title: Endovascular coil embolization of parent artery for giant intracranial basilar artery dissection: a case report.
abstract: Isolated dissection of the basilar artery (BA) is rare and still a big challenge     regarding treatment. The suitable therapeutic strategies for dissection of the     BA remain controversial. We report the case of a young patient with a giant     unruptured dissection of the BA successfully treated by endovascular coil     embolization. A 14-year-old male who underwent computed tomography (CT) scan     following a minor head trauma was incidentally found to have 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 the BA. The     patient was initially observed conservatively. The follow-up DSA obtained 3     months later revealed extension of the dissection inferiorly to involve the left     VA. The dissection expanded at the conjunction of VAs in the shape of ball.     Therefore, coil embolization to occlude BA at the bottom of aneurysm was     performed as a further treatment. Follow-up DSA 6 months later demonstrated     complete obliteration of the dissection and good compensative perfusion from     extensively collateral circulation. For young patients with isolated dissection     of the BA, coil embolization to occlude BA at the bottom of aneurysm might be     tolerable and effective.
