ObjectiveThe purpose of the current study was to evaluate the method and result of endovascular treatment for a giant unruptured dissection of the basilar artery(BA).MethodsA 14-year-old boy underwent computed tomography(CT)scan following a minor head trauma was incidentally found a lesion located anterior to brain stem.Further imaging with magnetic resonance imaging(MRI)，computed tomography angiography(CTA)and digital subtraction angiography(DSA)were consistent with a diagnosis of giant unruptured dissection of BA.The patient was initially treated with BA stenting of the dissected lumen.The follow-up DSA obtained 15 days later showed thrombosis in dissected lumen and a reduction in diameter of the vessel wall.DSA obtained 3 months later revealed extension of the dissection inferiorly to involve the left vertebral artery(VA).The dissection expanded at the conjunction of VAs in the shape of ball.Therefore，coil embolization to partly occlude BA at the bottom of aneurysm was performed as a further treatment.ResultsThe prognosis was good.Follow-up DSA 6 months later demonstrated complete obliteration of the dissection and good compensative perfusion from extensively established collateral circulation.ConclusionFor young patients with isolated dissection of BA，coil embolization to partly occlude BA at the bottom of aneurysm might be a tolerable and effective approach，which takes effectprobably through resulting in the procedure of slow occlusion of BA.11 refs，5 figs.
