Iatrogenic aortic dissection during left subclavian artery stenting: immediate detection by calcium sign under fluoroscope.
Calcified aorta with acute iatrogenic aortic dissection is a potential but rarely reported complication of subclavian or innominate artery intervention. We report a patient who developed aortic dissection during stenting for left subclavian artery. A newly developed "calcium sign," signifying displacement of the intimal calcification from the outer soft-tissue margin and which is traditionally recognized on chest radiograph, was detected by real-time fluoroscopy and served as the diagnostic clue. Type B aortic dissection was further confirmed by chest computed tomography.
