[Complex coronary reconstructions using the internal mammary artery. Technique of surgical angioplasty, preliminary results].
A technique of coronary surgical angioplasty is described. The long arteriotomy of the coronary artery over the stenosis is closed with the Internal Thoracic Artery (ITA) giving an enlargement patch effect. The majority of the atheromatous plaque is excluded from the lumen of the anastomosis and placed outside the suture line. The origin of the collateral arteries is preserved in the vascular lumen. The remodeled coronary artery is composed of a small gutter of native coronary artery and the whole surface of the ITA wall. In some cases, it is useful to associate a limited endarterectomy with the angioplasty. 66 surgical angioplasties have been performed in extensive coronary disease. Operative mortality was 5.4% with a myocardial infarction rate of 5.4%.
