What are the risks of venous malformation treatments?

So, the risk of treatment is one I, you always have to consider as a patient the risk, the benefits and the risks. And if you see a vascular specialist and they offer you treatment, it's largely because the benefits outweigh the risks in relation to your symptoms. And the risk, anytime there's a cut into the skin, there is a risk of bleeding, infection, having a scar. So the risks, anytime there's a cut in the skin, there is a risk of bleeding, having a scar, the risk of infection, and discomfort after the procedure. To reduce the risk of infection, the patients are given an antibiotic prior to the procedure. A more serious risk is developing a blood clot in the deeper veins of the body and this is again reduced by patients getting a blood thinner either in the form of an injection or a tablet after the procedure to reduce that risk. There may be some numbness in the skin and depending on what the option was in terms of injecting foam or excising the malformation there may be some numbness in the area of that skin where the procedure took place.
