Massive postoperative hemorrhage from hepatic artery erosion

A 66-year-old male patient who had undergone repeated operations for peptic ulcer disease involving the right upper abdominal quadrant, developed cholecystitis with calculous obstruction of the common bile duct. The gallbladder was removed. Later, an operation was performed for removal of a residual stone from the common duct. At this time an anomalous arterial structure was noted about the duct. Hemorrhage occurred ten days postoperatively, and the anomalous hepatic artery was found to be eroded. The bleeding was controlled. During the succeeding two weeks there were four episodes of bleeding (involving erosion of the hepatic artery and adjacent tissues), three of which were controlled. The fourth episode ended in the death of the patient from exsanguination secondary to bleeding from stress ulcers in the gastric remnant. At no time did the laboratory data unequivocally indicate an abnormality of blood coagulation. Erosion of the anomalous cystic artery apparently precipitated the fatal chain of events.
