Successful repair of type I endoleak using the Frozen elephant trunk technique

Abstract

Thoracic endovascular aortic repair (TEVAR) has emerged as an effective therapy for a variety of thoracicaortic pathologies. However, various types of endoleak remain a major concern, and its treatment is often challenging. We report a case of type I endoleak occurring 19 months after zone II hybrid TEVAR. The endoleak was successfully repaired by the frozen elephant trunk technique, without removal of a previous stent graft, combined with ascending a orta and total arch replacement.
