Minithoracotomy for extrapleural closure of the patent ductus arteriosus (PDA) in seriously ill patients offers a fast and less invasive alternative to conventional transpleural ductal closure. This study reports the immediate postoperative clinical outcomes for 24 extrapleurally clipped premature infants presenting with congestive heart failure in high-risk comorbidity status between March 2007 and November 2010. The demographics, preoperative clinical characteristics, and postoperative outcomes of the patients, including echocardiographic assessments, were evaluated. No surgery-related mortalities occurred. Four mortalities occurred after surgery due to sepsis and bleeding diathesis. All 20 surviving patients exhibited normal left ventricular dimensions and systolic function in the immediate follow-up period. The study shows that extrapleural clip closure in seriously ill premature infants has an acceptable overall short-term mortality and complication rate with a high rate of ductal closure.
