Fig. 15A 46-year-old woman with long history of hypertension and
recent diagnosis of congenital coarctation of aorta presented for balloon
angioplasty of coarctation. Angioplasty was performed with near-complete
resolution of initial pressure gradient of 37 mm Hg, but was complicated by
type B aortic dissection. Oblique sagittal maximum-intensity-projection (MIP)
contrast-enhanced MR angiogram shows type B dissection (arrowheads),
which extends from just below coarctation (arrow) to level of celiac
axis. She subsequently underwent stent placement.
