Abstract: Cerebral hemorrhage and visceral hemorrhage are the most serious complications of primary immune thrombocytopenia （ITP），which are commonly seen in hematonosis patients，with extremely high mortality.We reported the clinical diagnosis and treatment of one case of ITP with multiple intracranial hemorrhages.The patient had been diagnosed with thrombocytopenic purpura for more than 20 years.During this period，she had suffered from 3 times of intracerebral hemorrhage involving multiple compartments and one time of gastrointestinal hemorrhage.As the amount of bleeding was not large，she has good survival，which is rarely seen clinically and may be related to the actions of other hemostatic mechanisms.Moreover，on the basis of the reviewing of related studies，we found some effective prevention and treatment measures for ITP，in order to offer some assistance for clinicians.
