A DUMON STENT INSERTED FOR BRONCHIAL STENOSIS CAUSING A LEFT BRONCHOPERICARDIAL FISTULA - REPORT OF A CASE

We present herein the case of a 59-year-old man in whom a Dumon stent, inserted as treatment for stenosis of the left main bronchus, caused a left bronchopericardial fistula, The patient initially presented wit h severe dyspnea caused by main bronchial stenosis of unknown origin f or which a Dumon stent was inserted at a local hospital. The Dumon ste nt migrated to the endobronchus through the stenosis of the left main bronchus a few days later, and his dyspnea remained unresolved. He was subsequently referred to our department 6 months later, where a left pneumonectomy under supportive cardiopulmonary bypass through the femo ral artery and vein was performed, and a postoperative pathological di agnosis of bronchial leiomyosarcoma was made, For this rare group of m alignant tumors, early diagnosis permits complete surgical resection o f the mass and offers the best prognosis. Excision of the tumor should be performed under cardiopulmonary bypass through the femoral vessels when a risk of sudden rupture of the pulmonary artery or vein exists for any reason.
