Mechanisms of hemorrhagic transformation after tissue plasminogen activator reperfusion therapy for ischemic stroke.
Reperfusion therapy with tissue plasminogen activator (tPA) is a rational therapy for acute ischemic stroke. Properly titrated use of tPA improves clinical outcomes. However, there is also an associated risk of hemorrhagic transformation after tPA therapy. Emerging data now suggest that some of these potentially neurotoxic side effects of tPA may be due to its signaling actions in the neurovasc...
متن کاملPostischemic hyperperfusion on arterial spin labeled perfusion MRI is linked to hemorrhagic transformation in stroke.
The purpose of this study was to investigate the relationship between hyperperfusion and hemorrhagic transformation (HT) in acute ischemic stroke (AIS). Pseudo-continuous arterial spin labeling (ASL) with background suppressed 3D GRASE was performed during routine clinical magnetic resonance imaging (MRI) on AIS patients at various time points. Arterial spin labeling cerebral blood flow (CBF) m...
متن کاملEarly Rivaroxaban Use After Cardioembolic Stroke May Not Result in Hemorrhagic Transformation
Patients with atrial fibrillation who have suffered a transient ischemic attack (TIA) or ischemic stroke are at high risk for recurrence and require long-term anticoagulation. The optimal timing of anticoagulation after an ischemic stroke is controversial. Although anticoagulation in acute stroke patients is associated with reduced early stroke recurrence rates, these benefits are offset by a c...
متن کاملPostcarotid endarterectomy hyperperfusion or reperfusion syndrome.
BACKGROUND AND PURPOSE Hyperperfusion syndrome (HS) after carotid endarterectomy (CEA) has been related to impaired cerebrovascular autoregulation in a chronically hypoperfused hemisphere. Our aim was to provide new insight into the pathophysiology of the HS using magnetic resonance imaging (MRI) studies with diffusion-weighted imaging (DWI) and perfusion-weighted imaging (PWI). METHODS Five ...
متن کاملCerebral Hyperperfusion Syndrome After Angioplasty
Cerebral hyperperfusion syndrome (CHS) was first described by Sundt et al. (1981) as a clinical syndrome following carotid endarterectomy (CEA) characterized by headache, neurological deficit, and epileptic seizures that is not caused by cerebral ischemia. This chapter deals with this uncommon but not exceptional complication of endovascular treatment of the arteries that supply the brain. We u...
