A 65-year-old male patient was referred with a recurrent stroke due to right vertebral artery stenosis and had also occlusion at right internal carotid artery and left vertebral artery (a and b). After undersized balloon angioplasty with Gateway an abnormal location of the tip of the microwire in anterior inferior cerebellar artery (AICA) was detected (c and d). An Enterprise stent was deployed and after deployment digital subtraction angiography (DSA) demonstrates near 10% residual stenosis (e). After deployment of the stent, a selective angiography of the AICA was performed due to suspicion of a microwire perforation and DSA demonstrates extravasation from a small branch of the AICA (f). Coil embolization was performed and on the completion of DSA total embolization of the extravasation and almost no residual stenosis at vertebral artery was observed (g).
