Cardiac Arrest From Sulfur Hexafluoride Contrast Anaphylaxis After Prior Perflutren Hypersensitivity

Key Points

• To highlight a case of anaphylaxis from sulfur hexafluoride lipid microspheres leading to cardiac arrest in a patient previously sensitized to perflutren.
• Case report detailing the occurrence of anaphylaxis after exposure to sulfur hexafluoride.
• Observation of patient history related to perflutren hypersensitivity.
• Evaluation of clinical response and resuscitation efforts following cardiac arrest.
• Documented case of cardiac arrest triggered by anaphylaxis after sulfur hexafluoride exposure.
• Cross-sensitization observed between sulfur hexafluoride and perflutren lipid microspheres.
• Emphasis on preparedness for resuscitation in patients with known hypersensitivity.
