Core Tip
Core tip: Portal hypertensive vasculopathy is well-investigated in cirrhotics. Raised portal pressure and hyperdynamic circulation are thought to be the underlying cause. Pathological changes in the splenic vein are similar in cirrhotic and non-cirrhotic portal hypertension (NCPH). They are not primarily due to venous degenerative changes, and are similar to those observed in the pulmonary vasculature in pulmonary hypertension. Portal hypertension in NCPH should be viewed as a systemic and pulmonary hypertension equivalent in the gastrointestinal tract. We show that these pathological venous changes in NCPH are observed in a greater proportion of patients in the delayed presentation group (P < 0.003). Interventions to reduce portal pressure should therefore be initiated at diagnosis of NCPH. Damage to the vasculature starts early and can be prevented from progressing to venous thrombosis and its sequelae if early surgical intervention is initiated to reduce portal pressure.
