New 3-zone hybrid graft : First-in-man experience in acute type I dissection

2019

Abstract Objective Acute type I aortic dissection (AAD) represents a surgical emergency with time-dependent evolving complications. Frozen elephant trunk (FET) enables false lumen exclusion downstream but is still debated in AAD due to its greater dimension of surgery. To combine the benefits of fast proximal repair with the FET benefits, a 3-zone hybrid graft was developed consisting of an ascending polyester portion, an arch noncovered stent, and a descending stent graft. Mid-term results of this new technique are presented. Methods A total of 6 patients (age mean 69 years) with type I AAD in critical status (Penn classification B n = 5, BC n = 1) were operated between July 2016 and April…
