Abstract
Purpose:To determine the frequency, locations, and sizes of aortic intimal tears detected using spiral computed tomography (CT).Methods:CT scans (26 single detector and 26 multidetector studies) from 52 patients with an unoperated aortic dissection and a patent false lumen were evaluated on a workstation. The number, location, and size of aortic tears were recorded and compared between the following groups: acute and chronic dissection, type A and type B, and single detector and multidetector studies.Results:In 52 patients, 129 tears were identified (mean 2.48 per patient, median 2, range 1–7). There were no significant differences in the number or size of tears between the acute and chronic, the type A and type B, or the single detector and multidetector groups (p 0.05)....
