Overview
Chronic hepatic failure involves progressive deterioration of liver function over months to years, often leading to complications such as portal hypertension, coagulopathy, and hepatic encephalopathy. 1Diagnosis
Clinical Presentation: Symptoms may include jaundice, ascites, encephalopathy, and coagulopathy.
Laboratory Tests: Elevated liver enzymes, prolonged prothrombin time, and hypoalbuminemia.
Imaging: Ultrasound or CT scan to assess liver morphology and detect portosystemic shunts.
Portal Vein Imaging: MRI or CT portography for detailed shunt identification 1.Management
Supportive Care: Fluid management, nutritional support, and treatment of complications like ascites and encephalopathy.
Medications: Lactulose for hepatic encephalopathy, diuretics for ascites (e.g., spironolactone, furosemide).
Specific Interventions: For congenital portosystemic shunts, monitor for spontaneous closure, especially in cases with neonatal cholestasis 1.Special Populations
Pediatrics: Neonatal cholestasis predicts higher likelihood of spontaneous closure of intrahepatic shunts before 24 months 1.
Comorbidities: Patent ductus venosus shunts rarely close spontaneously, requiring closer monitoring and potential intervention 1.Key Recommendations
Monitor neonates with congenital portosystemic shunts presenting with cholestasis closely, as they have a higher likelihood of spontaneous shunt closure (Evidence: Moderate) 1.
Consider imaging studies such as MRI or CT portography for detailed assessment of portosystemic shunts in chronic hepatic failure patients (Evidence: Moderate) 1.
Implement supportive care measures including fluid management and nutritional support tailored to the patient's specific complications (Evidence: Expert opinion) 1.References
