Iatrogenic buffalo chest bilateral pneumothoraces following unilateral transbronchial lung biopsies in a bilateral lung transplant recipient

摘要

We present a 54 year old male patient who had a bilateral lung transplant sixteen years ago for Alpha-1 Antitrypsin Deficiency-related emphysema. He was referred for flexible bronchoscopy with transbronchial biopsies to evaluate new mild exertional dyspnea and worsening of his FEV1. Eight transbronchial biopsies were done from the right middle lobe and the right lower lobe. Post procedure he developed bilateral pneumothoces that required emergent bilateral pleural ‘pigtail’ catheters. To our knowledge, this is the first reported case of bilateral pneumothoraces that developed after a unilateral procedure in a bilateral lung transplant recipient relatively late after the transplant.
