ABSTRACT
OBJECTIVE: Increased use of systemic thrombolysis, demographic changes, and higher chances of surviving first-ever strokes all lead to an increasing number of patients with recurrent stroke. However, data on repeated thrombolysis are limited. Here, we report on the safety and clinical effects of repeated intravenous recombinant tissue-type plasminogen activator (rt-PA) treatment in a large consecutive cohort of stroke patients. METHODS: We identified all stroke patients who received repeated thrombolysis. We determined safety and 3-month clinical outcome after the first and second thrombolysis. All patients received follow-up brain imaging. Good clinical outcome was defined as a modified Rankin Scale of 0-2 or recovery to the prestroke status. RESULTS: In total, 24 patients were included (i.e. 1.5% of all stroke patients treated with rt-PA at our center who survived the first treatment; male 45.8%; median age at first event: 74.5 years). No allergic or anaphylactic reactions were recorded after the first time of treatment, but oral angioedema developed once during the second treatment. No symptomatic intracerebral hemorrhage was observed. Clinical outcome was good in 75.0% after the first, but in only 41.7% after the second treatment (p = 0.021). CONCLUSIONS: Repeated thrombolysis was not associated with a higher rate of complications. However, the clinical outcome appears to be less satisfactory than after the first treatment.
