Trans-sternotomy, snare-assisted thoracic endovascular aortic repair for redirection of a migrated elephant trunk.

The two-stage elephant trunk (ET) and thoracic endovascular aortic repair technique for type A and B aortic dissection can result in complications between the two stages. We have presented the case of a patient with an acute-on-chronic type B aortic dissection complicated by ET kinking and migration into the false lumen. We used a hybrid approach consisting of a first stage (retrograde thoracic endovascular aortic repair) and a second stage ("body floss" with antegrade thoracic endovascular aortic repair) to successfully reposition the ET back into the true lumen.
