Transient ischemic attack associated with stenosis of accessory middle cerebral artery.

Establishing the mechanism of ischemia in patients with cerebrovascular ischemia is important in determining prognosis as well as the therapeutic approach. Recurrent transient ischemic attacks in a patient with accessory middle cerebral artery described by Gao et al. pose important questions. The underlying mechanisms responsible for cerebral ischemia remain unclear. I propose some of the possible methods to elucidate the pathogenic mechanisms for optimization of treatment and secondary prevention. 2009. Published by Elsevier B.V.
