OBJECTIVE Vertebral aneurysms (VAN) have almost fusiform and irregular formation. Many cases cause by arterial dissection. It is difficult to preserve vertebral arterys (VA) without neck bridging stents. Previous era of stents, we performed endovascular parent artery occlusion(PAO) for getting VAN obliteration.PAO sometimes causes medulla infarction that was affected daily life. Our report purpose is revealed the results and morbiditys of endovascular therapy of unruptured intracranial VAN. METHODS This study is Retospective study, we check up medical records and images. Objective: From April 2001 to June 2016, Endovascular coil embolization for unruptured intracranial VANs in Our affiliated Hospital. we performed PAO for 42 cases and stent assisted coil embolization(SACE) for 31cases. Almost cases was received dual antiplatelet medication for more than 3 days of endovascular procedure. RESULTS In PAO cases, there is got complete obliteration of aneurysm at 98%. DWI finding is positive at 49%, 12 %(5 cases) develops medulla infarctions. In SACE cases, there is got complete obliteration of aneurysm at only 7%. But 6 months later, the Complete obliteration rate raises 68%. DWI finding is positive at 33%, one case develops brainstem infarction due to acute occlusion in stent. Two cases need retreatments.
