Intravenous thrombolysis on early recurrent cardioembolic stroke

Abstract

Early recurrent cardioembolic stroke on the previously unaffected side has very rarely been reported during or after intravenous recombinant tissue plasminogen activator for acute ischemic stroke. For these cases, thrombolysis guidelines lack any clear recommendation. We report two cases of thrombolysed stroke patients, with paroxysmal atrial fibrillation but normal sinus rhythm on admission, who respectively developed recurrent ischemic stroke within few hours after complete improvement and during intravenous recombinant tissue plasminogen activator infusion. Intravenous thrombolysis was successfully repeated after echocardiographic evidence of left appendage thrombus in the first case and discontinued before complete administration in the second.
