Total arch replacement and frozen elephant trunk for acute type A aortic dissection
The Journal of Thoracic and Cardiovascular Surgery Nov 26, 2020
Iino K, Takago S, Saito N, et al. - The outcomes of total aortic arch replacement (TAR) with proximalization of distal anastomosis using the frozen elephant trunk (FET) technique with the J Graft FROZENIX and Gelweave Lupiae graft (distal anastomosis performed in zones 1 and 2) were examined in patients with acute Stanford type A acute aortic dissection. Researchers here assessed a total of 50 patients who were managed with TAR using the FET technique, deploying the J Graft FROZENIX into zone 1 or 2 (zone1: n = 17, zone2: n = 33) in combination with the Gelweave Lupiae graft for acute Stanford type A acute aortic dissection. Among these patients, the overall in-hospital mortality rate of 4% (2 patients) was reported; patients with visceral malperfusion had in-hospital mortality rate of 11% (1/9). Outcomes support the safety and effectiveness of TAR with the FET technique (zone 1–2) and Gelweave Lupiae graft in simplifying surgery for acute Stanford type A acute aortic dissection.
