BACKGROUND: Demonstrate the augmentation of flow of the internal mammary artery (IMA) after inflation of the graft with an atraumatic balloon catheter (Fogarty IMAG balloon catheter) before performing the anastomosis IMA-coronary artery, in coronary artery bypass operated patients. METHODS: In 1992 and 1993 a group of 87 coronary artery bypass patients underwent dilatation of the IMA with the Fogarty balloon catheter. The flow of the IMA was measured during 1 minute before and after balloon dilatation, prior to go on cardiopulmonary bypass. RESULTS: In all patients but one the flow increased after balloon dilatation. The mean free flow before dilatation was 52.8 ml/min (range 16-120 ml/min) and after balloon dilatation 122.6 ml/min (range 36-380 ml/min). The flow increased more than two folds which was of statistical significance (p<0.001). The hospital mortality was 6.8% (6 patients) not related with the mechanical manipulation of the arterial graft. CONCLUSIONS: Balloon dilatation of IMA is an alternative in cases in which the IMA graft presented with: 1) low free flow, 2) small size and 3) arterial spasm. The IMAG balloon catheter has to be properly adjusted and the shear force regulated at 30 grams.
