Basilar artery angioplasty is a mechanical procedure to treat basilar artery stenosis (narrowing of the artery). The basilar artery is an important artery in the brain as it brings blood to some of its most critical parts such as the the breathing center, the awareness center, and portions of the nerves that bring information to and from the entire body. After an initial series of basilar artery stent angioplasty indicated a high technical success rate and minimal morbidity, subsequent reports suggested significant procedural risks. We retrospectively reviewed our experience with basilar artery stent placement to assess complications and clinical outcomes.
In the Shin-Tokyo Hospital, Matsudo-city, Chiba, Japan, two cases of patients underwent stent-assisted percutaneous transluminal angioplasty for intracranial vertebral artery (VA) and basilar artery (BA) stenosis. Before the procedure, they presented with sudden onset of vertigo and right hemiparesis. Vertebral angiographies revealed severe proximal BA stenosis (case 1) and intracranial VA stenosis (case 2). They underwent angioplasty and stenting, with excellent angiographic results. The availability of new flexible intravascular stents, allowing access to tortuous proximal intracranial vessels, provides a new therapeutic approach for patients with vertebral and basilar artery stenosis.
