AbstractDigestive endoscopic procedures have become increasingly common diagnostic and therapeutic procedures in hospitals. Generally they are safe procedures and complications, though infrequent, can occur and are potentially lethal. As the number of procedures performed increases, the complications arising are likely to become more frequent, so it is advisable to bear this in mind when establishing early diagnosis and treatment. Cerebral air embolism is a rare complication after a digestive endoscopic procedure, although in the case of endoscopic retrograde cholangiopancreatography (ERCP), may be as high as 10%. In such cases there are usually local circumstances exist favoring the entry of air into the bloodstream, and in some cases it is the presence of a patent foramen ovale that favors the passage of air into the arterial system. The clinical signs and symptoms will depend on the speed and volume of the air infused and on the territory affected, and in some cases the consequences may be fatal.Copyright © 2016 Elsevier Inc.
