@Animalz – There’s no need to worry. As a med student, I’ve sat in on a dozen bronchial artery embolization (BAE) treatments. It’s a nonsurgical treatment for a condition called hemoptysis, and it’s often very effective. Your grandmother should see an improvement in her condition after one treatment, with increased improvements after additional treatments.
The embolization procedure consists of a muscular injection and complete sedation through the use of intravenous drugs. Since this will be her first BAE procedure, the bronchial artery in question will be catheterized. Other arteries may also be catheterized, if they are also giving her problems.
Next, an embolization fluid made of polyvinyl alcohol particles will be pumped through the catheters. The fluid will block off the damaged parts of her arteries, which should reduce the amount of blood leaking into her lungs. If embolization needs to be done to large blood vessels, steel or platinum coils may be used instead of fluid.
The entire procedure is very closely monitored from start to finish. It may sound scary, but your grandmother will be sedated for the entire process, and won’t feel a thing. This procedure is very successful in treating medical conditions, so there’s no need to worry.
