Overview
Portal vein thrombosis may be classified according to the extension into 4 groups:[1][2]
- Confined to the portal vein beyond the confluence of the splenic vein
- Extended to the superior mesenteric vein, but with patent mesenteric vessels
- Extended to the whole splanchnic venous system, but with large collaterals
- Extended to the whole splanchnic venous system with only fine collaterals

Based on the duration of symptoms, portal vein thrombosis may be classified as either acute or chronic.
Classification
- Portal vein thrombosis may be classified according to the extension into 4 groups:[1][2]
- Confined to the portal vein beyond the confluence of the splenic vein
- Extended to the superior mesenteric vein, but with patent mesenteric vessels
- Extended to the whole splanchnic venous system, but with large collaterals
- Extended to the whole splanchnic venous system with only fine collaterals
- Based on the onset of symptoms, portal vein thrombosis may be classified as either acute or chronic.[3]
- Acute portal vein thrombosis is defined as duration of symptoms <60 days and absence of portal carvernoma and portal hypertension.
- Chronic portal vein thrombosis is defined as duration of symptoms >60 days and/or presence of portal carvernoma and portal hypertension.
