INTRODUCTION: Patients that present with recurrent hemoptysis after thoracic aneurismal repair should be highly suspected for collateral bronchial artery circulation as a potential cause of persistent pulmonary hemorrhage.
CASE PRESENTATION: Seventy-five year old female presents with a 6 month history of recurrent hemoptysis. Her past medical history is significant for descending thoracic aneurysm repaired with stent, non small cell lung CA s/p left lower lobe (LLL) resection, and aspergillosis infection diagnosed by bronchoscopic biopsy. Hemoptysis continued throughout the admission despite treatment for aspergillosis, and multiple bronchoscopies performed. On day 5 of admission patient developed massive hemoptysis, requiring intubation for airway protection and was transferred to the intensive care unit. Follow up bronchoscopy showed diffuse right lower lobe hemorrhage and oozing from the LLL stump, with no clear source of bleeding. The following day a pulmonary angiogram also failed to show areas of active bleeding. Throughout this time the patient continued to have mild hemoptysis but remained afebrile. On day 10 the patient underwent a bronchial artery angiography, which discovered collateral circulation from the thyrocervical trunk to the right bronchial artery. This was thought to be the source of pulmonary hemorrhage and embolization was performed. Repeat bronchoscopy the following day showed scattered blood clots bilaterally but no active bleeding. Patient was transferred to a regional floor one day later, and discharged to home three days after, with no recurrent episodes of hemoptysis.
DISCUSSION: This case represents the importance of understanding the anatomical variation of the bronchial arteries in the setting of patients with previous endovascular repair and persistent hemoptysis
CONCLUSIONS: Patients that fail to show a clear source of bleeding with routine thoracic angiography and bronchoscopy should have angiographic evaluation of all possible collaterals.
