CTICasesIatrogenic Retrograde Brachiocephalic Dissection
Imaging findings
Post-operative CT angiography in a patient who underwent ascending aortic aneurysm repair (Zone 1) and frozen elephant trunk placement shows a dissection flap in the right brachiocephalic (innominate) and subclavian artery, with reentry into the brachial artery. The ascending aortic repair graft is intact.
Key takeaways
Aortic surgery utilizing cardiopulmonary bypass can be complicated by iatrogenic arterial dissection. Cannulation of the axillary artery can lead to a retrograde dissection propagating proximally into the subclavian and brachiocephalic arteries. These are often managed conservatively in the absence of malperfusion.
