Aortic reinterventions are common after the frozen elephant trunk (FET) procedure, occurring in 33% of patients. While predictors remain elusive, reinterventions show acceptable outcomes, emphasizing the need for close patient follow-up.
Area of Science:
- Cardiovascular Surgery
- Thoracic Aortic Pathology
- Minimally Invasive Procedures
Background:
- The frozen elephant trunk (FET) procedure is a single-step treatment for thoracic aorta pathologies.
- Its long-term efficacy and need for reintervention require further investigation.
Purpose of the Study:
- To evaluate the incidence and outcomes of aortic reinterventions following FET implantation.
- To identify predictors for aortic reintervention after FET procedures.
Main Methods:
- Retrospective analysis of 107 patients who underwent the FET procedure.
- Comparison of patient characteristics and follow-up data between those with and without reinterventions.
- Competing risk regression to identify predictors of reintervention.
Main Results:
- 33% of patients required aortic reintervention (endovascular, open, or hybrid).
- No significant difference in underlying pathology between reintervention groups.
- No identified independent predictors for reintervention; 36-month reintervention risk was 64%.
Conclusions:
- Aortic reinterventions are frequent after FET procedures.
- Reinterventions are associated with acceptable morbidity and mortality.
- Close patient surveillance post-FET is crucial.

The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...
