Endovascular Treatment with Arch Vessel Reconstruction on Patients with Kommerell Diverticulum and Aberrant Left Subclavian Artery

Right Carotid Artery Origin Compression Caused by Endovascular Repair for Kommerell Diverticulum Associated with a Right-Sided Aortic Arch

“…Notably, Zalle et al reported a similar case with a right-sided arch who showed compression of the right carotid artery origin after arch endografting, which was relieved through bare stent placement. 10) Although a prompt stent placement of the right carotid artery ostium should be considered as a rescue treatment, a spring-back force of the endograft persistently affects the origin of the right carotid artery afterward, as was observed in the present case. Thus, if an external compression of the right carotid artery after arch endografting is anticipated preoperatively, a parallel endografting may be appropriate as a right subclavian artery revascularization because the right subclavian artery would work as an inflow of a secondary right carotid artery bypass grafting.…”
