Overview
Portal vein thrombosis may be classified according to its extension into 4 groups including: Confined to the portal vein beyond the confluence of the splenic vein, extended to the superior mesenteric vein with patent mesenteric vessels, extended to the whole splanchnic venous system with large collaterals, and extended to the whole splanchnic venous system with only fine collaterals. Portal vein thrombosis may be classified based on the duration of symptoms 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: Defined as duration of symptoms <60 days and absence of portal carvernoma and portal hypertension
- Chronic portal vein thrombosis: Defined as duration of symptoms >60 days and/or presence of portal carvernoma and portal hypertension
