Methylene Blue Instillation for the Evaluation of Bronchopleural Fistula

Abstract

A bronchopleural fistula (BPF) is a pathologic communication between a bronchus and the pleural space. BPF has a high morbidity and mortality, therefore a timely diagnosis is of great importance. Methylene Blue has been used for the localization of BPF for decades and although other diagnostic tools are available, it remains favorable because it is widely available, safe and easy to perform. In this case report we would like to stress the ongoing relevance of this diagnostic method by presenting 2 cases in which instillation of Methylene Blue was used in current practice to localize BPF.
