Flying with a brain AVM (arteriovenous malformation) can be a complex and serious matter, and ultimately it is up to your doctor to determine whether it is safe for you to fly. Generally speaking, if your AVM is deemed stable and doesn’t pose a risk for hemorrhagic stroke, then you may be able to fly. However, if your AVM is considered to be high risk, then you should not fly or exercise vigorously until the AVM is treated.
When considering whether to fly with an AVM, the most important factor is your individual medical situation. If your AVM is stable, your doctor may allow you to fly, but you should still check with your doctor beforehand. He or she may recommend that you take certain precautions, such as avoiding straining or rapid changes in altitude, which could put you at risk of experiencing a hemorrhagic stroke.
If your AVM is not stable, it is highly recommended that you avoid flying until your AVM is treated. Flying with an unstable AVM can increase your risk of experiencing a hemorrhagic stroke, which can be fatal.
Ultimately, it is important to speak to your doctor before deciding to fly with an AVM. He or she will be able to assess your individual situation and provide you with personalized advice on whether it is safe for you to fly.
