Technical problems during the frozen elephant trunk technique for acute type A dissection led to a distortion of the hybrid stent graft, requiring interventional aortoplasty to re-establish flow.
Case Report (n=1)
The frozen elephant trunk technique for acute type A dissection carries a risk of stent graft distortion, highlighting the need for careful consideration and potential rescue with interventional aortoplasty.
Stent graft distortion during FET for acute type A dissection may require rescue aortoplasty; leaves open questions on technique optimization.
We describe a case of an acute type A dissection, where technical problems during the frozen elephant trunk technique led to a distortion of the hybrid stent graft with severe stenosis of the thoracic aortic endoprosthesis. Interventional aortoplasty was performed to re-establish flow. This new technique bears some risk of technical failure and therefore should be applied only after careful considerations.
