Intimal tears in thoracic aortic dissection: appearance on MDCT with virtual angioscopy.

Abstract

The location, number, size, and configuration of intimal tears in aortic dissection have important therapeutic and prognostic implications. Planning of procedures to treat complications of aortic dissection may require precise delineation of the intimal tears. The purpose of this article is to illustrate the ability of MDCT using multiplanar image reformatting and virtual angioscopy to depict the location and appearance of intimal tears and fenestrations within dissection flaps in cases of thoracic aortic dissection. MDCT with virtual angioscopy can depict the configuration of intimal tears in cases of thoracic aortic dissection, which may facilitate therapeutic planning.
