A 36-year-old woman diagnosed with complicated cholecystolithiasis underwent elective laparoscopic cholecystectomy (LC), then converted to open cholecystectomy because of a massive intraoperative bleeding. Hemostasis was performed with clipping and suturing the source of bleeding. In post-operative period, the patient suffered from persistent anemia associated with hemoperitoneum diagnosed through abdominal CT scanning, in absence of any sign of active bleeding. She died 16 days after the surgical procedure. Autopsy revealed the presence of 2 clips adjacent to the suture used for ligating the cystic artery and the presence of 3 surgical metal clips on the right hepatic artery, that should not be present in a routine cholecystectomy. The review of CT scans performed during the hospital stay revealed contrast extravasation from the right hepatic artery, near the 3 clips, allowing the post-mortem diagnosis of pseudoaneurysm (PA). The diagnosis of PA of right hepatic artery is typically made in living patients, through imaging, and autoptic identification is rarely obtained. The innovation of this report is to present an iconographic correlation between in vivo imaging and autopsy data, allowing for the tracing of the PA's origin to the wall weakening caused by the placement of 3 clips on the right hepatic artery, and having significant medico-legal implications.
