Flow-controlled silicone fluid embolization.
Flow-controlled silicone fluid embolization is a technique that can be useful in situations where selective injection cannot be achieved, but where the proximal part of the feeding vessel must be preserved. It consists of a modified double-lumen balloon catheter and silicone fluid made radiopaque with tantalum powder with a predetermined viscosity and vulcanization time. Flow control by manipulation of the balloon in the proximal artery permits the distribution of emboli to desired sites in distal arteries. A case is described and other details offered about this technique that may be valuable for special situations.
