Frozen elephant trunk with the E-vita Open Plus prosthesis

:The Frozen Elephant Trunk (FET) technique, combining conventional surgery with endovascular techniques, allows patients with extensive diseases of the thoracic aorta to be treated with a hybrid single-stage procedure. This article describes our surgical technique and report on our results after such a procedure. METHODS: Between January 2007 and February 2011, 96 patients were treated with FET in our Institution. The mean age was 62±10 years. Indication for surgery included: chronic aneurysm (N.=31; 32.3%), acute type A dissection (N.=6; 6.2%), acute type B dissection (N.=2; 2.0%), chronic type A dissection (N.=44; 45.8%), chronic type B dissection (N.=13; 13.5%). Fifty-three patients (55.2%) had undergone one or more previous cardiac/aortic operations. Forty-three associated aortic/cardiac operations were performed. Brain protection was achieved by means of antegrade selective cerebral perfusion and moderate hypothermia (26 °C) in all cases. RESULTS:Hospital mortality was 14.7%. Postoperatively, major brain complications occurred in 6 patients (6.3%), and paraplegia in 10 (10.4%). Seventeen patients (17.7%) required endovascular completion with a technical/procedural success of 100%. CONCLUSION: The FET is associated with encouraging early results. As compared to the conventional 2-stage elephant trunk approach, FET seems to offer a greater potential for complete treatment at the prize of a higher rate of post-operative paraplegia.
