<jats:p><i>Background:</i> Predictors of outcome and safety in intravenous thrombolysis within 3 h in clinical routine is a matter of ongoing debate. Available reports contain small patient numbers or summarize heterogeneous multicenter data. <i>Methods:</i> Four hundred and fifty patients received intravenous thrombolysis within 3 h after stroke. Pretreatment NIHSS score and detailed medical history were analyzed. Noncontrast CT was performed before thrombolysis, 24–36 h later and in case of clinical deterioration. Symptomatic intracranial hemorrhage (SICH; any bleeding with an NIHSS increase of ≧4 points) and clinical outcome (modified Rankin Scale, mRS) after 3 months were recorded. Logistic regression identified parameters predictive of independence (mRS 0–2) and SICH. <i>Results:</i> Median onset to admission, door to needle and onset to treatment time was 75, 50 and 135 min, respectively. Direct presentation by emergency service (64%) was the fastest way of referral. Median pretreatment NIHSS was 11 points. Independence (mRS 0–2) was reached by 53%. Mortality was 11% (7% intracerebral, 4% extracerebral complications). Logistic regression identified low NIHSS, low age and absent diabetes as predictors of independence. Overall hemorrhagic complications and SICH were found in 18 and 4% of the patients, respectively. Extracerebral bleeding complications and allergic reactions were found in 3 and 1%, respectively. <i>Conclusion:</i> This largest single center report presents a sample in the range of the 3 h rt-PA cohort of all randomized controlled trials. Outcome was comparable to randomized studies with a higher rate of independence and a lower rate of mortality and SICH.</jats:p>
