Aortic Injury and Hemopericardium: Key Findings and Evaluation
Journal of the Korean Society of Radiology
|August 8, 2026
Summary
CT angiography (CTA) is crucial for diagnosing life-threatening traumatic aortic injuries and hemopericardium. Key imaging findings and grading systems guide urgent management decisions in acute thoracic trauma care.
Area of Science:
- Emergency Medicine
- Radiology
- Cardiovascular Surgery
Background:
- Traumatic thoracic aortic injury and hemopericardium are critical, life-threatening conditions in acute trauma.
- CT angiography (CTA) is the primary imaging modality for evaluation, diagnosis, and treatment planning.
Purpose of the Study:
- To review imaging findings, grading systems, and management implications for traumatic aortic injury and hemopericardium.
- To highlight common diagnostic pitfalls and the importance of structured reporting.
Main Methods:
- Review of CTA findings in traumatic aortic injury, including intimal flaps, intramural hematomas, pseudoaneurysms, and contrast extravasation.
- Analysis of CT characteristics for traumatic hemopericardium, cardiac tamponade, and associated injuries.
- Discussion of common mimickers and artifacts.
Main Results:
- CTA findings are categorized using the Society for Vascular Surgery grading system for aortic injuries.
- CT features of hemopericardium and tamponade inform intervention urgency.
- Identification of pitfalls like ductus diverticulum and mediastinal hematoma is crucial for accuracy.
Conclusions:
- Accurate interpretation of CTA is essential for managing traumatic thoracic aortic injury and hemopericardium.
- Understanding grading systems, pitfalls, and structured reporting improves diagnostic accuracy and patient care.

01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:19Pericarditis II: Clinical Features and Diagnostic Tests
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
01:15Aortic Regurgitation I: Introduction
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

01:25Pericarditis IV: Nursing Management
Pericarditis, an inflammation of the pericardium, necessitates diligent nursing management to ensure effective patient care and recovery. The initial step in managing pericarditis is a comprehensive patient medical assessment.The patient reports chest pain aggravated by breathing, coughing, and swallowing, which worsens when lying supine. The pain often improves when sitting up and leaning forward. Additional symptoms may include fever, malaise, and, in severe cases, signs of heart failure.
