Pulmonary Artery-Tracheal Fistula After Coil Implantation for Behcet’s Disease

Behcet’s disease (BD) is a rare autoimmune disorder that results in diffuse full-thickness vasculitis. Pulmonary artery aneurysms (PAAs) and hemoptysis are known complications of this disease process, with high morbidity and mortality for affected patients. Although medical, endovascular, and surgical treatment strategies have all been described in the literature, there are little data to describe the long-term outcomes of these various treatment modalities and there continues to be a lack of clearly defined algorithms for the management of these patients. We report a case of PAA in the setting of BD who was treated over the course of many years with medical therapy and coil embolization but ultimately failed treatment, sustained a complication of coil erosion and migration into the trachea twice, and required surgical lobectomy for definitive management. We discuss an algorithm for the management of patients with BD who have PAAs.
