The soft elephant trunk: a new approach in the treatment of aortic dissection.

ABSTRACT:

Background

The frozen elephant trunk (FET) technique has revolutionized the surgical management of aortic dissection. However, distal stent-graft-induced new entry (dSINE) and reinterventions remain major challenges. This study presents the long-term results of a dissection-specific (DS) "Soft Elephant Trunk" (SET) (MedEng, Penza, Russia) hybrid prosthesis and its impact on distal remodeling compared to conventional hybrid prosthesis.

Methods

A retrospective review of hybrid aortic repairs from 2014 to 2024 identified 241 patients with aortic dissection. Patients were categorized into two cohorts: DS SET prosthesis (n=170) and conventional prosthesis (non-DS, n=71). Propensity score matching was performed. Primary endpoints included the incidence of dSINE and aortic reinterv
