Abstract Objective: The purpose of this study was to evaluate the value of dual source CT angiography(CTA) in the pre- and post-hybrid surgery of DeBakey type I aortic dissection. Methods: The pre- and post-treatment CTA data from 11 patients with DeBakey type I aortic dissection undergoing hybrid surgery were retrospectively analyzed; CTA and intra-operative DSA data from 6 patients correlated with CTA. Results: For all 11 patients, DeBakey type I aortic dissection was definitely diagnosed at pre-treatment CTA. Crevasse was localized in the upper part of the ascending aortic root(n=6), the aortic arch(n=3). Organized thrombus in the false cavity was shown in 2 patients. All 11 cases were involved in the thoracic and abdominal aorta, of which 4 cases involved in the branches of aortic arch. Post-operative CTA clearly showed the location of the stents, organized thrombus in the false cavity, reconstructed aortic arch and bypass vessels. Occlusion of the proximal segment of left subclavian artery was demonstrated in two patients, endoleak in one patient; organized thrombus in the false cavity, enlarged true cavity and patent bypass vessels in the remaining 8 patients. Conclusion: Dual source CT angiography plays an important role in the evaluation of the pre- and post-hybrid surgery of DeBakey type I aortic dissection.
