Endovascular treatment of basilar artery dissection by stent deployment. A case report

We describe a 44 year-old woman with dissection of the distal third of the basilar artery presenting with subarachnoid haemorrhage. She was treated with a Neuroform stent (Boston Scientific), the first stent designed for intracranial navigation and recently approved by the FDA to treat wide-necked cerebral aneurysms and allow reconstruction of the internal lumen. In our patient, the dissection involved the origin of the anterosuperior cerebellar artery and the origin of the right posterior cerebral artery. The stent was positioned without complications during or after the procedure. Intra and periprocedural thrombolytic therapy was given followed by an antiaggregant (100 mg Aspirin) for a year after treatment. Subsequent angio-MR and angiographic monitoring disclosed resolution of the dissection and normalization of the basilar artery lumen. She currently lives a controlled but normal life.
