title: Safety of thrombolysis in acute ischemic stroke: a review of complications, risk factors, and newer technologies.
abstract: Intravenous recombinant tissue plasminogen activator (r-tPA) was approved for use in acute ischemic stroke in the United States in 1996. Approximately 2% to 5% of patients with acute ischemic stroke receive r-tPA. Complications related to intravenous r-tPA include symptomatic intracranial hemorrhage, major systemic hemorrhage, and angioedema in approximately 6%, 2%, and 5% of patients, respectively. Risk factors for symptomatic hemorrhage include age, male gender, obesity, increased stroke severity, diabetes, hyperglycemia, uncontrolled hypertension, combination antiplatelet use, large areas of early ischemic change, atrial fibrillation, congestive heart failure, and leukoariosis. A risk factor for angioedema is the use of angiotensin-converting enzyme inhibitor. Risk assessment scores, novel imaging strategies, and telemedicine may offer methods of optimizing the risk-benefit ratio.
