Resumen

Objetive. Percutaneous occlusion of patent ductus arteriosus (PDA) has classically been performed entirely by fluoroscopy, however in recent years, transthoracic echocardiography (TE) has been used as an aid to fluoroscopy or entirely by echocardiography, which avoids access of femoral artery, use of contrast and decrease in time and dose of radiation exposure. The objective of this study was to evaluate the success rate with the use of TE in percutaneous PDA closure. Material andmethod. Descriptive, comparative, retrospective study between patients in whom PDA closure was performed with fluoroscopy plus angiography (group 1) and fluoroscopy plus ET (group 2), between January 2018 and December 2022. The data were obtained from the clinical history electronic and procedure report. Results. One hundred eight patients were analyzed, fluoroscopy group (n: 57) and TE (n: 51). The success rate in PDA occlusion using TE was 100% and 98% for the fluoroscopy group, with no statistically significant difference The average age of group 2 was 2.9 years, while the average age of group 1 was 5 years (p=0.001), the average fluoroscopy time in group 1 was 16.9 min and 4.71 min in group 2 (p < 0.001); the fluoroscopy dose in group 1 was 68.98 mGy and 5.17 mGy in group 2 (p<0.001). Krichenko, but without significant difference in both groups. Conclusions. The success rate of percutaneous PDA closure using echocardiography and fluoroscopy is appropiate, with a success rate similar to the classic technique. In addition, it makes it possible to reduce the dose and time of fluoroscopy, avoid the use of contrast, and access the femoral artery.
