Proposal of a new classification scheme for complete portal vein thrombosis and its clinical significance: A retrospective study

Figure 3 Chronic portal vein thrombosis. A: Contrast-enhanced abdominal computed tomography (coronal view): A somewhat low-density vascular shadows in the main trunk of the portal vein and the superior mesenteric vein, with relatively uniform density and consistent vascular morphology. Numerous collaterals had formed, and vessel wall thickening was observed (orange arrows); B: Histological analysis with hematoxylin and eosin (HE) staining: Consistent with the imaging findings, alternating layers of red blood cells and fibrin are observed (scale bar, 100 μm); C: Histological analysis with HE staining: Consistent with the imaging findings, collateral vessel formation is evident surrounding the thrombus, accompanied by wall thickening (scale bar, 100 μm).
