[Revascularisation of the arteries of the digestive tract by retrosternal bypass from the left subclavian artery (author's transl)].

This technique of revascularisation of the digestive arteries is suggested when the infrarenal aorta cannot be used. The hepatic artery is reimplanted in the coeliac region. The vein graft is passed in the root of the transverse mesocolon and anastomosed with the superior mesenteric artery. The subclavian artery, frequently used in the revascularisation of the neck vessels, was felt to be preferable to the axillary artery. Passage of the graft retrosternally avoids any kinking or compression in the abdominal wall. The patient's own saphenous vein is the most suitable material. If this is not possible, a varicosity preserved by cold was felt to be preferable to a dacron tube.
