rechts descendierende Aorta mit aberrierender linker Arteria subclavia

Right-sided

aortic arch with aberrant left subclavian artery. Absent left aortic contour, presence of right aortic knob (red arrow), both hemidiaphragms are flat and low in position.

Infant with

dysphagia. AP image from an upper GI exam (above left) shows a right sided aortic arch and an indentation running at an angle from right to left across the upper esophagus. Lateral image from an upper GI exam (above right) shows a posterior indentation across the upper esophagus. 3D CT with contrast of the chest viewed from the front (below left) shows a right sided aortic arch and a right sided descending aorta and viewed from the back (below right) shows the aberrant left subclavian artery arising from a large diverticulum of Kommerell. The airway (in blue) was not compressed.The diagnosis was right aortic arch with aberrant left subclavian artery.

Toddler with

stridorCXR shows a right side aortic arch. Echocardiogram showed an aberrant left subclavian artery.The diagnosis was right aortic arch with aberrant left subclavian artery.

Right-sided

aortic arch with aberrant left subclavian artery. Anterior view, slightly rotated: 1. left CCA 2. right CCA 3. right subclavian artery 4. left subclavian artery (last branch) 5. Kommerell’s diverticulum 6. right-sided aortic arch

Infant with

dysphagia. AP image (left) from an UGI exam shows a right sided aortic arch and an indentation running across the upper esophagus which on the lateral image (right) shows the indentation to be posterior to the esophagus.The diagnosis was right aortic arch with an aberrant left subclavian artery.

Infant with

choking with feedings. Lateral image from an esophagram (above left) shows a posterior indentation on the esophagus which was persistent. Coronal CT with contrast of the chest (above right) with 3D reconstructions (below) show a right-sided aortic arch with an aberrant left subclavian artery that originated from a Kommerell diverticulum and that courses behind the esophagus. The ductus arteriosus was noted to extend from the Kommerell diverticulum and completed the vascular ring. The diagnosis was right aortic arch with aberrant left subclavian artery.

Right-sided

aortic arch with aberrant left subclavian artery. Lateral view, slight rotation: 1. left CCA 2. right CCA 3. right subclavian artery 4. left subclavian artery (last branch) 5. Kommerell’s diverticulum 6. right-sided aortic arch 7. descending aorta

Right-sided

aortic arch with aberrant left subclavian artery. Lateral view: 1. left CCA 2. right CCA 3. right subclavian artery 4. left subclavian artery (last branch) 5. Kommerell’s diverticulum 6. right-sided aortic arch 7. descending aorta.

Right-sided

aortic arch with aberrant left subclavian artery. Posterior view: Aberrant left subclavian artery (4) arising from Kommerell’s diverticulum(5), a focal dilatation of the arch. 6. right-sided aortic arch 7. descending aorta.

Right-sided

aortic arch with aberrant left subclavian artery. Aortic arch (white arrow) on the right side of distal trachea.

Right-sided

aortic arch with aberrant left subclavian artery. Anterior view: Note the origin of 4 vessels from right-sided aortic arch in the following order. 1. left CCA 2. right CCA 3. right subclavian artery 4. left subclavian artery (last branch)

Right-sided

aortic arch with aberrant left subclavian artery. Right aortic arch (white arrow), distal tracheal deviation to the left (yellow arrow).

Right-sided

aortic arch with aberrant left subclavian artery. Thoracic aorta (white arrow), descending on the right side of the spine then turning to the left to enter the aortic hiatus at normal position.

Right-sided

aortic arch with aberrant left subclavian artery. The descending aorta (D)continues inferiorly on the right side of the vertebral column.

Right-sided

aortic arch with aberrant left subclavian artery. White arrow- right aortic arch, yellow arrow- left CCA, red arrow- aberrant left subclavian artery coursing posterior to oesophagus, S-superior vena cava, T-trachea, O-oesophagus

Right-sided

aortic arch with aberrant left subclavian artery. Aberrant left subclavian artery (red arrow) arising from Kommerell’s diverticulum (white arrow), a focal dilatation of the arch. Yellow arrow-left CCA, S-superior vena cava

Right-sided

aortic arch with aberrant left subclavian artery. Four vessels from the right aortic arch in the following order. Left CCA (yellow arrow), right CCA(green arrow), right SA(blue arrow), left SA (red arrow). Purple arrow-left subclavian vein, T-trachea, O-oesophagus

Right-sided

aortic arch with aberrant left subclavian artery. Lateral scanogram showing right aortic arch with right descending thoracic aorta.

Infant with

cough and fever and a murmur. CXR AP shows a right-sided aortic arch, cardiomegaly, and marked pulmonary vascular congestion.The diagnosis was right aortic arch with aberrant left subclavian artery in a patient with ventricular septal defect.
