Surgery for tumors with cavoatrial extension.

Area of Science:

• Oncology
• Cardiovascular Surgery
• Surgical Oncology

Background:

• Intracardiac extension of infradiaphragmatic tumors is a rare surgical complication.
• Renal cell carcinoma is the most frequent malignancy encountered.
• Other tumors include Wilms' tumor, uterine tumors, adrenal tumors, hepatoma, and lymphoma.

Purpose of the Study:

• To highlight the surgical challenges associated with intracardiac tumor extension.
• To discuss the multidisciplinary approach required for resection.
• To present the optimal surgical technique for tumor removal.

Main Methods:

• Multidisciplinary surgical team involvement (cardiothoracic surgeon, urologist, gynecologist).
• Utilization of cardiopulmonary bypass.
• Application of deep hypothermic circulatory arrest.

Main Results:

• Surgical resection is feasible with appropriate techniques.
• Cardiopulmonary bypass and deep hypothermic circulatory arrest offer a safe method.
• Successful removal of intracardiac tumor extensions is achievable.

Conclusions:

• Intracardiac extension of infradiaphragmatic tumors necessitates specialized surgical expertise.
• A combined surgical approach is crucial for effective management.
• Deep hypothermic circulatory arrest with cardiopulmonary bypass is the gold standard for safe and effective resection.
