Complications that require management include hydrocephalus and vasospasm. If the stream of blood is directed toward the brain, it may cause intracerebral and intraventricular hemorrhage. Subarachnoid hemorrhage is a medical emergency. After rupture, the location of the blood or hematoma can help determine the site of the ruptured aneurysm in the majority of cases: An intraparenchymal hematoma adjacent to the ruptured aneurysm is known as a jet hematoma or flame hemorrhage, caused when an aneurysm abuts a lobe and at the time of rupture the pressure of the blood leaving the aneurysm dissects into the brain parenchyma.
