RESUMEN
Visceral artery aneurysms are rare and occur only in 0.01-0.2% of people. According to various authors, incidence of aneurysm rupture is 10-20% with mortality rate of 20-70% depending on localization and dimensions. One of the causes of visceral artery aneurysms, in particular common hepatic artery aneurysm, is chronic pancreatitis. Incidence of this complication is 2-10%. The first clinical manifestation is often hemorrhagic shock following false aneurysm rupture and bleeding into abdominal cavity, gastrointestinal tract or retroperitoneal space. Common hepatic artery aneurysm is complicated by bleeding in 35% of cases, and mortality may be up to 75%. Treatment of visceral artery aneurysm following chronic pancreatitis and post-necrotic parapancreatic cyst includes several stages. Endovascular methods are the first stage of treatment. The second stage is elimination of the cause of visceral artery false aneurysm (surgery for chronic pancreatitis). We present 3 patients with visceral artery aneurysms and chronic pancreatitis.
