title: Positional vertebrobasilar transient ischaemic attacks treated with vertebral angioplasty.
abstract: We report the case of a man presenting with a brain-stem stroke from which he recovered fully, who developed right-sided weakness and numbness on walking despite no demonstrable postural fall in arterial blood pressure. Angiography revealed an occluded left vertebral artery, a tight stenosis at the origin of the right vertebral artery and non-patent left posterior communicating artery. Percutaneous transluminal angioplasty to the right vertebral stenosis results in a good angiographic result, and remission of symptoms which has persisted for 1 year. Identification of such patients with vertebrobasilar positional haemodynamic symptoms due to a focal stenosis is important as angioplasty offers an effective therapeutic option.
