An unexpected complication: Air embolism during contrast-enhanced computed tomography

Area of Science:

• Medical Imaging
• Cardiovascular Complications
• Radiology

Background:

• Air embolism is a known iatrogenic complication arising from procedures involving vascular access.
• It can manifest in either venous or arterial systems, with clinical presentation dependent on the entry point.
• Contrast-enhanced imaging procedures carry a risk of inducing air embolism.

Observation:

• A 40-year-old female developed symptoms of dyspnea and chest pain.
• These symptoms emerged shortly after undergoing contrast-enhanced chest computed tomography (CT) imaging.
• The patient was diagnosed with a venous air embolism in the pulmonary artery.

Findings:

• The venous air embolism was identified as a direct consequence of contrast agent injection during the CT scan.
• The patient experienced acute respiratory distress and thoracic discomfort.
• The condition was successfully managed with appropriate medical intervention.

Implications:

• This case highlights the importance of recognizing venous air embolism as a potential complication of contrast-enhanced CT.
• Early diagnosis and prompt management are crucial for mitigating patient morbidity and mortality.
• Awareness among healthcare professionals regarding this iatrogenic risk is essential for patient safety in diagnostic imaging.
