摘要

Background

Microscopic polyangiitis (MPA) is a rare disease characterized by systemic vasculitis. However, perioperative endobronchial haemorrhage in these patients is not well-documented in medical literature.

Case presentation

We present the case of a 62-year-old woman with MPA who developed massive airway bleeding during thoracoscopic mitral valve replacement. The haemorrhage was successfully managed with bronchoscopic localization and bronchial artery embolization, which led to a rapid recovery.

Conclusion

This case increases the awareness of endobronchial haemorrhage in patients with MPA and underscores the critical role of a prepared, multidisciplinary team in achieving a successful outcome.
