Gastroduodenal artery pseudoaneurism simulating pancreatic neoplasic injury: case report and literature review. gastroduodenal artery pseudoaneurism: a secondary vascular complication to chronic pancreatitis.

Visceral artery aneurysms are uncommon conditions and, depending on the mechanism of formation and etiological factors, they can be divided into pseudoaneurysms and true aneurysms. Pseudoaneurysms are mainly caused by pancreatic inflammatory and infectious processes (pancreatitis), which allow the dissemination of proteolytic enzymes that promote vessel wall weakening and erosion. A 44-year-old male patient was admitted to our hospital with abdominal complaints. He underwent ultrasound and computed tomography that diagnosed vascular pseudoaneurysm adjacent to the head of the pancreas and biliary tract. Endovascular technique has currently been the strategy of choice for the treatment of pseudoaneurysms, as it is a safe and effective method, less aggressive, generally as a shorter hospital stay.
