Background and Objectives：To evaluate the feasibility and the short- and mid-term follow-up outcomes of endovascular stent-graft implantation in patients with Stanford type B aortic dissection. Subjects and Methods： Twenty-eight patients with Stanford type B aortic dissection were evaluated. An aortogram was performed immediately after the procedure and a follow-up computed tomography (CT) scan was performed within one week, between 3 and 6 months, and annually thereafter. Clinical status was also evaluated at the same time. Results：Endovascular stent-graft implantation at the target site was successful in 27 patients (96.4%). There were primary endoleaks in 6 patients and one case of procedure failure owing to migration of the stent-graft; and no procedurerelated mortality. The number of patients with early complications requiring treatment was 2 (2/27, 4%). Fourteen patients experienced postimplantation syndrome (14/27, 52%). The average follow-up period was 22.1±17.5 months. Complete resolution or thrombosis of the false lumen was achieved in 14 patients and partial thrombosis was achieved in 10 patients. Operative treatments were required in three patients due to a progressing dissection or new dissection. There were no deaths and no instances of aneurysm or aortic rupture during the follow-up period. Conclusion：Endovascular stent-graft implantation for Stanford type B aortic dissection is a feasible, safe, and effective treatment modality. All patients who underwent surgery had a persisting leak. Therefore, regular evaluation of the aortic dissection and management of endoleaks were crucial for a favorable outcome in endovascular stent-graft implantation for a Stanford type B aortic dissection.
