  • Title: Free internal mammary artery graft. An improved surgical technique.
    Author: Schimert G, Vidne BA, Lee AB.
    Journal: Ann Thorac Surg; 1975 Apr; 19(4):474-7. PubMed ID: 1122167.
    Abstract:
    An improved method of free internal mammary artery (IMA)-to-ascending aorta anastomosis for cornoary bypass is described. We interposed a small patch of vein with a suitable side-branch or brancyes in connecting the proximal end of a detached IMA or radial artery. Thirty-four free IMA-to-coronary artery bypasses were performed in 25 patients; 16 right IMA, 14 left IMA, and 4 radial arteries were used. Cornoary angiographic follow-up studies performed in all patients between two weeks and six months after operation proved that all grafts were patent and showing a larger lumen than is usually seen in undetached IMA grafts. Concomitantly marked relief of anginal pain was noted in all patients. Oour experience with this technique is very encouraging. All patients are being followed to evaluate long-term graft patency.
