Hemorrhagic transformation is one of the serious complications of intravenous thrombolysis with tissue plasminogen activator (t-PA), and the vast majority of currently published studies have focused on reducing or preventing hemorrhagic transformation after thrombolysis (17, 18), and our team previously reported higher fibrinogen in HT patients who did not receive thrombolysis (19), However, there is currently limited research comparing fibrinogen with different types of HT (spontaneous hemorrhagic transformation and hemorrhagic transformation after mechanical thrombectomy). Here, PLAT is linked to hematocrit.
