Acute ischemic stroke successfully treated using sequenced intravenous and intra-arterial thrombolysis and argatroban...

Direct thrombin inhibitors, a class of anticoagulants distinct from heparins, have not been evaluated for immediate use after thrombolytic therapy in acute ischemic stroke. We report a case of ischemic stroke and prothrombotic state treated using sequenced intravenous and intra-arterial thrombolytic therapy and argatroban anticoagulation.

A 19-year-old man with a complicated history of recurrent life-threatening thrombosis presented at the emergency department with acute ischemic stroke. The patient received standard-dose intravenous alteplase starting 2.25 hours after symptom onset without change in his global aphasia and right hemiparesis. Five hours after symptom onset, intra-arterial reteplase was administered for treatment of a left internal carotid "T" occlusion, with successful recanalization of the left internal carotid artery, A1 and M1 segments, and right middle cerebral anterior division and with improvement in symptoms. Argatroban therapy was started after completion of intra-arterial thrombolysis, i.e., 8.5 hours after symptom onset, and was maintained for 14 days. Although the patient sustained a small left basal ganglia infarct, he improved significantly over the course of therapy and was discharged to home without bleeding or further thrombotic episodes.

Sequenced intravenous and intra-arterial thrombolytic therapy and argatroban anticoagulation was used successfully to safely treat a patient with ischemic stroke and comorbid prothrombotic state within 8.5 hours of symptom onset.
