Research on diagnosis and surgical treatment of congenital coronary artery fistula / 中国医师进修杂志

ABSTRACT

Objective To summarize and analyze clinical diagnosis and surgical treatment methods of 11 cases with congenital coronary arterial fistula (CCAF). Methods The clinical data of 11 patients who were definited by ultrasonic cardiogram, CT angiography (CTA) and coronary angiography were analyzed retrospectively. Four cases were simple CCAF, 7 cases coexisted with other heart abnormalities. Six cases were given surgical closure of fistula without cardiopulmonary bypass. One of the cases adopted coronary artery under the tangent cotton-padded mattress suture, and 4 cases fistula arterial were ligatured directly. Six cases were given surgical closure of fistula under cardiopulmonary bypass. The right coronary arterial was opened in three of the cases with right coronary artery aneurysm to close fistula. The chambers of heart in the others were opened to close fistula. Results All patients received surgical treatment successfully, and no death happened during the operation. The ultrasonic cardiography showed that all patients recovered well. Follow-up was conducted on 10 patients with the time period ranging from 3 months to 5 years. There was no death and no complication. Conclusions Combined application of ultrasonic cardiogram, coronary angiography and CTA increases the accuracy rate of diagnosis greatly and offers visual bases to formulate operation plan. Surgical operation is quite effective for congenital coronary arterial fistula after definite diagnosis. Operator should try to reserve the expanded coronary arterial, strengthen the anticoagulant after opeation to prevent thrombosis.
