Treatment The current treatment measures for the acute phase of spontaneous intraventricular hemorrhage can be broadly divided into two categories: medical treatment and surgical treatment. The commonly used surgical treatment modalities are ventricular drainage and craniotomy for hematoma removal, while intracerebral hematoma puncture and aspiration are less commonly used clinically. Since the advent of CT, the mortality rate of spontaneous intraventricular hemorrhage treated by internal medicine has decreased to 34.1%-57.1%, with an average of 38.4%. This is not due to a significant improvement in medical treatment measures, but rather to the increased detection of patients with mild spontaneous intraventricular hemorrhage and the ability to clearly diagnose and treat them in a timely manner. Indications: Internal medicine should be the first choice for all patients belonging to grade I. Specific indications for conservative medical treatment of spontaneous intraventricular hemorrhage include: 1. consciousness or haziness on admission; 2. clinical signs of mild or moderate brain localization with no tendency to deteriorate during conservative treatment; 3. blood pressure ≤ 26.7 kPa (200/120 mmHg) on admission; 4. no acute obstructive hydrocephalus or only mild hydrocephalus (ventriculo-cranial ratio of 0.15 to 0.23) of Primary intraventricular hemorrhage; 5. Midline structural displacement.
