Diagnostic Pericardiocentesis
Pericardiocentesis is a relatively safe procedure when guided by echocardiography, especially when large free anterior pericardial effusion is present. Pericardial fluid should be aspirated and tested for the presence of malignant cells and tumor markers, particularly in patients with hemorrhagic effusion without preceding trauma. However, hemorrhagic pericarditis in developing countries could be due to tuberculosis. Sensitivity of cytological analysis of pericardial fluid for malignant cells was 67%, 75%, and 92% in different studies with specificity of 100%. Immunohistochemistry can be used to distinguish between the malignant cells and their possible origin.[1][2][3][4][5][6]
Aspirated fluid can also be used for the following tests:
- Gram staining
- Acid-fast staining
- Microbial culture
Pericardial Biopsy
If the clinical suspicion of malignancy is high, and if the results of cytology testing from the pericardiocentesis are negative, consideration should be given to performing a pericardial biopsy. This can be performed via either a subxiphoid or transthoracic pericardiostomy or alternatively by pericardioscopy. The advantages of pericardioscopy include helping to directly visualize the pericardium as well as helping to collect the biopsy sample. Pericardioscopy has an excellent sensitivity of 97%, which compares quite favorably to a blind biopsy which has a low sensitivity of 55-65%.[5][7]
