In conclusion, total endovascular aortic arch
repair using parallel graft technique is a method that can be preferred in emergency situations where surgical treatment is high risk as in the case presented herein.
The most common RSG spread according to Mercante et al.'s Cross-Sectional Imaging CT classification system was in between the thoracic inlet and aortic arch
convexity as cranio-caudal.15 In the study of Khairy et al., the gland's left lobe extension was more similar to ours.18 On the contrary, in the study of Rugiu et al., the right lobe retrosternal spread was greater.14 As a different classification example, in the study of Malvemyr et al.
An a-SMA-positive protrusion formed in the dorsal wall of the aortic sac between the fourth and sixth aortic arch
arteries and extended into the OFT.
Chest x-ray PA view revealed dextrocardia, aortic arch
is on right side.
The CFD simulation seeks to characterize the complex three-dimensional flows in an aortic arch
bench-top model during physiological pulsatile flow.
Left aortic arch

Congenital aortic arch
anomalies represent a diverse set of malformations with a common embryologic origin and a wide array of clinical manifestations.
Some investigators have identified that the rate of sternotomy was higher among patients with RSG whose goiter was below the lower limit of the aortic arch
or extended toward the posterior mediastinum, or in the presence of ectopic mediastinal goiter, recurrent goiter or malignancy adhered to mediastinal structures (13-15,19).
The Aortic Arch
Related Cerebral Hazard (ARCH) trial which randomized patients to aspirin plus clopidogrel or warfarin in patients with an aortic arch
plaque > 4 mm found that ischemic stroke occurred less frequently in the aspirin plus clopidogrel group; however, these results were statistically insignificant .
American Heart Association (AHA) guidelines regarding prevention of stroke in patients with stroke and transient ischemic attack recommend that patients with adherent or mobile aortic arch
thrombus should be treated medically to minimize cerebral embolic events rather than undergone an aortic arch
endarterectomy or a cardiac procedure due to increased rate of intraoperative stroke .
Substernal goiters that extend from the aortic arch
to the pericardium cannot be approached via a cervical incision alone without risk.
A chest radiograph revealed a cardiothoracic ratio of 66%, right-sided aortic arch
, and prominently dilated PA without pulmonary congestion (Figure 1(a)).
