To describe findings in, and the clinical course and outcome of, aortic dissection (dissecting aneurysm) caused by angiographic procedures. ⋯ Angiographers should be aware of this potentially serious complication. The extent and type of the aortic dissection can be determined with CT.
-
To determine the structures responsible for the left-sided indentation in right aortic arch (RAA) with aberrant left subclavian artery (ALSA). ⋯ The aortic diverticulum appears to be an important factor in the production of the left-sided esophageal defect in patients with RAA with ALSA.

One intact and one ruptured single-lumen implant were surgically placed in a rabbit. Magnetic resonance (MR) imaging was performed before and after surgical removal, and the ruptured implant was imaged after removal of the implant shell. Multiple curvilinear hypointense lines (linguine sign) were present in the MR images of the ruptured implant and of the implant shell alone immersed in saline solution but not in the image of the free silicone. The collapsed implant shell in a ruptured silicone implant does cause the linguine sign.
