Anchor technique: Use of stent retrievers as an anchor to advance thrombectomy catheters in internal carotid artery occlusions.

In three recent cases of acute complete internal artery occlusions, we used stent retriever deployed through the mechanical aspiration/distal access catheters to achieve recanalization. In all cases the stent retriever was used as an anchor and supplemented mechanical thrombectomy. This report describes the technical details of the procedure and presents an alternative plan of action in difficult cases when standard thrombectomy techniques do not work.
