Figure 3 Axial contrast-enhanced CT scan showing superior mesenteric vein thrombosis with extension into the splenic vein. Axial contrast-enhanced CT scan of the abdomen reveals a hypodense intravascular filling defect within the superior mesenteric vein (SMV), extending into the splenic vein. The thrombus appears as a non-enhancing region within the contrast-filled vessel lumen, indicating obstruction of venous flow. The involvement of multiple major mesenteric vessels suggests an extensive thrombotic event, which significantly increases the risk of intestinal ischemia.
