PurposeWe report 12 patients with visceral PA following pancreato-biliary and hepatic surgery.ResultsSeven patients (7/11, 63 %) had developed postoperative complications from their original procedure; that information was missing in one patient. Bleeding occurred in eight (three with hemoperitoneum two with haemobilia, and three with GI bleeding through a biliary-enteric anastomosis), three were asymptomatic, and the other one presented with abdominal pain. Eleven patients had an interventional radiology procedure performed (Five underwent angioembolization, a stent was placed in four, and two patients underwent both procedures). Complications related to the procedure developed in 6 (54.5 %) patients, and surgery was required in four of them.ConclusionPostoperative pseudoaneurysms (PA) of visceral arteries are rare and usually secondary to vascular injury after pancreato-biliary and liver surgery. They usually present with bleeding and nowadays most are amenable to initial control by interventional radiology.
