Background:
Endoscopic retrograde cholangiopancreatography (ERCP) is a key procedure for diagnosing and treating biliary and pancreatic disorders. Although effective, it carries risks, including rare but severe complications such as air embolism.
Case Summary:
We report a case of a 58-year-old man who developed extensive air embolism during ERCP. He previously underwent a Whipple procedure and experienced a sudden drop in vital signs and loss of consciousness. Immediate intervention with hyperbaric oxygen therapy and supportive care led to gradual recovery. Imaging confirmed widespread air embolism, which resolved with continued treatment.
Conclusion:
Air embolism is a rare, critical complication of ERCP, especially in patients with prior surgery such as pancreaticoduodenectomy. Early detection and prompt treatment, including hyperbaric oxygen therapy, are crucial for favorable outcomes.
