Subventricular hemorrhage on the left side of the neonate’s body is usually a mild hemorrhage and does not usually have sequelae. Neonatal left-sided subventricular hemorrhage can be caused by birth injury, etc. It is classified into four grades, with Grade I being the least severe type and getting worse as the grade increases. Grade 1 means that there is no ventricular dilatation or parenchymal hemorrhage, and the condition usually recovers on its own with regular observation, and usually does not require any special treatment and does not leave any after-effects. However, if a newborn with Grade 1 left subventricular hemorrhage is found, it is necessary to consult a doctor in time to evaluate the newborn’s specific situation under the supervision of the doctor, so as to promote the absorption of the hemorrhage as soon as possible, so that the baby can recover as soon as possible, and the parents don’t need to worry too much.
