Large Pericardial Effusion-Diagnostic and Therapeutic Options, with a Special Attention to the Role of Prolonged Pericardial Fluid Drainage.

Abstract

Background: Large pericardial effusion (LPE) is associated with high mortality. In patients with cardiac tamponade or with suspected bacterial etiology of pericardial effusion, urgent pericardial decompression is necessary. Aim: The aim of the present retrospective study was to assess the short-term results of pericardial decompression combined with prolonged drainage in LPE. Material: This study included consecutive patients with LPE who had been treated with pericardial fluid drainage between 2007 and 2017 in the National Tuberculosis and Lung Diseases Research Institute. Methods: Echocardiographic examination was used to confirm LPE and the signs of cardiac tamponade. Pericardiocentesis or surgical decompression were combined with pericardial fluid (PF) drainage. Short-term effectiveness of therapy was defined as less than 5 mm of fluid behind the left ventricular posterior wall in echocardiography. Results: The analysis included 74 patients treated with pericardial fluid drainage (33 female and 41 male), mean age 58 years, who underwent pericardial decompression. Out of 74 patients, 26 presented with cardiac tamponade symptoms. Pericardiocentesis was performed in 18 patients and pericardiotomy in 56 patients. Median PF drainage duration was 13 days. In 17 out of 25 patients with neoplastic PF, intrapericardial cisplatin therapy was implemented. In 4 out of 49 patients with non-malignant PF, purulent pericarditis was recognized and intrapericardial fibrinolysis was used. Short-term effectiveness of the therapy was obtained in all of patients. Non-infective complications were noted in 16% of patients and infective ones in 10%. Conclusion: Pericardial decompression combined with prolonged PF drainage was safe and efficient method of LPE treatment.
