  • Title: The probability of closure in aortocoronary vein bypass grafts.
    Author: Rimm AA, Blumlein S, Braboriak JJ, Anderson AJ, Walker JA, Johnson WD.
    Journal: JAMA; 1976 Dec 06; 236(23):2637-40. PubMed ID: 1086909.
    Abstract:
    A study of 540 patients who had the aortocoronary vein bypass operation (from several transplant teams) showed that grafts within a patient closed independently of one another during the first-two year postoperative period. For patients with a single vein graft, there was a 23% chance of closure during the first two year postoperative period. The chance that all grafts would close during this period for patients with two grafts was 5%, and it was 1% for patients with three grafts. The knowledge of these closure probabilities may be used by the surgeon when planning the optimal surgical maneuver.
