ABSTRACT

The paper describes the occurrence of a rare complication – portal and systemic venous air embolism – after endoscopic retrograde cholangiopancreatography, related to the endoscopic procedure. It can be associated with the more frequently encountered post-endoscopic retrograde cholangiopancreatography complications pancreatitis or cholangitis. However, it can also be noted with perforation. The presented case suggests that in the clinical context an early abdominal ultrasound examination confirming hepatic portal venous gas and/or systemic venous air embolism could be useful for the diagnosis of post-endoscopic retrograde cholangiopancreatography retroduodenal perforation, and thus highlights the need for a high index of suspicion should this occurrence be noted post-procedurally, in order to ensure the best care of patients.

Key words: intrahepatic portal venous gas; venous embolism; ERCP; retroduodenal perforation; retropneumoperitoneum
