Result of surgical treatments in patients with coronary-arterial obstructive disease after Kawasaki disease.
OBJECTIVE
To determine the efficacy of coronary artery bypass grafting (CABG) in young patients with coronary-arterial obstructive disease subsequent to Kawasaki disease.


METHODS
CABG was employed in 100 patients. Age at operation ranged from 1 to 23 years at a mean of 10+/-5 years. The number of bypass grafts placed was 1-5/patient (a mean of 1.7+/-0.8). The left internal-thoracic artery (ITA) was used as a graft in 99 patients; the right internal thoracic artery in 39, the gastroepiploic artery in nine and the saphenous vein in 21.


RESULTS
All patients survived the procedures. In the follow-up of 6.7+/-4.5 years, two patients died, one because of a traffic accident and the other due to sudden death. Considerable myocardial ischemia recurred postoperatively in 15, because of either obstruction of the bypass grafts or progression of other coronary-arterial obstructions. Of these, symptoms spontaneously regressed without interventional procedures in four, reoperation was indicated in four and catheter intervention was efficiently carried out in the remaining seven. Another two patients had episodes of critical ventricular arrhythmia; one of them with severe left ventricular dysfunction subsequently underwent cardiac transplantation. The patency rates of the arterial grafts were 94, 82 and 78% at 1, 5 and 10 years, respectively, and this was higher than that of the venous grafts (82, 63 and 36%, respectively). Strenuous exercise is currently prohibited in 15 patients, while the remaining 83 patients are doing well with no obvious restriction in their daily lives.


CONCLUSIONS
Collaborating with catheter interventions, CABG using the arterial grafts can provide attractive results in patients with obstructive coronary arteries associated with Kawasaki disease.
