Interruption of the aortic arch. Surgical considerations
The Journal of Thoracic and Cardiovascular Surgery
|August 1, 1976
Summary
Surgical outcomes for interruption of the aortic arch (IAA) showed a 60% mortality rate. Successful two-stage repair was achieved in one infant, while another survivor underwent total correction, highlighting improved survival with associated lesion repair.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Defects
Background:
- Interruption of the aortic arch (IAA) is a critical congenital heart defect.
- Surgical management of IAA presents significant challenges.
- Associated cardiac anomalies are common in IAA patients.
Purpose of the Study:
- To review surgical outcomes for interruption of the aortic arch (IAA).
- To evaluate different surgical strategies for IAA repair.
- To identify factors influencing survival rates in IAA patients.
Main Methods:
- Retrospective analysis of 5 patients with IAA operated between 1965 and 1975.
- Description of surgical techniques including two-stage repair and total correction.
- Comparison of outcomes with palliative versus corrective procedures.
Main Results:
- Overall mortality rate was 60% (3 out of 5 patients).
- Two patients survived: one infant with Type A IAA underwent successful two-stage repair, and a 3-year-old with Type B IAA had total correction.
- Improved survival was noted when associated lesions (VSD, PDA) were addressed concurrently.
Conclusions:
- Surgical repair of IAA has a high mortality rate.
- Staged or palliative procedures can be effective, particularly in infants.
- Total correction, when feasible, combined with management of associated defects, improves survival outcomes for interruption of the aortic arch.
