A lack of published surgical experience and higher symptomatic recurrence than previously recognized prompted the authors to present their experience with the surgical treatment of unruptured intracranial dissecting aneurysms (uiDas). Hospital records, neuroimaging studies, operative reports, and follow-up records were retrospectively reviewed. all patients underwent surgical exploration of the lesion with proximal clipping of the parent artery through a far-lateral suboccipital craniotomy with or without partial condylar resection. The surgical treatment of vertebral artery-posterior inferior cerebellar artery uiDas has acceptable risk regarding perioperative mortality and morbidity. The incidence of aneurysmal recurrence or the need for retreatment seems to be less than that associated with anticoagulation/antiplatelet therapy or endovascular treatment.
