Insights

The Fontan procedure improves survival for single-ventricle patients into adulthood. Radiologists must recognize Fontan-associated liver disease and other abdominal issues like nodules, tumors, and enteropathy on imaging.

Area of Science:

  • Cardiology
  • Radiology
  • Hepatology

Background:

  • The Fontan procedure enhances survival for pediatric patients with functional single ventricles into adulthood.
  • Fontan circuit physiology elevates systemic venous pressure, potentially causing long-term multi-system organ failure.
  • Fontan-associated liver disease (FALD) is a significant complication, progressing to cirrhosis and portal hypertension.

Purpose of the Study:

  • To highlight common abdominal abnormalities in post-Fontan patients.
  • To familiarize radiologists with imaging findings in Fontan-associated liver disease (FALD).
  • To emphasize the importance of recognizing conditions like focal nodular hyperplasia-like nodules, hepatocellular carcinoma, protein-losing enteropathy, and pheochromocytoma/paraganglioma.

Main Methods:

  • Review of imaging findings in post-Fontan patients.
  • Correlation of imaging findings with clinical outcomes.
  • Emphasis on cross-sectional imaging modalities.

Main Results:

  • Focal nodular hyperplasia-like nodules are common in FALD.
  • Hepatocellular carcinoma infrequently develops in FALD.
  • Other potential abdominal abnormalities include protein-losing enteropathy and pheochromocytoma/paraganglioma.

Conclusions:

  • The Fontan procedure has improved long-term survival.
  • Radiologists need to be aware of unique imaging features of FALD.
  • Early recognition of associated abdominal conditions is crucial for patient management.

Finding the Center of Gravity01:03

Finding the Center of Gravity

The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...

Abdominal Aorta01:25

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Coronary Circulation01:21

Coronary Circulation

The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...
