Vascular anomalies associated with hepatic shunting

Figure 8 Intravascular closure. A: Angiography showing a large congenital extrahepatic porto-systemic shunts (CEPSS) Type II (arrow); B: Balloon occlusion of the shunt revealing multiple large intrahepatic collateral vessels (arrows) (CIPSS Type IV); C: Anteroposterior; D: Lateral views of repeat angiography several months post partial occlusion of shunt showing improvement in portal venous flow after partial occlusion with better visualization of the right portal vein (chevron). Occlusion device not seen.
