Ligation of the patent ductus. Technical considerations at different ages
Insights
This study reviewed 185 patients treated for patent ductus arteriosus over 10 years. Double ligation is the preferred surgical method for most cases, with special techniques for complex cases.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Neonatology
Background:
- Patent ductus arteriosus (PDA) is a common congenital heart defect.
- PDA can lead to significant complications, especially in premature infants and neonates.
- Surgical intervention is sometimes necessary for PDA management.
Purpose of the Study:
- To analyze the outcomes of surgical patent ductus arteriosus obliteration over a decade.
- To evaluate different surgical techniques based on patient age and duct characteristics.
- To identify the most effective and safest surgical approach for PDA.
Main Methods:
- Retrospective review of 185 patients undergoing PDA treatment over 10 years.
- Categorization of patients by age (neonates, children, adults) and clinical presentation.
- Analysis of surgical techniques employed, including double ligation and specialized methods.
Main Results:
- 185 patients treated for PDA, including premature infants with respiratory distress syndrome.
- 35 neonates underwent duct obliteration for intractable heart failure.
- Adult patients showed a higher incidence of calcification/aneurysm requiring complex procedures.
Conclusions:
- Double ligation is a safe, simple, and quick technique for general PDA obliteration.
- Specialized surgical techniques are crucial for managing complex PDA anatomies.
- Surgical outcomes vary based on patient age and ductal pathology.
Abstract:
Over a 10 year period, 185 patients have been treated for patent ductus, including nine premature infants with a respiratory distress syndrome. Thirty-five other infants have had duct obliteration during the neonatal period, the incidation for surgery being intractable heart failure. Six of 18 adults had calcification or aneurysm in the duct region. three of these required extracorporeal circulation for duct control and closure. The remaining patients were from 1 to 18 years of age and underwent elective duct obliteration. Double ligation of the duct is regarded as the simplest, safest, and quickest technique generally applicable. Special techniques are required for fragile, broad, calcified, hypertensive, and conical ducts.
