Predictors of Distal Stent Graft-Induced New Entry after Frozen Elephant Trunk in Acute Type A Aortic Dissection.

ABSTRACT:

Objectives

Distal stent graft-induced new entry (d-SINE) is a significant complication of frozen elephant trunk (FET) for acute Stanford type A aortic dissection (ATAAD). This study aimed to identify the predictive factors for d-SINE occurrence.

Methods

Patients who underwent FET procedures for ATAAD at our institution between January 2015 and December 2024 were retrospectively analysed. Patients were classified into d-SINE positive and d-SINE negative groups, and predictive factors were identified using Fine and Gray competing risk regression.

Results

A total of 84 consecutive patients were included. The overall incidence of distal stent graft-induced new entries was 11.9% (10/84). Distal stent graft-induced new entry occurred at a mean of 102 days (standard deviatio
