Primary surgical closure should be considered in premature neonates with large patent ductus arteriosus

Area of Science:

• Neonatalogy
• Pediatric Surgery
• Cardiology

Background:

• Patent ductus arteriosus (PDA) is common in premature infants, with treatment options including medical and surgical approaches.
• The optimal management strategy for PDA in premature neonates remains a subject of debate.
• This study investigates the impact of surgical intervention on survival rates in premature infants weighing less than 1,500 g with PDA.

Purpose of the Study:

• To evaluate the efficacy of surgical intervention in improving survival outcomes for premature neonates with PDA.
• To compare the outcomes of medical management, delayed surgical treatment, and primary surgical treatment for PDA in low-birth-weight infants.

Main Methods:

• A cohort of 68 premature infants weighing less than 1,500 g with PDA was divided into three groups: medical management only, medical management followed by surgery, and primary surgical treatment.
• Data were collected from January 2008 to June 2011.
• Outcomes analyzed included mortality, need for surgery, mechanical ventilation duration, and incidence of bronchopulmonary dysplasia (BPD).

Main Results:

• Medical treatment failed in a high percentage (67.6%) of patients with large PDA (≥2 mm), with only 20.5% successfully managed medically.
• No mortality was associated with surgical procedures.
• Primary surgical closure (Group III) was associated with a significantly lower incidence of BPD (p=0.008), while delayed surgery (Group II) resulted in longer mechanical ventilation times (p=0.002).

Conclusions:

• Medical management of PDA exceeding 2.0 mm in infants <1,500 g has a high failure rate.
• Surgical closure after failed medical treatment is linked to increased mechanical ventilation duration and higher rates of BPD.
• Primary surgical closure for PDA >2.0 mm in premature infants <1,500 g should be considered to decrease mortality and long-term morbidities like BPD.
