    Unruptured intracranial aneurysm (UIA) is considered to be a relative contraindication for acute ischemic stroke (AIS) intravenous thrombolysis (IVT)
    .


    However, there are currently limited data on the risk of UIA rupture after IVT


    Unruptured intracranial aneurysm (UIA) is considered to be a relative contraindication for acute ischemic stroke (AIS) intravenous thrombolysis (IVT)

    The study conducted a prospective cohort study of consecutive patients who were treated at comprehensive stroke centers from 2005 to 2019
    .


    The radiation reports and records of the Finnish Health Care Registry were evaluated to identify UIAs patients among all AIS patients who received IVT treatment at the center


    The study conducted a prospective cohort study of consecutive patients who were treated at comprehensive stroke centers from 2005 to 2019


    The study analyzed hospital ICH caused by UIA rupture after IVT, as well as hospital symptomatic ICHs (ECASS-2 criteria, that is, NIH stroke scale score increase ≥ 4 points) and any hospitalized ICH
