Recanalization is the important outcome measure for acute stroke therapy. Several methods of recanalization assessment are used in clinical practice, but few studies have addressed their reliability.
We, therefore, sought to assess interobserver reliability of the diagnosis of intracranial artery recanalization following interventon by using TIMI criteria. The diagnosis of recanalization after interventional procedures was found to have poor interobserver agreement between 2 experienced neuroradiologists.
TIMI criteria, therefore, do not permit reliable comparison of the efficacy of recanalization therapy among different studies.
