Endovascular therapy is frequently the method of treatment in such situations but there remains a chance of incomplete recanalization. Successful recanalization of the proximal aspect of the occlusion may allow for endogenous thrombolysis and facilitate further endogenous recanalization of any residual MCA occlusion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Consecutive patients with acute ischemic stroke undergoing endovascular therapy for tandem extracranial ICA\u2013MCA or contiguous intracranial ICA\u2013MCA occlusions were retrospectively analyzed.
