Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug binding...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...

Transradial Access Chemoembolization for Hepatocellular Carcinoma Patients

Published on: September 20, 2020

Transarterial chemoembolization complicated by deteriorating hepatic function.

    Summary
    This summary is machine-generated.

    Chemoembolization can worsen liver function in up to 58% of patients, with a small percentage experiencing severe liver failure. Child-Pugh status is a key predictor of hepatic complications following this cancer treatment.

    Area of Science:

    • Hepatology
    • Interventional Radiology
    • Oncology

    Background:

    • Chemoembolization is a common cancer treatment.
    • Hepatic dysfunction is a known complication of chemoembolization.
    • While often transient, severe liver failure and death can occur.

    Purpose of the Study:

    • To review the incidence and risk factors for hepatic dysfunction after chemoembolization.
    • To highlight the prognostic significance of Child-Pugh status.

    Main Methods:

    • Review of existing literature on chemoembolization and hepatic complications.
    • Analysis of patient factors associated with increased risk of liver failure.

    Main Results:

    • Hepatic function worsens in up to 58% of patients post-chemoembolization.
    • Most patients recover within 3-4 weeks.
    • Fulminant liver failure and death occur in approximately 2-10% of cases.
    • Risk factors include poor performance status, portal vein obstruction, biliary obstruction, extensive tumor burden, and Child-Pugh B or C status.
    • Child-Pugh status is the most accurate predictor of hepatic failure risk.

    Conclusions:

    • Chemoembolization carries a significant risk of hepatic dysfunction.
    • Identifying high-risk patients, particularly those with advanced liver disease (Child-Pugh B or C), is crucial for management.
    • Supportive care is the primary treatment for hepatic failure, unless the patient is a liver transplant candidate.
