[Iatrogenic celiac-mesenteric arteriovenous fistulae; with reference to a new case of postgastrectomy arteriovenous fistula].

The authors report a rare case of iatrogenous arteriovenous fistula between left gastric artery and vein, arising after gastric resection. The observation caused a reviewing of the literature (19 cases published, of which only one between left gastric artery and vein) and some remarks about the physiopathology, pathological anatomy, clinics and treatment of such rare diseases. The authors, in their conclusions, emphasize that such arteriovenous fistulas can remain asymptomatic for a long time; they, moreover, with evident effects on the liver physiology, can progressively cause a serious state of portal hypertension, in the genesis of which the time-factor plays a primary role.
