dicumarol and Fistula

Aortobronchial fistula is a rare but serious cause of hemoptysis. It can develop from an aneurysm of the descending thoracic aorta in the context of infections or it may appear as a sequel of surgical repair of congenital heart defects. Presenting symptoms include mild bronchial hemorrhages and recurrent chest pain, culminating in a normally fatal massive hemorrhage. Diagnosis by imaging is not always conclusive and clinical suspicion based on medical history is essential. Surgical placement of an endovascular stent graft is the treatment of choice. Post-surgical prognosis is good although there is a risk of recurrence in the case of superinfection.
