“…In fact, the diagnosis of an diameters of the ascending aorta (39.4 ± 6.7 mm) and descending aorta (34.5 ± 7.9 mm) and the arch angle (103.8 ± 25 degrees). 22 Rylski et al 23,24 reported similar geometric changes before and after the onset of acute aortic syndromes, including aortic dilatation and increased aortic tortuosity. Schäfer 17 also demonstrated in patients with elevated aortic stiffness that the wall shear stress and timeaveraged wall shear stress were significantly reduced from zones 1 to 4 and the oscillatory shear index was significantly elevated in zones 0, 1, and 4, which predicted the development of severe aortopathy.…”

“…Age‐related changes in the aortic geometry, including dilatation of the aorta, a decrease in the curvature of the arch and clear aortic unfolding, contribute to increasing the aortic stiffness . However, compared with healthy elderly individuals in Asian populations, uncomplicated patients with IMHB showed clear changes in the diameters of the ascending aorta (39.4 ± 6.7 mm) and descending aorta (34.5 ± 7.9 mm) and the arch angle (103.8 ± 25 degrees) . Rylski et al reported similar geometric changes before and after the onset of acute aortic syndromes, including aortic dilatation and increased aortic tortuosity.…”

Objectives It is difficult to predict the evolution of uncomplicated type B intramural hematoma (IMHB) with a focal intimal disruption (FID) in the acute phase. The aims of this study were to investigate the predictors of FIDs and summarize the risk factors for the evolution of uncomplicated IMHB in the acute phase. Methods Eighty‐six patients with uncomplicated IMHB were included and were divided according to the development of an FID during the acute phase: the FID group (n = 32) and the no‐FID group (n = 54). Geometric measurements and computed fluid dynamic calculations were based on a computed tomography scan performed on admission. Multivariate logistic regression analysis was used to estimate the predictors of FID development. Results Thirty‐two (37%) patients developed an FID. Patients with an FID had higher C‐reactive protein levels (18.6 ± 2.3 vs 8.1 ± 0.2 mg/dL, P < 0.001) and white blood cell counts (10.3 ± 2.1 vs 7.5 ± 1.7 109/L, P < 0.001). The no‐FID group had lower occurrences of disease progression (15% vs 64%, P < 0.001) and aorta‐related mortality (6% vs 25%, P = 0.016). Multivariate logistic regression analysis indicated a significant risk for the occurrence of an FID with a larger maximum aortic diameter (OR, 1.35; 95% CI, 1.05‐1.73, P = 0.020), thicker hematoma (OR, 2.20; 95% CI, 1.40‐3.48, P = 0.001), and higher oscillatory shear index (per 0.01 unit, OR, 1.74; 95% CI, 1.21‐2.49, P = 0.003). The aorta‐related mortality during the acute phase was 25% (n = 8). Conclusions Certain aortic conditions, including ta larger aortic diameter, thicker hematoma and higher oscillatory shear stress, are associated with the FID development and result in worse clinical outcomes.

“…Aiming to better understand the anatomical characteristic of the aortic arch, lots of studies on the analysis of aortic arch anatomical parameters had been carried out recently, with the study population consisted of patients either with aortic pathology or health controls (22)(23)(24)(25)(26)(27)(28). The most widely applied parameters included the diameter of different aorta segment, the clockwise angle and take off angle of the supra aortic branches, the type of aortic arch and the angle of the aortic curvature and etc.…”

“…It has been proven that the diameter of the aorta as well as the length of aortic arch and the ascending aorta increase with age [ 4 – 6 ]. Chiu et al proposed an aortic arch measurement [ 24 ]. It requires the designation of a central line and the application of the points of origin of the aortic arch branch vessel.…”

Traumatic aortic injury: does the anatomy of the aortic arch influence aortic trauma severity?

PurposeTraumatic aortic injury (TAI) is a rare but life-threatening type of injury. We investigate whether the anatomy of the aortic arch influences the severity of aortic injury.MethodsThis is a retrospective study of twenty-two cases treated with TEVAR for TAI in our department from 2009 to 2014. Aortic injury was assessed in accordance with the recommendations of the Society of Vascular Surgery. We measured the aortic arch angle and the aortic arch index, based on the initial angio-CT scan, in each of the analyzed cases.ResultsThe mean aortic arch index and mean aortic arch angle were 6.8 cm and 58.3°, respectively, in the type I injury group; 4.4 cm and 45.9° in the type III group; 3.3 cm and 37° in the type IV group. There were substantial differences in both the aortic arch index and the aortic arch angle of the type III and IV groups. A multivariate analysis confirmed that the aortic arch angle was significantly associated with the occurrence of type III damage (OR 1.5; 95% CI 1.03–2.2).ConclusionsThe severity of TAI is influenced by the sharpness of the aortic arch. There is an inverse relationship between the severity of aortic injury and the aortic arch index.
