Procedures:
In total, 11 of 15 PPE and EMP patients underwent thoracentesis. Two patients had pleural glucose levels <40 mg/dL. The mean pleural lactate dehydrogenase level was 1825.48±1484.00 U/L. A chest tube (GT) was inserted in 9 (50%) patients. Moreover, 4 (26.66%) patients who had fibrous septations on thoracic USG received TPA at an average of 2.60±1.14 times. The mean chest tube duration was 9.10±6.3 days. One patient with a GT inserted in another hospital who did not have enough pleural fluid during follow-up but who had septal effusion with intense content on thoracic USG was treated with VATS. Further, he was followed-up 5 days after surgery and was discharged on the 10th day of admission.
