Abstract

The treatment of acute ischemic stroke by mechanical thrombectomy has been revolutionary, however most of the clinical trials were done with the use a stent retriever. At the same time, an alternative technique of thrombectomy through direct aspiration with a large bore distal access catheter at the face of the clot is rapidly gaining popularity. Nonetheless, the data supporting this new technique is not yet as mature as that available on stent retrievers. This review is a critical analysis of the evidence supporting the principle of direct aspiration thrombectomy and a discussion of its potential strengths and weaknesses in comparison to the available studies on stent retrievers. While this is by no means a conclusive review, it should serve as a yardstick of where the science is currently, and what are the next trials that are necessary.
