Thoracoabdominal aortic aneurysm repair after frozen elephant trunk procedure


Folkmann, Sandra; Weiss, Gabriel; Pisarik, Harald; Czerny, Martin; Grabenwoger, Martin (2015). Thoracoabdominal aortic aneurysm repair after frozen elephant trunk procedure. European Journal of Cardio-Thoracic Surgery, 47(1):115-119.

Abstract

OBJECTIVES: To evaluate the feasibility and the outcomes of second-stage thoracoabdominal (TA) repair after previous frozen elephant trunk (FET) implantation.
METHODS: Between 2005 and 2013, 41 patients underwent open TA aortic repair in our institution. Of these, 9 patients (78% male) underwent second-stage TA repair after previous FET implantation. Feasibility and outcomes were evaluated.
RESULTS: The mean interval between FET implantation and second-stage TA repair was 423 days (19-1979 days). Indications for second-stage TA repair were progression in aortic diameter of atherosclerotic aneurysms in the downstream segments in 6 patients, diameter progression in post-dissection aneurysms in 2 patients and giant cell aortitis with aneurysm formation in another patient. There were no in-hospital deaths. The median intensive care unit stay was 3.5 days (range: 1-12 days) and median hospital stay was 22 days (range: 14-132 days). We did not observe symptomatic spinal cord ischaemia or stroke. One patient (11%) developed acute renal failure requiring haemodialysis.
CONCLUSION: Second-stage TA aortic repair after previous frozen elephant implantation is a feasible and effective treatment modality for patients with various pathologies of downstream aortic segments. This approach adds additional value to the conventional elephant trunk technique by providing an excellent landing zone not only for additional stent graft procedures but also for subsequent open TA repair.
