A 64-year-old woman with history of stable chronic type B aortic dissection was admitted with signs and symptoms of malperfusion of the lower body. Spiral computed tomography (Figure 1A and 1B
) and aortography (Figure 2) revealed no propagation of dissection with involvement of abdominal collateral and terminal branches, while disclosed expansion of the false lumen compressing the true one and creating a coarctation-like pattern.

Figure 1. (A) Axial contrast enhanced spiral-CT image: expansion of the false lumen (*), with compression of the true lumen (Arrow). (B) Oblique sagittal multiplanar reconstructed contrast-enhanced spiral CT image: expansion of the partially thrombosed false lumen (*), with compression of the true lumen immediately after the origin of the left subclavian artery (Arrows).
