title: [A Case of Vertebral Artery Stenosis Presenting with Progressing Stroke and Treated by Percutaneous Transluminal Angioplasty].
abstract: A 75-year-old man with a history of diabetes mellitus and hypertension was suffered from dizziness and vomiting and brought to the near-by hospital. MRI showed cerebellar infarction due to right vertebral artery stenosis. Despite best medical treatment, the infarction progressed day by day and he was transferred to our hospital five days later. Neurological examination showed mild disturbance of consciousness and right hemiparesis. Right vertebral angiography revealed high-grade stenosis accompanied with atherosclerosis at the V3-V4 portion. Percutaneous transluminal angioplasty (PTA) was performed with 2.5 mm×14 mm balloon with 6 atm dilation. Postoperative course was uneventful and no further stroke occurred after the treatment. PTA was effective for vertebral artery stenosis manifested with progressing stroke. The indication of stent placement for the cerebral artery should be prudent.
