| Hi Terijo, I am sorry to hear that your son had a stroke. Is he taking an anticoagulant? That should keep him from making any more clots for now. If he is going to have the closure done, please get some allergy testing to make sure that he's not allergic to any of the components of the device. An allergist or dermatologist can easily do this, with skin patch testing that only takes a few days. Skin patch testing is now the protocol at the UCAL cardiac dept. You can ask your cardiologist which kind of implant they are going to use, and then your doctor can call the manufacturer of the device and find out what the components are, and then prepare the skin patch test. There is usually nickel in the implants, which can be a big problem for many people. The surgery itself is very simple, and is an outpatient procedure, and doesn't even require that you are put to sleep. Please keep us updated, and good luck! Solitaire |
