|AVM: A congenital tangle of blood|
vessels which can cause bleeding, pain
or other serious medical problems
The main vessels feeding each hemisphere are the carotid arteries, which also supply blood to the eyes. The investigators found that in one patient, eye temperature on the side of the AVM was lower than the other, and this temperature difference disappeared after surgical removal of the AVM. They now plan to see if eye temperature difference can be used as a surrogate measure of AVM size or flow, and whether a resolution of eye temperature difference could be useful as an adjunct marker of the success of AVM treatment.
