Contemporary surgical and endovascular techniques provide a broad arsenal of possible treatments and imaging techniques and modeling technology allow a more personalized strategy for each patient. In this case we present a symptomatic patient with a Kommerell's diverticulum with a left aberrant subclavian artery complicated with a proximal stenosis and a poststenotic aneurysm. An hybrid technique using a single-branched thoracic stent-graft (Castor, MicroPort Medical, Shanghai, China) in combination with a surgical left subclavian-carotid bypass and an endovascular occlusion of the poststenotic aneurysm with a vascular plug device (Amplatzer Vascular Plug, Abbott, Chicago, United States) was performed. This approach was planned and PAGE \* Arabic \* MERGEFORMAT 4 facilitated by the use of a 3D model. Alternative treatment options and the strengths of this approach are briefly reviewed and discussed.
