[Results of palliative operations in infants with pseudotruncus arteriosus (author's transl)]
Insights
Palliative surgery for pulmonary atresia with VSD improves oxygen saturation and promotes growth. Survivors experienced significant improvements, with no late deaths, highlighting the procedure's long-term benefits.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease Surgery
- Thoracic Surgery
Background:
- Pulmonary atresia with ventricular septal defect (VSD) is a severe congenital heart defect.
- Palliative procedures aim to improve systemic oxygenation, facilitate pulmonary artery growth, and support overall development in affected infants.
Purpose of the Study:
- To evaluate the effectiveness of palliative surgical procedures in infants and young children with pulmonary atresia and VSD.
- To assess outcomes including arterial oxygen saturation, growth, pulmonary artery dilatation, and operative mortality.
Main Methods:
- A cohort of 33 severely symptomatic patients (5 days to 24 months) underwent palliative shunts.
- Procedures included ascending aorta-right pulmonary artery shunts (intrapericardial and extrapericardial) and Blalock shunts.
- Waterston shunts with cardiopulmonary bypass were used in two cases with absent left pulmonary artery.
Main Results:
- The operative mortality rate was 20%.
- Two patients required additional shunts for persistent cyanosis.
- All survivors demonstrated improved arterial oxygen saturation, enhanced growth and development, and maintained these benefits during a mean follow-up of 23 months.
- No late deaths were recorded.
Conclusions:
- Palliative surgical interventions for pulmonary atresia with VSD can effectively improve patient outcomes.
- These procedures facilitate crucial physiological improvements and support long-term development in survivors.
- Despite operative risks, the long-term results suggest significant benefits for carefully selected patients.
Abstract:
A palliative procedure in patients with pulmonary atresia with VSD should improve arterial oxygen saturation, allow growth and development, and promotes a uniform dilatation of the pulmonary arteries. Thirty-three severely symptomatic patients, ranging from 5 days to 24 mths of age and from 2,4 to 11 kg of weight underwent a variety of palliative operations, including the ascending aorta-right pulmonary artery shunt (intrapericardial: 15 cases; extrapericardial: 14 cases), the Blalock shunt (4 cases). In two cases, both with absence of the left pulmonary artery, a Waterston shunt was performed using cardiopulmonary by-pass. The operative mortality was 20%. In two patients an additional shunt procedure was deemed necessary due to persistent cyanosis. All the survivors improved in terms of arterial oxygen saturation, growth and development. There were no late deaths (mean follow-up: 23 months).
