Parenchymal Hyperdensity on Computed Tomography After Intra-Arterial Reperfusion Therapy for Acute Middle Cerebral Artery Occlusion

Abstract

The presence of hyperdense areas was a significant risk factor for severe hemorrhagic transformations, although only 29.7% of patients with hyperdense areas had symptomatic hemorrhage. On the contrary, the absence of hyperdense areas was a reliable negative predictor for symptomatic hemorrhage.
