Thrombelastography does not predict clinical response to rtPA for acute ischemic stroke.

Thrombelastography (TEG) measures coagulation in venous blood. We hypothesized that TEG, by reflecting clot subtype and ex vivo fibrinolysis, might predict fibrinolytic response to tPA as reflected by rapid clinical improvement or hemorrhagic transformation of the infarct. 171 acute ischemic stroke patients treated with tPA were prospectively enrolled.

Impact of Telemedicine on Access to Acute Stroke Care in the State of Texas.

Background: To examine the impact of telemedicine on access to acute stroke care and expertise in the state of Texas.

Methods: Texas hospitals were surveyed using a standard questionnaire and categorized as: (1) stand-alone Primary Stroke Centers not using telemedicine for acute stroke care, (2) Primary Stroke Centers using telemedicine for acute stroke care, (3) non-Primary Stroke Center hospitals using telemedicine for acute stroke care, or (4) non-Primary Stroke Center hospitals not using telemedicine for acute stroke care. Population data were obtained from the US Census Bureau and the Neilson Claritas Demographic Estimation Program.

Thrombelastography detects possible coagulation disturbance in patients with intracerebral hemorrhage with hematoma enlargement.

Background And Purpose: Intracerebral hemorrhage (ICH) has high morbidity, and hematoma enlargement (HE) causes worse outcome. Thrombelastography (TEG) measures the dynamics of clot formation and dissolution, and might be useful for assessing bleeding risk. We used TEG to detect changes in clotting in patients with and without HE after ICH.
