Abstract

We present a case of successful retrieval of an intracranial stent using a snare wire. A 52-year-old woman presented with left border zone infarction. On cerebral angiography, the C6 segment of the left internal carotid artery (ICA) showed significant stenosis. We attempted stenting of the lesion, although stent dislodgement occurred in the ICA C4 segment. We successfully removed it using a snare loop, and there were no complications during the procedure.

  Fig. 1 A. Cerebral angiography shows severe stenosis of the left internal carotid artery (ICA) C6 segment.B. Control angiography shows partial recanalization of stenotic segment afeter balloon angioplasty using a 2.5/20mm Ryujin balloon (Terumo, Japan).C. A 4.0×20 mm Neuroform stent was delivered to the distal ICA. However, a dislodgement of the stent occurred and the stent was localized in the ICA C4 segment.D. Stent evacuation was performed using a snare loop. On fluoroscopy, arrowheads indicate proximal and distal marker of Neuroform stent, and the arrow indicates a snare loop.E. The stent was successfully retrieved.F. Follow-up left ICA angiogram shows no significant complications in the distal ICA.
