title: [The early angiographic follow-up of myocardial revascularization in a minithoracotomy: the results of the first 100 consecutive cases].
abstract: The use of the left internal thoracic artery anastomized to the left anterior descending coronary artery via a small left thoracotomy to revascularize the anterior wall of the left ventricle has gained wide acceptance since its introduction into clinical practice a few years ago. A mandatory, postoperative angiographic control was suggested in order to check the surgical results of this new method of revascularization. We herein analyze the results of the in-hospital angiographic control of a series of 100 consecutive patients who underwent minimally invasive coronary artery bypass. In all 100 patients the thoracic graft, the anastomosis and the target vessel were patent, with no anomalies in 90 subjects. In 4 patients, a sharp angulation of the thoracic artery in the last third before the anastomosis to the native vessel was observed; in 3 subjects, the arterial graft had been anastomized to a diseased tract of the target vessel and in 3 cases a significant stenosis of the target vessel beyond the anastomosis was documented; in 2 cases the persistence of a thoracic artery branch was discovered. Since 1) neither in-hospital total occlusion of the thoracic graft to the left anterior descending coronary artery via a small thoracotomy was documented nor a significant incidence of major anomalies was observed; 2) the anomalies documented seem to be clinically negligible and may regress in the midterm postoperative period; 3) Doppler flow analysis is able to detect not only the patency but also the presence of significant stenosis in the arterial graft; the in-hospital angiographic control of this surgical technique should be limited to patients with abnormal ultrasonic data or with reappearance of myocardial ischemia in the anterior wall of the left ventricle, thus not reducing the advantages in terms of speed and cost-control of this type of myocardial revascularization.
