Ruptured aneurysms with dilated pupils have a chance of survival with aggressive treatment.
The dilated pupil of a ruptured aneurysm is usually a sign of a more serious condition, which is usually caused by aneurysm rupture and bleeding, leading to increased intracranial pressure and then herniation of the brain.
Surgery to remove the hematoma and clip the ruptured aneurysm can prevent the aneurysm from rupturing and bleeding again, and debulking can prevent the brain hernia from further aggravating. Meanwhile, active medication, such as mannitol to lower the cranial pressure, nimodipine to prevent vasospasm, etc., may reduce the symptoms of brain hernia further.
Generally after active treatment patients have a chance to survive, but often are left with more obvious sequelae, such as hemiplegia, aphasia and so on. However, rupture without timely treatment often results in life-threatening conditions in the short term, so it is important to treat aneurysm rupture in a timely manner.
