For each of the following questions, select the most appropriate answer from the above list of options. Each option may be used once, more than once or not at all. Which artery arises from the aortic arch to supply the left upper limb?From which vessel does the right subclavian artery arise?Upon entering the base of the neck the axillary veins become which vessel?Which artery can be palpated at the front medial aspect of the elbow?Which vein drains the radial side of the forearm?

The right subclavian artery usually arises from the brachiocephalic trunk. An aberrant right subclavian artery arises directly from the aortic arch after the left subclavian artery and then passes back towards the right side, frequently posterior to the oesophagus and hence can cause an indentation.

The right subclavian artery arises from the brachiocephalic artery, whereas the left arises from the arch of the aorta, in a similar arrangement to the common carotid arteries. The subclavian arteries travel laterally towards the arm. The first part of the subclavian artery, from its origin to the medial aspect of the anterior scalene muscle, gives off the vertebral artery, the internal thoracic artery and the thyrocervical trunk, from which the inferior thyroid artery, suprascapular artery and the transverse cervical artery arise. The first part of the subclavian artery lies deep to sternocleidomastoid and the strap muscles but may extend above the clavicle so is at risk during procedures in the supraclavicular fossa. The second part of the artery runs deep to the anterior scalene muscle and gives off the costocervical trunk and the dorsal scapular artery. The third part passes lateral from the edge of the anterior scalene towards the arm and has no branches in the neck.
Dysphagia lusoria in a young woman with chest pain

Dysphagia lusoria (from Latin lusus naturae, freak of nature) was first described in 1761 by surgeon David Bayford, who discovered a fatal case of obstructed deglutition.1 Dysphagia lusoria is a congenital abnormality of the aortic arch characterized by an aberrant subclavian artery that compresses the esophagus and causes dysphagia. An aberrant right subclavian artery occurs more often than an aberrant left subclavian artery. This right subclavian artery anomaly occurs in 0.4% to 1.8% of the population and is characterized by absence of the brachiocephalic trunk and a right subclavian artery that arises directly from the aortic arch instead of originating from the brachiocephalic artery, crosses the midline, and compresses the esophagus.

It should be noted that placing a surgical Impella does add some risks and resource utilization compared with percutaneous devices. Surgical Impella placement is usually done in the operating room under general anesthesia, with endotracheal intubation. Both the transport to the operating room and the induction of anesthesia can be dangerous, whereas percutaneous devices can be placed with only local anesthetic. Additionally, surgical Impella placement requires surgical incisions, which may exacerbate bleeding. One must also pay attention to patient-specific anatomic considerations, including an aberrant right subclavian artery and possible obstructions due to pacemakers and other devices.
Aortic arch anomalies detected in foetal life by echocardiography

Aberrant right subclavian artery is one of the aortic arch anomalies and its incidence is reported as 2% in normal individuals (Atanasova et al. 2015). However, in our study, ARSA was detected in only three patients with no other abnormality. But Atanasova et al. (2015) reported that; in four of 17 cases with ARSA, Down syndrome and Trisomy 18 were diagnosed. We considered that some of the patients with ARSA were missed during our study period and this is the most important limitation of our study.
