“…The most important part to treat patients with severe IVH is to remove IVH as soon as possible, dredge cerebrospinal fluid (CSF) circulation, prevent intracranial hypertension, and minimize secondary brain damage. In the traditional treatment, extraventricular drainage can dredge the CSF circulation and reduce the intracranial pressure, but with a high incidence of rebleeding and intracranial infection (Ge et al, 2019; Masoom Abbas, Gopal Varma, Sankar, & Pai, 2019). Therefore, it is always necessary to find a safe and effective treatment for patients with severe IVH in order to quickly eliminate ventricular hemorrhage and prevent recurrent bleeding.…”
