title: [Late occlusion of the subclavian artery proximal to mammary bypass].
abstract: We report the cases of two patients with an occlusion of the left subclavian artery several years after left internal mammary bypass of the anterior interventricular artery. The effect on the myocardium was only apparent after scintigraphy in one case, and was clinical in the second with angina pain on exertion of the upper limb. Re-implantation of the subclavian artery in the common carotid relieved the signs of myocardial ischaemia. While the internal mammary artery is the conduit of choice for coronary revascularisation because it is not affected by atheromatous lesions, this does apply to the proximal subclavian artery. Stenosis or occlusion here can entail ischaemia in the revascularised myocardial territory. Regular clinical and ultrasound surveillance can detect these lesions.
