There are varying kinds of complications which develop after pneumonectomy. Stated in the present paper are the findings of the pathological investigation of an autopsy case who had developed vascular miliary tuberculosis, pericarditis and bilateral cheesy and fibrinous inflammation of the pleura following the application of the complementary thoracoplasty after receiving the left side total pneumonectomy on account of the presence of cavity in the left upper lobe and capsular cheesy focus in the other lobe.
It was not feasible to clarify, however, whether this serositis developed as a part of the vascular dissipation or the transmission first from the intrathoracic dissipation at the time of operation to the left side pleuritis and then to the right side and further to the pericarditis.
Biopsy findings of the liver are considered to indicate the initial stage of vascular dissipation.
