Imaging of abdominal complications following cardiac surgery.

Ten thousand seven hundred fifty-six patients underwent cardiac bypass surgery at the Mater Hospital national cardiac unit between September 1979 and April 1993. Of this group, 49 patients were identified who had developed postoperative gastrointestinal complications leading to 16 deaths. Twenty-five patients developed gastrointestinal hemorrhage, eight patients developed gallbladder disease, five patients developed phlegmonous pancreatitis, eight patients developed bowel perforations, and three patients developed intestinal pseudoobstruction. The particular radiological features that lead to diagnosis in each case are discussed and relevant literature is briefly reviewed.
