Abstract
|
|
|
|
Iatrogenic air embolism is a rare and potentially fatal complication of gastrointestinal endoscopy. We present a 66-year-old male patient who developed cerebral arterial gas embolism shortly after therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for acute biliary pancreatitis, which is the first case reported in Hong Kong according to latest literature search. Some risk factors of iatrogenic air embolism in this patient include cholangitis with intraductal stones, sphincterotomy and bleeding at papillotomy site which required haemostasis with balloon tamponade. Early diagnosis and timely treatment with hyperbaric oxygen therapy resulted in full neurological recovery of our patient.
