Application of single venous approach under echocardiography without angiography in closure of Patent Ductus Arteriosus

Compared with the conventional arteriovenous approach, the single venous approach has the outstanding advantage of reducing vascular complications, contrast volume, radiation dose, and procedure time. Compared with the conventional arteriovenous approach, on the basis of obtaining the same efficacy, the PDA occlusion of the single venous approach under echocardiography without angiography has the outstanding advantages of simplified operation, less X-ray radiation, no contrast agent injury, short bed rest time, and fewer vascular complications. It is a green and safe surgical method worth promoting for PDA patients with suitable anatomical conditions.
