Objective: Intravenous tissue plasminogen activator (IV tPA) is an approved treatment for acute ischemic stroke. However, the effects of decompressive craniectomy (DC) after IV tPA administration for ischemic stroke are still largely unknown. The aim of this study was to investigate the safety and outcomes of DC after IV tPA administration.
Methods: We retrospectively reviewed patients who underwent DC for malignant hemispheric infarction. We compared 20 patients who underwent DC after IV tPA administration with another 20 patients who underwent DC without prior IV tPA administration.
Results: The patient characteristics did not differ between the DC patients with and without prior IV tPA administration. New intracranial bleeding or worsening of pre-existing ICH occurred in two patients (10%) in each group. Furthermore, the rates of an mRS score of 4-6, 5 or 6, and 6 did not differ significantly between the two groups.
Conclusion: DC may be a safe and useful surgical procedure for space-occupying edema after IV tPA administration for acute stroke.
