Abstract:
Objective The aim of this study was to explore the clinical value of dual-source CT(DSCT)in the diagnosis of coronary artery fistula(CAF)before and after surgery. Methods A retrospective analysis was performed in 15 cases of patients with CAF,11 cases of which was treated by surgery during extracorporeal circulation. Results CAF arose from right coronary artery in 8 cases and left coronary artery in 7 cases,with the latter including 3 cases of ramus nodi sinuatrialis fistula,2 cases of anterior descending branch fistula,and 2 cases of left circumflex fistula. CAF entered into right atrium(6 cases),right ventricle(5 cases),left ventricle(4 cases)and left atrium(1 case). There were dilatation of coronary artery in 8 cases,localized aneurysm in 4 cases,normal coronary artery in 3 cases,single fistula orifice in 11 cases,and multiple fistula orifice in 4 cases. 11 patients underwent surgery under cardiopulmonary bypass(CPB).The postoperative imaging revealed fistula has been sutured in 10 patients with no residual fistula,including fistula vascular ligation in 3 cases,the proximal imaging and distal occlusion in right coronary artery angioplasty in 1 case,and pseudo diverticulum in 2 cases. Conclusion DSCT examination has significant value in preoperative diagnosis and postoperative follow-up for CAF.
