The mean volume of pericardial fluid drained after window creation was 446.23 \u00b1 199.81 cc (75\u20131100 cc). The mean operation time was 42.87 \u00b1 12.79 min, and chest drain removal occurred after an average of 1.8 \u00b1 1.2 days. The mean duration until discharge or referral to the follow-up clinic was 5.98 \u00b1 2.14 days. In addition to the pericardial window procedure, pleural biopsy was performed in 12 patients, mediastinal mass biopsy in eight patients and wedge resection for parenchymal nodules in six patients. Microbiologic and virologic cultures of the fluids were negative in all cases. Among the 41 patients with benign cytology, pericardial biopsy results indicated tuberculosis in four patients (5.4%), amyloidosis in one patient (1.3%) and chronic or subacute nonspecific pericarditis in the remaining patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n
