[Results of the chronic compression of visceral arteries in animal experiments].

Occlusions of different visceral arteries were imitated by progressive swelling substance constriction in 30 mongrel dogs. The variants of the developed collateral circulation could be proved by the postoperative angiographies. There is given reference to the importance of the connections of the visceral vascular system among one another and for the abdominal surgery of the human. Evidence is given that occlusions of the celiac artery and of the superior mesenteric artery are compensable only with the formation of large collateral vascular systems. But on certain circulation conditions the inferior mesenteric artery has a great significance too.
