[Pitfalls in mechanical recanalization].

Recently multiple studies demonstrated the advantage of mechanical thrombectomy after thrombotic stroke onset in proximal intracranial arteries over i.v. thrombolysis. In experienced stroke centers, recanalization rates of up to 90% can be achieved. This article is dealing with various pitfalls which could face the interventionalist during endovascular therapy and can complicate or even make the procedure impossible.
