Key result
Empiric tPA achieves ROSC in refractory cardiac arrest but causes severe intracranial hemorrhage.
Why the study?
Intracranial hemorrhage is a rare but serious complication following tPA administration in refractory out-of-hospital cardiac arrest, with limited practical imaging options in this setting.
Case Report (n=1)
Empiric administration of tPA for refractory out-of-hospital cardiac arrest in patients with a history of intracranial hemorrhage carries a significant risk of fatal intracranial bleeding.
Empiric tPA risks catastrophic intracranial hemorrhage in refractory arrest; hypothesis-generating for risk-stratified trials.
Tissue plasminogen activator (TPA) is indicated as an empiric therapy for refractory out-of-the-hospital cardiac arrest for suspected pulmonary embolism and myocardial infarction. Intracranial hemorrhage following TPA administration is a rare complication resulting in increased morbidity and mortality. A history of intracranial bleed, oral anticoagulant use prior to hospital admission, low body weight, and unstable hypertension with blood pressure above 180/110 mmHg at the time of presentation are associated with intracranial bleeding following tPA administration. Dedicated imaging including a Computed Tomography of the head without contrast, while feasible for patients presenting with acute stroke, is impractical in the setting of cardiac arrest. Here we report a case of 66 years old patient who presented in context of refractory cardiac arrest with recurrent PEAs with interval return of spontaneous circulation (ROSC) and was given tPA with eventual ROSC. He was subsequently found to have both a subarachnoid and intraventricular hemorrhage.

Acharya et al. (2024) conducted a case report in Refractory out-of-hospital cardiac arrest (n=1). Tissue Plasminogen Activator (TPA) was evaluated on Intracranial hemorrhage (subarachnoid and intraventricular hemorrhage). Empiric administration of 50 mg of tissue plasminogen activator in a 66-year-old man with refractory cardiac arrest resulted in ROSC but led to severe subarachnoid and intraventricular hemorrhage.
