Nonocclusion and Spontaneous Recanalization Rates in Acute Ischemic Stroke

Abstract
SPONTANEOUS recanalization (SR) is an intriguing phenomenon in acute ischemic stroke. Cerebral angiographic and autopsy studies have clearly documented its occurrence.1 Assigning accurate rates of SR has been hindered by several factors, including the complexity of stroke as a disease process and the heterogeneity of available studies.
