“…Furthermore, CTA can display the location of the affected region by aortic movement in the tear but often display motion artifact in which the image of the aortic valve and the sandwich lumens in the arteries is likely to be characterized by two parallel arcing low-density shadows. In some cases, AD involving the aortic valve opening and normal aortic valve opening forms are di cult to distinguish, potentially producing false results that might in uence the choice of the surgical intervention [20]. In many non-acute patients, multiple tears may appear on the torn artery intima, and some small tears may be di cult to detect on single-phase images [16].…”

Purpose: Early diagnosis of aortic dissection (AD) and end-organ malperfusion is of great significance for AD’s management and prognosis. This study aimed to evaluate the use of aortic dynamic computed tomography (CT) angiography (CTA) in diagnosing AD and the significance of evaluating blood supply to abdominal organs. Methods: The patients with confirmed AD and who visited our hospital from 12/2018 to 12/2019 were retrospectively included. The densities of the aortas and abdominal organs were measured, and a time-density curve was drawn and compared with conventional CTA. Correlation analysis was performed between the changes of densities in the false lumen and the changes of densities in injured kidneys. Results:Fifty patients were included. The tears were seen in 86%. The main aortic branches were involved in 48%. The diagnostic rate of dynamic angiography for rupture was 86%, slightly better than aortic CTA (84%, P<0.01; κ=0.765). The density of the true and false lumens was measured in each phase: phase 2 (4%), 3 (4%), 4 (48%), 5 (26%), and 6 (16%). Eighteen patients had single renal artery involvement. In phase 7, the density of the AD false lumen and kidney damage were correlated (r=0.75, P<0.001). Conclusions: Dynamic angiography can show the fine structures of AD. In dynamic angiography, the best phase can be selected according to the hemodynamic changes of patients to complete the diagnosis. False lumen density in phase 7 was correlated with renal injury.

Background: The preferred treatment for uncomplicated type B dissection (thoracic endovascular aortic repair [TEVAR] or medical) is still under debate. Since 2001, our center has performed TEVAR for uncomplicated type B dissection. Based on our data, 5- and 10-year survival rates among patients with uncomplicated type B dissection after TEVAR were 96.5% and 83.0%, respectively. We, therefore, believe that TEVAR is preferable for uncomplicated type B dissections. This study analyzed the impact of a pre-operative smoking history on long-term survival after TEVAR in patients with uncomplicated type B dissections. Methods: From May 2001 to December 2013, data from 751 patients with type B dissections were collected and analyzed. Patients were divided into two groups (337 smoking patients and 414 non-smoking patients). The Kaplan-Meier method and log-rank test were used to compare survival curves of the two groups. Multivariable analyses using the Cox proportional hazards model were used to estimate the effects of smoking on survival rates. Results: The 5- and 10-year survival rates of non-smokers were 97.6% (95% confidence interval [CI], 96.0%–99.2%) and 87.0% (95% CI, 81.6%–92.7%), respectively, and 94.9% (95% CI, 92.2%–97.7%) and 73.8% (95% CI, 62.3%–87.5%) for smokers, respectively (Log-rank test, P = 0.006). Multivariable analyses showed that smoking increased the risk of death during follow-up, 2.1-fold when compared to non-smokers (P = 0.039). Conclusion: A pre-operative smoking history increases long-term mortality rates after TEVAR in patients with uncomplicated type B dissections.
