Abstract:
Objective:To summarize the characteristics of hemodynamically significant patent ductus arteriosus (hsPDA) in very low birth weight (VLBW) preterm infants and evaluate the efficacy and safety of transcatheter PDA closure (TCPC).Methods:This was a retrospective study including five VLBW preterm infants who were diagnosed with hsPDA by echocardiography at Women and Children's Hospital, Qingdao University from January to December 2024 and underwent transcatheter closure after pharmacological therapy failure. Follow-up assessments were conducted at 6 months after operation to evaluate PDA closure status, survival outcomes, and the occurrence of complications. Descriptive statistical analysis was used to summarize the demographic characteristics and clinical data.Results:The cohort comprised three males and two females. The median gestational age was 28 (24-29) weeks, and the median birth weight was 1 000 (670-1 220) g. The median age and birth weight at surgery were 25 (13-36) d and 1 200 (810-1 400) g, respectively. The PDA diameter was 3.8 (2.3-4.1) mm. PDA closure was successfully achieved in all five infants using the Amplatzer Piccolo? occlude, with no major procedure-related complications. All patients were weaned from mechanical ventilation and discharged. At 6-month follow-up, all five infants survived with no residual shunt, left pulmonary artery stenosis, or aortic coarctation on echocardiography.Conclusions:TCPC is feasible and safe for VLBW preterm infants when pharmacological therapy is ineffective or contraindicated. Larger cohorts and extended follow-up are needed to assess long-term outcomes and potential complications.
