T1 Results from the Penumbra Pivotal Stroke Trial Substudy JF MD Conference Express YR 2010 FD SAGE Publications VO 10 IS 1 SP 21 OP 22 DO 10.1177/155989771001013 UL http://mdc.sagepub.com/content/10/1/21.abstract AB While the Penumbra Pivotal Stroke Trial demonstrated a recanalization rate of 81.6%, the rate of good clinical outcome, defined as a modified Rankin Scale (mRS) score =2, was relatively low (25%) [The Penumbra Pivotal Stroke Investigators. Stroke 2009]. This article discusses a subanalysis from the Penumbra Pivotal Stroke Trial, which evaluated whether a good initial noncontrast computed tomography and short time to recanalization predicted good clinical outcome in patients with acute ischemic stroke who were undergoing endovascular procedures.
