Final answer:
The etiology of an ischemic stroke includes cerebral aneurysm, cardiogenic embolic, intracerebral hemorrhage, and arteriovenous malformation.
Step-by-step explanation:
The etiology of an ischemic stroke includes:
- Cerebral aneurysm: Cerebral aneurysms are weak spots in the blood vessels of the brain that can rupture and cause a blood clot, leading to an ischemic stroke.
- Cardiogenic embolic: Cardiogenic embolism occurs when a blood clot forms in the heart and travels to the brain, blocking a blood vessel and causing an ischemic stroke.
- Intracerebral hemorrhage: Intracerebral hemorrhage refers to bleeding within the brain itself, which can disrupt blood flow and lead to an ischemic stroke.
- Arteriovenous malformation: Arteriovenous malformation is an abnormal tangle of blood vessels in the brain that can increase the risk of blood clots and ischemic strokes.
