Abstract

Background: The clinical course of malignancies is frequently complicated by third spacing in body cavities, including pericardial effusion. What remains the optimal management for malignant pericardial effusion is a dilemma.
Aim: We aimed to compare 30-day outcomes of imaging-guided pericardiocentesis and surgical pericardial window in patients with malignant pericardial effusion.
Methods: A retrospective observational study was done at a tertiary care hospital. We reviewed hospital record files of 91 consecutive patients admitted with malignant pericardial effusion from January 2010 to December 2019 and requiring imaging-guided pericardiocentesis or pericardial window.
Results: A total of 71 patients were included in the final analysis. Most patients were male (68%). The mean age was 45 years. Hypertension was the most common comorbid condition. Lymphoma or leukemia (39%) was the most common cause of malignant pericardial effusion followed by lung cancer (28%). About 57.7% of patients underwent pericardiocentesis, and the remainder underwent surgical pericardial window (42.3%). The overall procedural success was 97.2%, and the overall mortality was 5.6%. The success rate was similar when pericardiocentesis was compared with the surgical pericardial window (p = 0.22). The length of hospital stay was higher in patients undergoing pericardial window (p = 0.007), whereas the re-accumulation rate was higher in the pericardiocentesis group (0% versus 34%, p < 0.001). Patients undergoing pericardial window had higher odds of major bleeding requiring transfusions.
Conclusion: There is a higher rate of recurrence following isolated pericardiocentesis but a comparable mortality difference between the two procedures. Complication rates can be reduced by improving surgical technique and peri-operative management. Meticulous surgical care, infection precautions, and good glycemic control in this immunocompromised subset can preserve the pericardial window as a better management option.
Relevance to patients: Pericardial window is a promising and effective management option for patients with recurrent malignant pericardial effusion, but it comes at the cost of bleeding and infection. More extensive trials are needed to understand better the long-term outcomes of pericardial window or pericardiocentesis in patients with malignant effusion.
