Abstract：Objective: Assessment of both transthoracic echocardiography(TTE) and X-ray measuring ductus arteriosus pre-occlusion and the occluders after operation, in order to direct choice of occluder. Methods: All 132 cases of patent ductus arteriosus(PDA) had been measured by TTE and X-ray before operation, and all the occluders had been measured after operation with the same ways. Comparing the best narrow diameter of PDA, the diameter of occluder’s waist with the size of the occluder. Evaluating correlation of the two methods, which TTE and X-ray measured pre-occlusion and after operation. Results: ①There was significant correlation about the best narrow diameter measure of PDA with TTE and X-ray before closure(r=0.82, P<0.05), and did so after closure(r=0.79, P<0.05). ②The equations of linear regression about the size of the occluder compared with the best narrow diameter of PDA pre-occlusion by TTE and X-ray: Y＝1.35X1＋2.20（t＝11.90, P<0.05）, Y=1.49X2＋2.66（t＝14.87, P<0.05）; the equations of linear regression about the size of the occluder compared with the diameter of the occluder’s waist after closure by TTE and X-ray: Y=0.92X3+4.01(t＝10.5, P<0.05), Y=1.30X4+2.02(t=15.08, P<0.05). Conclusion: Both TTE and X-ray played an important role in choosing occluder of PDA, but X-ray was superior to TTE.
