Which embolic material is best suited for which embolization procedure?

Various embolization cases are described, and these require certain embolization materials. In our experience Gelfoam particles are very well suited for gastrointestinal tract lesions. Ivalon shavings gave excellent results in congenital arteriovenous malformations with permanent occlusions. Bristle brushes are a new device for larger artery occlusion. Stainless steel coils in combination with silk tufts proved thrombosis of large AV fistuals or of aneurysms particularly of the splenic artery.
