Abstract：Objective To explore the methods to treat posterior inferior cerebellar artery (PICA) aneurysms and their effects. Methods The clinical data of 21 patients with PICA aneurysms, of whom, 7 were treated by surgery, 13 by the endovascular embolization and 1 by conservative treatment from January, 2008 to December, 2013, were analyzed retrospectively. Results Five patients receiving the endovascular treatment died within 7 days after the embolization. Sixteen patients were followed up from 6 to 36 months. One patient receiving coils embolization was treated by stent-assisted coils embolization because the aneurysm recurred 1 year after the coils embolization. One patient undergoing the surgery still had ataxia during the following up. The aneurysm was unchanged 2 years after the conservative treatment in 1 patient. There were no recurrence of the aneurysms and complications in the other 13 patients during the following up. Conclusions The patency of the medullar branch of PICA is a prerequisite for treatment of PICA aneurysms. The method to treat PICA aneurysms should be selected according to the aneurysms and whether PICA is a superior blood vessel or not. The effects of the endovascular embolization and surgery on PICA aneurysms are good if the method to treat them is proper for PICA aneurysms.
