The fatality rate of an arteriovenous malformation (AVM) is difficult to determine because there is a lack of specific data on the long-term outcomes of individuals with this condition. However, research suggests that the fatality rate of AVMs is low, with most deaths occurring within the first year of diagnosis.
It is estimated that the overall mortality rate of AVMs is approximately 2.4%. This number includes deaths due to complications from the AVM itself, as well as those that may be caused by treatments such as surgery or embolization.
However, the mortality rate for each individual AVM can vary significantly depending on the size, location, and complexity of the AVM. Large, complex AVMs that are located in the brain or spinal cord are generally associated with a higher risk of death than smaller, less complex AVMs.
Additionally, the fatality rate of AVMs can be affected by the patient's age and overall health. Individuals who are older and have other health conditions, such as diabetes or cardiac disease, may be more likely to experience complications due to their AVM.
Overall, it is difficult to determine the exact fatality rate of AVMs due to the lack of long-term data. However, it is estimated that the overall mortality rate of AVMs is approximately 2.4%. This number can vary significantly depending on the size, location, and complexity of the AVM, as well as the age and overall health of the patient.
