This case report details the management of a recurrent catamenial pneumothorax case, advocating for combined chemical and mechanical pleurodesis during VATS to prevent recurrence.

Abstract

Catamenial pneumothorax (CP) is an uncommon disease that is challenging to diagnose and manage.It is characterized by recurrent episodes of spontaneous pneumothorax occurring periodically within 72 hours of menses in women of childbearing age.Treatment typically includes video-assisted thoracic surgery (VATS) and hormonal treatment.This case report is of a 37-year-old female who was presented with her fourth episode of recurrent right-sided pneumothorax, her two-year status post-VATS bullectomy, chemical and mechanical pleurodesis, and dienogest treatment.This case report details the natural history of a CP presentation with a high index of suspicion to diagnose, meticulous surgical exploration of the hemithorax, looking particularly for bullae and diaphragmatic pleural endometriosis or fenestrations, and application of both mechanical and chemical pleurodesis to prevent a recurrence.This report should encourage the combined adoption of chemical and mechanical pleurodesis during VATS in CP patients suffering from repeated recurrence.
