Mini-incision Transthoracic Occlusion for PDA in Adults / 中国微创外科杂志

ABSTRACT

Objective To evaluate the efficacy and safety of mini-incision transthoracic occlusion for patent ductus arteriosus(PDA)in adults.Methods From November 2005 to May 2007,10 adult patients(occlusion group)received mini-incision transthoracic occlusion of PDA under the guidance of transesophageal ultrasonography in our hospital.A 3-to 5-cm incision was made at the second intercostal space adjacent to the left sternum to expose the pulmonary aorta.Afterwards,a catheter was introduced into the pulnonary artery,and then delivered into the aorta via the PDA under the guidance of ultrosonograohpy.An occluder of 4 to 6 mm larger than the PDA in diameter was then released to engage on the defect.Twenty patients who recieved on-pump surgery were set as a control group.Results Compared with the control,patients in the occlusion group had a smaller incision [(3.6?1.6)cm vs(25.3?5.4)cm,t'=-16.575,P
