Bronchial Dieulafoy Lesion Embolization with Onyx: a Case Report


Bronchial Dieulafoy lesion (BDL) is a rare cause of hemoptysis that is difficult to diagnose. Identification is critical since treatment is challenging and biopsy can be fatal. Treatment options include bronchial artery embolization (BAE), bronchoscopy intervention, and surgery. BAE is first-line treatment, but success rates are currently between 40 and 53%. This case report describes the use of Onyx for treatment of a BDL after multiple failed particle embolizations. BAE with Onyx offers advantages over other embolization techniques and should be considered for use in treatment of BDL.
