Abstract：Objective The advantages of clipping the distal posterior inferior cerebellar artery aneurysms via cerebellomedullary fissure approach and the microsurgical skills are discussed.Methods A total of 23 cases of the distal posterior inferior cerebellar artery aneurysms were clipped through cerebellomedullary fissure under the microscope.Results Among 23 cases with 33 aneurysms, 31 were totally clipped and 2 were removed, with a clipping rate of 94.9%.No operative mortality occurred.Conclusion Clipping through cerebellomedullary fissure approach can remove the hemotoma of the fourth ventricle hematoma, reduce the intracranial pressure, protect cerebellum from damage, reduce the extract of the vessels and nervous tissues to a minimum extent and the rupture of aneurysms, so the safety of surgery is improved.
