Commentary on “Multibranched Frozen Elephant Trunk with Left Subclavian Artery Cannulation” by Martinelli, G.L. et al.

[摘要] The paper by Martinelli et al. [1] presents a variant of the frozen elephant trunk procedure for repair of pathology in the ascending aorta, aortic arch, and proximal descending aorta. The authors take the approach of performing the distal anastomosis in an extraanatomic location proximal to the innominate artery. Their other modification involves a sidearm graft to the subclavian artery, which is used initially for perfusion and subsequently for permanent anastomosis to the main graft.
