Anomalous systemic and pulmonary venous connections in conjunction with atriopulmonary anastomosis (Fontan-Kreutzer).
Insights
Complex congenital heart disease repair is challenging with anomalous venous connections. Successful surgical strategies, like extracardiac exclusion, improve outcomes for patients undergoing modified Fontan-Kreutzer procedures.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Anomalous systemic or pulmonary venous connections complicate complex cyanotic heart diseases.
- Atriopulmonary anastomotic procedures are often necessary for these conditions, posing challenges for venous pathway separation.
Purpose of the Study:
- To analyze the incidence and management of anomalous venous connections in patients undergoing modified Fontan-Kreutzer procedures.
- To evaluate surgical techniques for managing these anomalies and their impact on patient outcomes.
Main Methods:
- Retrospective review of 170 modified Fontan-Kreutzer procedures.
- Identification and classification of anomalous systemic and pulmonary venous connections.
- Analysis of surgical techniques employed and patient survival rates.
Main Results:
- Anomalous venous connections were present in 10% (17/170) of patients.
- Surgical repair achieved an 82.3% (14/17) survival rate.
- Extracardiac exclusion of left superior vena cava with left cavopulmonary shunt was more successful than intratrial baffles.
Conclusions:
- Managing anomalous venous connections in conjunction with modified Fontan-Kreutzer procedures requires individualized surgical planning.
- Detailed preoperative diagnosis is crucial for optimizing venous pathway reconstruction and patient outcomes.
Abstract:
Anomalous systemic or pulmonary venous connections can coexist with certain forms of complex cyanotic heart diseases that are reparable only by atriopulmonary anastomotic procedures, thus complicating the intraatrial separation of systemic and pulmonary venous pathways. Anomalous systemic or pulmonary venous connections were encountered isolated or in combination in 17 patients (10%) among a series of 170 modified Fontan-Kreutzer procedures. Fourteen of these 17 patients (82.3%) survived their operations, which utilized different techniques to deal with the various forms of anomalous systemic and pulmonary venous connections. There was one late death (5.8%). Extracardiac exclusion of a left superior vena cava with an end-to-side left cavopulmonary shunt proved to be a more successful alternative than the use of complicated intratrial baffles. Because of the complexity of the anatomic variables, repair of anomalous systemic or pulmonary venous connections in conjunction with a modified Fontan-Kreutzer procedure requires a detailed preoperative anatomical and physiologic diagnosis, and an individualized plan for each patient must be formulated to provide unobstructed venous pathways.
