Coil embolization of a bronchial artery aneurysm originating from the false lumen prior complex endovascular repair for type II postdissection thoracoabdominal aneurysm.

Bronchial artery aneurysm (BrAA) is a rare but potentially life-threatening condition, often associated with aortic pathology. We present a case of a 59-year-old man with a history of Stanford type A acute aortic dissection and subsequent aortic repairs. Surveillance imaging revealed a progressively enlarging right-sided BrAA originating from the false lumen. A staged approach was adopted, beginning with endovascular coil embolization using 18 detachable coils, followed by an open aortic repair. The procedure was successful, with complete aneurysm exclusion and no perioperative complications. This case underscores the technical challenges of BrAA embolization and highlights the efficacy of a multidisciplinary, staged treatment strategy.
