From 1992 to April, 1998, coronary bypass was performed on 3053 cases. Sequential İnternal thoracic artery grafting was used in 34 patients. Therc were 27 male, and 7 female patients; whose ages ranged from 40 to 78 (m: 59.3±9.4). Five patients underwent coronary bypass without cardiopulmonary bypass. Number of distal bypasses wcre between 2-6 (m: 4.1±1.1). Configuration of sequential İnternal thoracic artery was to left anterior descending artery - diagonal artery - right posterior descending artery - left anterior descending artery in 8 cases, and to proximal left anterior descending artery - distal left anterior descending artery in 25 cases. Aneurysmec- tomy in 2 cases, mitral valve replacement in l case, and ascending - descending aortic bypass due to coarctation in l case was performed as associated procedures.

In the early postoperative period, reoperation due to excessive bleeding vvas performed on 2 patients, and there was a case of cerebrovascular accidtmt in 1 patient. Perioperative myocardial infarction and mortality did not occur. Ali of the cases have been followed, and follow-up time ranged from 1 to 36 months (m: 11.7±10.6), 399 patient-months. Prema ture angina did not develop in any of the patients. Magnetic resonance imaging revealed a patent İnternal thoracic artery 2 months postoperatively in a patient who had been operated on for coronary artery disease associated with coarctation of the aorta, in another case, control coronary arteriogra- phy revealed a patent sequential İnternal thoracic artery 16 months postoperatively.

Use of sequential İnternal thoracic artery does not increase morbidity in the early postoperative period, and has long-term advantages.
