Intraventricular hemorrhage is a serious class of intracranial hemorrhagic disease with severe disease and high mortality. The ventricular system is an important anatomical structure in the deep part of brain tissue, and the normal properties and circulation of cerebrospinal fluid play an important role in maintaining normal brain function. Blood entering the ventricular system induces intracerebroventricular inflammation; the blood clots formed in the ventricular system also easily produce serious complications such as hydrocephalus and intracranial hypertension that endanger patients’ lives.
Intraventricular hemorrhage can be divided into primary and secondary according to the primary site of hemorrhage. In primary intraventricular hemorrhage, the hemorrhagic focus is located within the ventricular system. Common causes of hemorrhage include hypertension, vascular malformation, aneurysm, MOYAMOYA disease, coagulation abnormalities and trauma, and the early mortality rate is 36-60%. Although the early mortality rate of primary intraventricular hemorrhage is high, because such patients generally do not have primary brain tissue damage, if they can safely survive the acute phase after hemorrhage with reasonable treatment, the survivors generally have a better recovery of neurological function.
