Objective To summarize the experience on thoracic endovascular aortic repair with JOTEC E-vita stent-grafts.Methods From February 2009 to September 2012,70 TEVARs were performed with JOTEC E-vita stent-grafs (67 men; mean age range 32~82 (57.3±10.8).Pathologies included Standford type B aortic dissection in 39, penetrating aortic ulcer combined with intramural hematoma in 25, aortic pseudoaneurysm in 2 and thoracic aortic aneurysm in 4 patients.Stent-grafts were implanted by surgical incision in 65 patients and totally percutaneous method in 5.Left subclavian artery(LSA) was covered in 11 patients due to insufficient proximal landing zone, in which 9 patients necessitated LSA chimney stent implantation.Patients with aortic coverage less than 230 mm were defined as group A (n=30) and more than 230 mm as group B(n=40).Follow-up CTA was performed at postoperative 1、 3、 6、 12 months and annually thererafter to observe whether there was endoleak or whether the lesion was excluded.Mortality and endoleak during perioperative and follow-up period were calculated.Perioperative spinal cord ischemia was compared between group A and B.Results Stent-grafts were implanted successfully for all patients with 100% technical success.Seventy-five stent-grafts were implanted for 70 patients, in which two stent-grafts were necessary in 5 cases with long pathology.Complications included difficult tapered tip withdrawal in 2; stent-graft twisting in 12; endoleak in 17 with incidence of endoleak 24.3% (17/70).There was no significant statistical difference regarding the incidence of spinal cord ischemia between group A and B.After 2~40 months follow-up, one died of Standford type A aortic dissection with follow-up mortality 1.43(1/70).Conclusion Long thoracic aortic pathology, especially penetrating aortic ulcer combined with.
