Sudden death due to ruptured pancreaticoduodenal artery aneurysm

Superior pancreaticoduodenal artery aneurysms are rare; their rupture often leads to sudden death. We report a case of a 59-year-old hypertensive man who died of a massive retroperitoneal hemorrhage following rupture of an aneurysm of the superior pancreaticoduodenal artery. We also discuss this unusual vascular lesion and review the pertinent literature.
