case_images: Case 1. (a) Superior mesenteric arteriograph (venous phase) demonstrating a spleno-renal (white arrow) and spleno-retroperitoneal shunt (black arrow) and an undetected portal vein trunk. There is enough distance to allow disconnecting the mesenteric-portal blood flow from the systemic circulation while preserving the shunt. (b) Schemas of the hemodynamics before selective embolization of the splenic vein for shunt-preserving disconnection of the portal and systemic circulation. Arrows show the direction of the blood flow in the splenic vein and the superior mesenteric vein into the systemic circulation over a spleno-renal shunt

case_images: In both cases, the venous phase of superior mesenteric arteriography demonstrated a spleno-renal and a spleno- retroperitoneal shunt, and an undetected portal vein trunk (Fig. 1). There was enough distance to allow disconnection of the mesenteric-portal blood flow from the systemic circulation while preserving the shunt (Fig. 1a).

case_images: Splenic venography revealed a spleno-renal and a spleno-retroperitoneal shunt (Fig. 2).
case_images: Case 1. (a) After embolization with two coil anchors, nine metallic coils, and 10 microcoils the venous phase of superior mesenteric arteriography demonstrated a portal vein trunk (black arrow) toward the liver. (b) Schemas of the hemodynamics after selective embolization of the splenic vein for shunt-preserving disconnection of the portal and systemic circulation. Arrows show the direction of the blood flow in the splenic vein into the systemic circulation over a spleno-renal shunt. The blood flow in the superior mesenteric vein is redirected into a portal vein and a portal vein trunk toward the liver
