Background: This study aims to determine which factors increase the risk of intracerebral hemorrhage after tissue plasminogen activator (tPA) treatment in patients with acute ischemic stroke and to investigate whether there is a relationship between the need for antihypertensive therapy during and after tPA infusion and the risk of intracerebral hemorrhage. Materials and Methods: Consecutive patients who applied to our stroke center with acute ischemic stroke and received IV tPA treatment in the first 4.5 h between 2012 and 2020 were included in the study. The demographic data of patients, stroke risk factors, drugs used before the stroke, neurological examinations, cranial computed tomographys (CTs) before and after tPA, antihypertensive usage during IV tPA and in the 24-h period after treatment, hospital mortality rates, and modified Rankin Scale scores in the 3rd month were evaluated retrospectively. Patients with intracerebral bleeding were divided into groups according to bleeding subtypes and whether they were symptomatic. Results: Intracranial bleeding was detected in 48 of 214 patients included in this study. Nineteen of these (8.8%) were classified as symptomatic intracerebral hemorrhage according to the National Institute of Neurological Disorders and Stroke and 14 (6.5%) according to the definition of the European Cooperative Acute Stroke Study. In the multiple logistic regression analysis, intracranial bleeding was significantly associated with 24th h systolic blood pressure and the need for antihypertensive usage. Conclusions: Blood pressure regulation should be done carefully during tPA infusion and in the first 24 h. In addition, cranial CT scanning in patients who need antihypertensive usage may enable earlier detection of intracranial bleeding.
