Dieulafoy disease: arteriographic findings and treatment.

Dieulafoy disease is an unusual cause of massive and frequently fatal gastrointestinal tract hemorrhage that results from the erosion of a submucosal artery. Although the lesion has been found throughout the gastrointestinal tract, it most commonly occurs in the proximal stomach. Nine patients with this condition have been treated at the authors' institution during the past 5 years. The bleeding lesion was located before surgery with selective visceral arteriography in three patients. Rapid extravasation was demonstrated from an eroded but otherwise normal-appearing artery in all three cases. Hemorrhage was controlled successfully in one patient with selective embolization of the involved left gastric artery branch. The remaining eight patients were treated with surgical ligation.
