Do AVMs Always Rupture?
What is an AVM?
An AVM, or arteriovenous malformation, is a tangle of abnormal blood vessels in the brain or spine. These vessels can be weak and prone to rupture, resulting in life-threatening bleeding and stroke.
Do AVMs Always Rupture?
The answer to this question depends on the size and location of the AVM, as well as the patient's medical history. Generally speaking, small AVMs are less likely to rupture than large AVMs. However, any AVM, regardless of size, can rupture at any time.
What Are the Risk Factors for AVM Rupture?
The risk of an AVM rupturing increases with age, as the vessels become weaker over time. Other risk factors for AVM rupture include high blood pressure, head trauma, and pregnancy.
What Are the Symptoms of AVM Rupture?
The symptoms of an AVM rupture depend on the location of the rupture and the amount of bleeding. Common symptoms include headache, confusion, seizures, nausea, dizziness, and double vision.
What Are the Treatment Options for AVM Rupture?
Treatment for AVM rupture depends on the severity of the bleed. If the rupture is small, the patient may be able to be monitored with imaging studies and medications. In more severe cases, surgery may be necessary to repair the blood vessels and prevent further bleeding.
