[Clinical case of the month. Cerebrovascular accident related to arterial brachiocephalic trunk stenosis].

The authors report the case of a 47-year old man, admitted for syncope and left-sided motor deficit. Diagnostic investigations revealed a right middle cerebral artery embolic stroke, secondary to a critical stenosis of the arterial brachiocephalic trunk, harboring a floating thrombus. The treatment options for occlusive lesions of the brachiocephalic trunk are discussed, as well as the optimal delay between stroke and brain revascularization.
