Hybrid management of proximal right subclavian artery aneurysms

Surgical repair of proximal right subclavian artery aneurysms can be difficult. They typically require a combined mediastinal exposure to control the innominate and right common carotid arteries and a supra- or infraclavicular exposure for distal control, with either a segmental resection and bypass or a bifurcated reconstruction. In this report, we present four cases utilizing a single-stage, hybrid technique combining an endovascular stent graft and an extra-anatomical bypass to repair proximal right subclavian artery aneurysms without the need for mediastinal exposure or extensive surgical reconstruction. There were no deaths and two minor neurologic events
