Pericardioscopy as adjunct to pericardial window.

A G Little, M K Ferguson

    Chest
    |January 1, 1986
    PubMed
    Summary

    Pericardioscopy, a safe surgical technique, aids in diagnosing malignant pericardial effusion when other methods are inconclusive. This method enhances visualization of the pericardium, improving cancer detection during subxiphoid pericardial window procedures.

    Area of Science:

    • Cardiology
    • Surgical Oncology
    • Diagnostic Imaging

    Background:

    • Malignant pericardial effusion presents diagnostic challenges.
    • Subxiphoid pericardial window is a common procedure for effusion management.
    • Limitations exist in definitively diagnosing pericardial malignancy during surgery.

    Purpose of the Study:

    • To evaluate the utility of pericardioscopy during subxiphoid pericardial window surgery.
    • To assess the safety and efficacy of this diagnostic technique.
    • To determine its role in identifying pericardial malignancy.

    Main Methods:

    • A rigid mediastinoscope was used for pericardioscopy in 17 patients.
    • Patients underwent the procedure during surgery for suspected malignant pericardial effusion.
    • Visual inspection of pericardial surfaces was performed.

    Main Results:

    • Pericardioscopy identified malignancy missed by other methods in one patient.
    • Palpable metastatic deposits were confirmed in two patients.
    • The procedure was safe, with transient arrhythmias as the main adverse event.

    Conclusions:

    • Pericardioscopy is a safe and valuable adjunct to subxiphoid pericardial window surgery.
    • It improves the diagnostic accuracy for malignant pericardial effusion, especially in cases with central tumors.
    • This technique is particularly useful when the window procedure alone is not clearly diagnostic.
