Catheter-directed Embolization is a nonsurgical, outpatient treatment performed by an Interventional Radiologist using imaging to guide catheters or other instruments inside the vascular system. Through local anesthesia and optional mild IV sedation, patients are relaxed and pain-free during procedure. The Radiologist then uses coils, balloons, or particles to embolize (block) veins. By sealing a faulty vein or the blood flow to an abnormality, like a fibroid, it allows the body to help heal itself and redirect blood to where it is needed.
Common uses of this procedure are for to treat Uterine Fibroids, Pelvic Venous Insufficiency (PVI), Varicocele Veins, and Hereditary Hemorrhagic Telangiectasia, also known as Osler–Weber–Rendu disease.
