[Catamenial pneumothorax: a rare spontaneous pneumothorax associated with the menstrual cycle].

Catamenial pneumothorax is a rare clinical condition that may be difficult to diagnose. Catamenial pneumothorax is defined as spontaneous pneumothorax that occurs within 72 hours before or after the onset of menstruation. It occurs in the right lung in 91.7% of cases. However, the exact pathogenic mechanism and optimal management of catamenial pneumothorax remain unclear. Patients may suffer extensive psychological stress during prolonged diagnostic and therapeutic interventions and follow-up. This article discusses common issues related to catamenial pneumothorax pathogenic mechanisms, symptoms, diagnostic and optimal management, health problems, and nursing care, and provides the opinions of nursing staff with actual case experience.
