[Significance of greater omentum anatomic structure]

The examination of the greater omentum was performed in 102 cadavers. Most frequently the quadrangular shape of omentum was found, less frequently--triangular and appendicular shape. The anterior duplicature of the omentum receives blood supply from the right gastro-omental artery, that often has 5 omental branches. The posterior duplicature is blood supplied by spleno-omental artery, that creates the inferior arterial arch. The methods of lengthening of omentum are worked out. Satisfactory filling of the created omental flaps was proved by arteriography.
