Management of Portal Hypertension and Variceal Bleeding

Portal hypertension, resulting from increased resistance to portal blood flow and augmented splanchnic inflow, underlies life-threatening complications such as gastro-oesophageal varices and variceal haemorrhage. Management strategies are stratified into primary prophylaxis to prevent the first bleed, secondary prophylaxis to avert rebleeding, and acute intervention for active haemorrhage. Non-selective beta-blockers reduce portal pressure by lowering cardiac output and inducing splanchnic vasoconstriction, whereas endoscopic variceal ligation achieves direct obliteration of high-risk varices. In acute bleeding episodes, combination therapy using vasoactive agents and urgent endoscopy has markedly improved short-term survival. For patients with recurrent or refractory bleeding, transjugular intrahepatic portosystemic shunt (TIPS) placement provides effective portal decompression, though careful patient selection is essential to minimise the risk of encephalopathy. Recent advances include the use of haemodynamic-guided therapy, refinements in stent design to balance patency and flow, and emerging pharmacotherapies targeting hepatic fibrogenesis and vascular tone. Integration of non-invasive diagnostics, prognostic models and multidisciplinary care pathways has harmonised clinical decision-making and enhanced patient outcomes. Globally, disparities in access to endoscopy and interventional radiology underscore the need for adaptable protocols that emphasise pharmacological prophylaxis, training in endoscopic techniques and resource-appropriate algorithms. The contemporary landscape reflects deepening insights into vascular pathobiology, interventional technology and personalised medicine, all aimed at reducing mortality from variceal haemorrhage.

Management of Portal Hypertension and Variceal Bleeding publication trend

The graph below shows the total number of articles in management of portal hypertension and variceal bleeding across all publications each year (not limited to Nature Index journals).

Technical terms

Portal hypertension: elevation of pressure within the portal venous system, usually arising from increased intrahepatic resistance and splanchnic vasodilatation.

Variceal haemorrhage: life-threatening bleeding from dilated gastro-oesophageal venous collaterals that form in response to portal hypertension.

Transjugular intrahepatic portosystemic shunt (TIPS): an image-guided endovascular procedure creating a channel between the portal and hepatic veins to decompress portal pressure.

Porto-sinusoidal vascular disorder (PSVD): a group of non-cirrhotic vascular liver diseases characterised by portal venule and sinusoidal histological lesions, with or without clinically evident portal hypertension.
