Abstract
This study aimed to explore the efficacy of different surgical treatment for coronary artery lesions (CALs) caused by Kawasaki disease (KD) in children. We retrospectively analyzed the records of children with KD who presented with CALs to our hospital between 2015 and 2022. The patients were aged 126 ± 44.3 months (range: 84-180 months), and their body weight was 37.1 ± 18.6 kg (range: 17-60 kg). All patients were diagnosed with KD and were treated with standard medications. The patients had CALs for an average of 78 months (range: 24-156 months). All children underwent surgical treatment. In addition, one patient underwent cardiac defibrillator implantation, two underwent coronary artery bypass grafting (CABG), and one underwent heart bypass transplantation. The internal thoracic artery was used as the source of the left anterior descending branch bridge tube. The no-touch technique was used to obtain the free right thigh great saphenous vein as the bridge tube of the right coronary artery. All four patients had good postoperative recovery and the cardiac ultrasonography showed improved cardiac function and smooth coronary artery blood flow. The preoperative left ventricular ejection fraction was 44 ± 23.4%, which was significantly improved to 61.4 ± 14.0% postoperatively (p > .05). The preoperative left ventricle size was 5.6 ± 1.6 cm, which was significantly improved to 4.0 ± 0.6 cm postoperatively (p > .05). The two patients who underwent CABG received oral aspirin (5 mg/kg) and clopidogrel (1 mg/kg) antiplatelet therapy. The patients received oral tacrolimus antirejection drugs after the heart transplantation. The postoperative cardiac function was above grade II, and there were no symptoms of cardiac insufficiency, such as syncope, chest tightness, and orthopnea. Patients with CALs due to KD should be treated in a timely manner. The selection of an appropriate surgical treatment leads to prolonged survival and improved quality of life of patients.
