Aortic Dissection and Renal Failure in a Patient with Severe Hypothyroidism
Figure 1
(a)–(c) Show the 3-dimensional reconstructs of the aortic dissection, with (d), (e), and (f) showing cross-sectional images through different parts showing the dissection. In summary, the CT angiogram demonstrated that there was a Type B Aortic dissection beginning in the descending thoracic aorta in the distal arch just past the origin of the subclavian artery. The true lumen was small in size and anterior right aspect of the aorta with a larger false lumen. The dissection extends into the abdominal aorta as shown in (a)–(c). As mentioned, the dissection extends into the abdomen. The true lumen is nearly completely collapsed at the level of the celiac and superior mesenteric arteries. Minimal contrast enhancement is seen entering the right renal artery and no enhancement of the left renal artery is noted (f). Again, the distal aortic limb is nearly completely occluded with extension of the dissection in both common iliac arteries.
