Compression of trachea due to double aortic arch: demonstration by multi-slice CT scan (MSCT).
Double aortic arch (DAA) is a form of vascular ring, completely encircling trachea and esophagus by its connecting segments, and thus can lead to clinical picture of aero-digestive tract obstruction. MRI and CECT in addition to the location and extent of aero-digestive tract obstruction can also delineate adjacent cardio-vascular anatomy. 3D reconstruction of aorta and airway can be useful tool for pre-operative planning.
