain computed tomography scans showed reduced subarachnoid hemorrhage without any new hemorrhage.However,one patient experienced a cerebral infarction 2 months later and eventually succumbed to the condition.The other 2 patients showed progressive recovery,and no aneurysm recurrence was observed at the 2-year follow-up.CONCLUSION Endovascular treatment may be a preferable approach for managing ruptured BAPAs compared with surgical intervention or conservative management.Early detection and prompt treatment is important to achieve favorable patient outcomes.
