He underwent an abdominal CT scan which showed a moderate-sized peripancreatic hematoma and a focal interruption of the proximal common hepatic artery without extravasation. He was transferred to our center and arrived in stable condition. Magnetic resonance angiography (MRA) and cholangiopancreatography (MRCP) was obtained and it redemonstrated segmental occlusion of the proximal common hepatic artery with collateral flow from the gastroduodenal artery. There was no evidence of a pancreatic injury (figure 1A,B). One week later, a surveillance abdominal computerized tomography angiography (CTA) demonstrated interval development of a 3.2×2.2 cm common hepatic artery pseudoaneurysm just distal to its takeoff from the celiac artery (figure 2). Immediately after CT, he became unresponsive with a systolic blood pressure of 60 mm Hg.Figure 1 (A,B) Coronal and axial slices of the MRA of the common hepatic artery one day after injury.Figure 2 Axial slice of the CTA abdomen of the ruptured hepatic artery pseudoaneurysm.Take to the operating room (OR) immediately for definitive vascular controlTake to interventional radiology (IR) for angioembolization of … ER -
