Abstract:
Objective To investigate the feasibihty and superiority of transthoracic echocardiography(TTE)guided transcatheter occlusion for patent ductus arteriosus (PDA).Methods Totally 58 patients with simple funnel shape(Type A) PDA were studied retrospectively,and they were divided into angiography group(n =21) and echocardiography group(n =37).The angiography group received traditional transcatheter occlusion technique,and the echocardiography group received TTE guided transcatheter occlusion of PDA.An observation for the effect was taken post operatively,as well as for the comparison between the 2 groups in the aspects of the operation duration,the time of X-ray exposure,the radiation dose,the length of hospital stay and the expense of medication.Results Successful occlusion was performed in all patients.Both of the TTE and angiogram group showed good position of the occlusion devices.Moreover,the velocities of blood flow in left pulmonary artery and the descending aorta were in a normal range.Compared with angiography group,echocardiography group experienced shorter operation duration (P ＜ 0.05),shorter X-ray exposure time (P ＜ 0.05),lower radiation dose,fewer days of hospital stay (P ＜ 0.05) and less expense of the medication (P ＜ 0.05).Conclusions TTE-guided transcatheter occlusion for simple funnel shape PDA (Type A) is a simplified occlusion method,which is effective and preferential treatment to the method of traditional angiography guidance in clinical trials.
