From: The experiences of balloon-expandable stent in symptomatic stenosis of middle cerebral artery
A 51-year-old man with a stroke. a DSA shows severe stenosis (about 90 %) in the M1 portion of the left MCA, b the BES is positioned at the lesion, and the micro wire is anchored in the distal branch of the MCA, then the balloon is expanded gradually, c DSA shows excellent recanalization of the diseased segment immediate post-procedural, d at the 8 months, the thrombus blocked the artery in the stent completely.
