Life-Threatening Hemoptysis From Aorto-Bronchial Fistula in a Patient With Remote History of Aortic Coarctation Repair.

"Hemoptysis" refers to the expectoration of blood from the respiratory tract. However, "life-threatening hemoptysis" includes any volume that leads to features such as airway obstruction, hypoxia, or hemodynamic instability. We present a case of life-threatening hemoptysis in a 65-year-old male with a history of benign prostatic hyperplasia and uncontrolled hypertension. Radiological investigations revealed a pseudo-aneurysm at the site of a prior thoracic aortic coarctation repair more than 50 years prior in childhood. He required vascular surgical intervention, during which there was evidence of an aorta-bronchial fistula as the likely cause of bleeding. Following the repair and optimal blood pressure control, the patient had no further episodes of hemoptysis and was discharged from the hospital. His case not only adds to the growing body of medical literature reporting hemoptysis as a complication of coarctation repair but also highlights the aorto-bronchial fistula as a possible and potentially catastrophic mechanism for bleeding in these patients.
