Abstract

Background: The impact of type B acute aortic dissection (TBAAD) on historical pre-TBAAD diameters of the thoracic aorta is rarely reported. The aim of this study was to assess the extent of changes in aortic diameters induced by dissection, measured with a computed tomography (CT) scan obtained before and after TBAAD.

Methods: Between January 2004 and December 2014, CT angiography of 50 non-Marfan patients with nonbicuspid aortic valves diagnosed with TBAAD were compared to historical CTs on file.

Results: The ascending aorta and proximal arch showed negligible change. The proximal, mid, and distal aorta diameters changed compared with predissected values (107.7 ± 4.8%, 109.3 ± 4.9%, and 105.7 ± 5.8%, respectively). Neither sex, false lumen status, or mural calcification, nor prior thoracoabdominal aortic ectasia, correlated with the diameter change. Age ≥80 years in the proximal descending aorta did correlate with the diameter change (110.7 ± 4.0% vs 106.1 ± 4.6% p = 0.01).

Conclusions: Although identifying predicting factors for an aortic diameter increase all along with the thoracic aorta was still challenging, the degree of diameter change by aortic dissection was 105.7% to 109.3% in descending thoracic aorta, most prominent in middle descending aorta.

急性 B 型主动脉夹层引起的胸主动脉直径变化。

背景：B 型急性主动脉夹层（TBAAD）对夹层前胸主动脉直径的影响鲜有报道。本研究的目的是评估夹层引起的主动脉直径变化程度，测量方法是在 TBAAD 之前和之后获得的计算机断层扫描（CT）：2004年1月至2014年12月期间，对50名诊断为TBAAD的非马凡氏非双尖瓣主动脉瓣患者进行了CT血管造影，并将其与档案中的历史CT进行了比较：结果：升主动脉和近弓的变化可以忽略不计。主动脉近端、中段和远端直径与解剖前值相比有所变化（分别为 107.7 ± 4.8%、109.3 ± 4.9% 和 105.7 ± 5.8%）。性别、假腔状态、壁钙化或先前的胸腹主动脉异位均与直径变化无关。降主动脉近端年龄≥80 岁确实与直径变化有关（110.7 ± 4.0% vs 106.1 ± 4.6% p = 0.01）：尽管确定胸主动脉全段直径增加的预测因素仍具有挑战性，但主动脉夹层导致胸降主动脉直径变化的程度为 105.7% 至 109.3%，其中以中降主动脉最为显著。

期刊介绍： The Asian Cardiovascular and Thoracic Annals is an international peer-reviewed journal pertaining to cardiovascular and thoracic medicine. Besides original clinical manuscripts, we welcome research reports, product reviews, reports of new techniques, and findings of special significance to Asia and the Pacific Rim. Case studies that have significant novel original observations, are instructive, include adequate methodological details and provide conclusions. Workshop proceedings, meetings and book reviews, letters to the editor, and meeting announcements are encouraged along with relevant articles from authors.
