Abstract

<p>Herein, we report a case where negative pressure wound therapy (NPWT) was used for recurrent chronic expanding hematoma. An 83-year-old man underwent a right lower lobectomy for primary lung cancer. Postoperative computed tomography (CT) revealed encapsulated pleural effusion in the right thoracic cavity that slowly increased over 3 years. Cytological examination of the pleural fluid revealed no malignancy, and a diagnosis of chronic expanding hematoma (CEH) was made. Thoracoplasty (resection of the 5th to 10th ribs) was performed. Five months after the thoracoplasty, contrast-enhanced CT showed a 14 × 10 cm area of fluid accumulation in the right subcutaneous region of the chest, which was diagnosed as recurrence of CEH. There was no improvement, despite pleurodesis with OK-432. Thus, the patient underwent open-window thoracostomy, followed by NPWT for 9 weeks. The wound had almost completely healed, and the patient was free of CEH recurrence for 1 year and 1 month after the third surgery. To the best of our knowledge, there have been no reports of patients undergoing NPWT for recurrent CEH. In conclusion, NPWT is useful for treating CEH.</p>
