Superior mesenteric artery stent-graft placement in a patient with pseudoaneurysm developing from a pancreatic pseudocyst.

Pseudoaneurysm is a relatively rare but serious complication of pancreatitis which is often fatal. We report successful stent-graft placement in the superior mesenteric artery in a 45-year-old man with a pancreatic pseudocyst that grew during therapy for chronic pancreatitis and developed into a pseudoaneurysm. After a stent graft was inserted in the superior mesenteric artery, the pseudoaneurysm disappeared and no further complications developed. Stentgraft placement was considered to be a useful therapy for pseudoaneurysms in the superior mesenteric arterial region.
