Overview
Portal triaditis refers to inflammation affecting the structures within the portal triad, including the bile ducts, hepatic artery, and portal vein, often seen in the context of non-cirrhotic portal hypertension 12.Diagnosis
Key Diagnostic Criteria: Presence of portal vein thrombosis, ectopic varices, and non-cirrhotic portal hypertension 1.
Recommended Tests: Doppler ultrasonography to assess portal vein thrombosis and varices 1.
Clinical Signs: Hypotension, hematemesis, and melena may indicate active bleeding 1.
Unique Findings: Cruveilhier-Baumgarten venous hum, indicative of portal vein hypertension, may be observed 4.Management
First-Line Treatments: Cyanoacrylate injection for managing ectopic varices 1.
Adjunctive Treatments: Management of underlying causes such as portal vein thrombosis 1.
Monitoring: Long-term follow-up to assess for complications 1.Special Populations
Comorbidities: Hypoxaemia and digital clubbing can occur in non-cirrhotic portal hypertension, requiring pulmonary function assessment 2.Key Recommendations
Cyanoacrylate injection is effective for managing ectopic varices in non-cirrhotic portal hypertension (Evidence: Strong 1).
Doppler ultrasonography should be utilized for diagnosing portal vein thrombosis and identifying ectopic varices 1.
Patients with non-cirrhotic portal hypertension should be monitored for hypoxaemia and intrapulmonary shunting, particularly if presenting with digital clubbing 2 (Evidence: Moderate).
The Cruveilhier-Baumgarten venous hum can be a diagnostic marker for portal vein hypertension, distinguishing it from normal variants 4 (Evidence: Expert opinion).References
