Air Embolism after Endoscopic Retrograde Cholangiopancreatography in a Patient with Budd Chiari Syndrome

Abstract

Endoscopic retrograde cholangiopancreatography is a procedure commonly used for the diagnosis and treatment of various pancreatic and biliary diseases. Air embolism is a rare complication, which may be associated with this procedure. This condition can be manifested as cardiopulmonary instability and/or neurological symptoms. Known risk factors include: sphincterotomy; application of air with high intramural pressure; anatomic abnormalities; and chronic hepatobiliary inflammation. It is important for the health-care staff, including anesthesiologists, interventional gastroenterologists, and critical care specialists, amongst others, to promptly recognize air embolism and to initiate therapy in a timely fashion, thus preventing potentially fatal outcomes. We submit a brief review of the literature and a case report of air embolism which occurred in the immediate postoperative stage of an endoscopic retrograde cholangiopancreatography, performed in a woman with a history of liver transplantation due to Budd Chiari syndrome and biliary stricture.
