Clinical Signs of Portal Hypertension
Portal hypertension is suggested by clinical collateral circulation, splenomegaly, ascites, or portosystemic encephalopathy in a patient with chronic liver disease. [1] Common bedside findings include gastroesophageal varices, peripheral edema, and physical stigmata of chronic liver disease that co-occur with portal hypertension. [1,2]
Gastroesophageal Variceal Findings
- Hematemesis from upper gastrointestinal bleeding consistent with esophageal or gastric varices is a key clinical manifestation of portal hypertension. [1,2]
- Melena can occur from variceal bleeding. [1]
- “Stigmata of chronic liver disease” in the setting of gastrointestinal bleeding support portal hypertension-related varices. [2]
Ascites and Peritoneal Findings
- Ascites is a major clinical sign of clinically significant portal hypertension. [1,3]
- Peripheral edema may be present in patients with decompensation due to portal hypertension and cirrhosis. [1,2]
Portosystemic Collateral Circulation
- Caput medusae is caused by prominent periumbilical collateral veins and is suggestive of portal hypertension. [1,2]
- Ectopic or abdominal wall collateral vessels can indicate portosystemic shunting. [2]
Splenomegaly and Hypersplenism
- Splenomegaly is a common physical finding due to portal-systemic congestion. [1,3]
- Hypersplenism can accompany splenic congestion and contributes to cytopenias in decompensated cirrhosis. [1]
Portosystemic Encephalopathy and Related Signs
- Portosystemic encephalopathy is a clinical manifestation that can occur in patients with portal hypertension and advanced liver disease. [1]
Stigmata of Chronic Liver Disease Associated With Portal Hypertension
- Jaundice, spider angiomas, palmar erythema, gynecomastia, testicular atrophy, Dupuytren contractures, parotid enlargement, and other chronic liver disease signs may coexist with portal hypertension. [2]
Clinical Sign Clusters Used in Practice
Portal hypertension is clinically suspected when chronic liver disease is accompanied by at least one of the following: [1]
- Collateral circulation.
- Splenomegaly.
- Ascites.
- Portosystemic encephalopathy.
