Pre-operative volume rendering CT angiogram imaging demonstrating: (a) a right-sided arch, aberrant origin of the left subclavian artery and (b) a Kommerel's diverticulum at its origin. LSA: left subclavian artery; LCCA: left common carotid artery; RCCA: right common carotid artery; RSA: right subclavian artery.

He had been investigated at his local hospital with an oesophagoduodenoscopy (OGD), that had revealed mild extrinsic compression of the oesophagus and a computed tomography (CT) (Figure 1(a) and (b)) scan that revealed a right-sided arch with an aberrant left subclavian artery passing posterior to the oesophagus.
Intra-arterial DSA in right anterior oblique projection: (a) diagnostic angiogram prior to stent deployment, (b) after stent deployment and cannulation of the posterior tunnel (right common carotid artery), (c) after cannulation of the anterior tunnel (left common carotid artery) and (d) completion angiogram after deployment of bridging stent grafts.
