Hemorrhagic transformation in acute ischemic stroke / 国际脑血管病杂志

ABSTRACT

The frequency and influence on prognosis of hemorrhagic transformation (HT) after acute ischemic stroke are still uncertain with mixed results in previous studies.Slight hemorrhage transformation may will not worsen stroke patients' short-and long-term prognosis,but some MRI studies suggest that HT may impede patients to get a dramatical improvement of neurological function.We aimed to determine the overall frequency of and risk factors for HT.More importantly,we discussed the mechanism,subtypes of HT and the influence of HT subtypes on prognosis.
