(therapeutic embolization) n. the introduction of embolic material to reduce or completely obstruct blood flow in such conditions as congenital arteriovenous malformations (see angioma), angiodysplasia, malignant tumours, or arterial rupture. Under X-ray screening control, a catheter is guided to the artery supplying the affected area and occluding material, such as microspheres, metallic coils, or PVA (polyvinyl alcohol) foam, is injected. The procedure may treat the underlying problem or simplify subsequent surgery. See also uterine artery embolization.
