Insights
Budd-Chiari syndrome (BCS) involves liver vein obstruction. This review emphasizes the crucial role of imaging in diagnosing BCS, addressing a gap in the literature.
Area of Science:
- Radiology
- Hepatology
- Vascular Medicine
Background:
- Budd-Chiari syndrome (BCS) is hepatic venous outflow tract obstruction.
- It results from hepatic vein (HV) or inferior vena cava (IVC) involvement.
- Causes range from hypercoagulable states to malignancies, with 25% idiopathic.
Purpose of the Study:
- To highlight the importance of imaging modalities in diagnosing BCS.
- To address the lack of detailed imaging descriptions in existing BCS literature.
Main Methods:
- Review of existing literature on Budd-Chiari syndrome.
- Focus on diagnostic imaging features and modalities.
Main Results:
- Diagnosis relies on combined clinical and imaging findings.
- Various imaging modalities are essential for BCS diagnosis.
Conclusions:
- Imaging plays a critical role in the diagnosis of BCS.
- Further detailed descriptions of imaging manifestations are needed.
Abstract:
Budd-Chiari syndrome (BCS), also known as hepatic venous outflow tract obstruction includes a group of conditions characterized by obstruction to the outflow of blood from the liver secondary to involvement of one or more hepatic veins (HVs), inferior vena cava (IVC) or the right atrium. There are a number of conditions that lead to BCS-ranging from hypercoagulable states to malignancies. In up to 25% patients, no underlying disorder is identified. Diagnosis of BCS is based on a combination of clinical and imaging features. A major part of the literature in BCS has been devoted to interventions; however, a detailed description of various imaging manifestations of BCS is lacking. In this review, we highlight the importance of various imaging modalities in the diagnosis of BCS.
