abstract: The Authors present a case report of a spontaneous ruptured aneurysm of the superior pancreaticoduodenal artery (retropancreatic arterial arch), leading to a massive retroperitoneal hemorrhage with very severe hemorrhagic shock. They point out the rarity of such instances and explain some of the etiopathogenic, clinical and therapeutic aspects of this type of hemorrhagic pathology.
