ABSTRACT
Regarding the pleural space after pneumonectomy for malignancy, a vast number of studies have assessed early drop in the fluid level, suggesting a broncho-pleural fistula, but only a small number of studies reported on the abnormal increase in the fluid level-a potentially lethal complication. In the present study, the available databases worldwide were screened and 19 cases were retrieved, including 14 chylothorax and 3 hydrothorax cases, 1 pneumothorax and 1 haemothorax case. Tension chylothorax is caused by mediastinal lymph node dissection as an assumed risk in radical cancer surgery. For tensioned haemothorax, the cause has not been elucidated, although lymphatic stasis associated with deep venous thrombosis was suspected. Tensioned pneumothorax was caused by chest wall damage after extrapleural pneumonectomy combined with low aspiration pressure on the chest drain. No cause was determined for none of the tensioned hydrothorax-all 3 cases had the scenario of pericardial resection in addition to pneumonectomy in common. Tensioned space after pneumonectomy for cancer manifests as cardiac tamponade. Initial management is emergent decompression of the heart and mediastinum. Final management depends on the fluid type (chyle, transudate, air, blood) and the medical context of each case. Of the 19 cases, 12 required a major surgical procedure as the definitive management.
ABSTRACT
We are reporting a case of natural evolution and pathological data from a young person that was diagnosed with coronavirus disease 2019 (COVID-19). All data has been collected from the autopsy of a 30-year-old female, which was performed by the Department of Forensic Medicine from Emergency County Hospital, Drobeta Turnu Severin, Mehedinti County, Romania. The infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was confirmed by reverse transcription polymerase chain reaction (RT-PCR) on the lung tissue which was obtained during autopsy. This case provides the opportunity to study the natural evolution of COVID-19 pneumonia in a young person with clinical signs of pneumonia but without associated comorbidities. The patient had not received any treatment. The histopathological examination of the lung revealed a process of productive proliferation, proteinaceous and fibrin-macrophagic interalveolar spaces exudate, and lesions consistent with vasculitis. In the heart, we identified a cardiac thrombus. These changes are likely to suggest an advanced natural evolution of SARS-CoV-2 virus infection.
