View larger version (83K): [in this window] [in a new window]   Fig 1. A, Left internal carotid artery cerebral angiography demonstrates severe stenoses of the ACA and MCA, which are confluent at the carotid terminus. B, After angioplasty alone of the ACA and stent-assisted angioplasty of the MCA, there is normal caliber of the previously stenosed ACA and MCA. Arrows denote the proximal and distal ends of the stent.

A, Four months after the initial procedure, left internal carotid cerebral angiography demonstrates the ACA to remain normal in caliber. There is a severe recurrent stenosis within the stented segment of the MCA. B, After angioplasty of the severe in-stent restenosis, the left MCA demonstrates markedly improved vessel caliber and improved flow dynamics.
