OBJECTIVE: To retrospectively evaluate early and mid-term results of thoracic endovascular repair (TEVAR) of type B aortic dissection by the second generation of stent graft.
METHODS: From January 2009 to January 2013, 383 acute, 43 sub-acute and 152 chronic patients with type B aortic dissection underwent TEVAR in our aortic center. The mean follow-up period was (27 ± 14) months. All clinical data were analyzed with SPSS 17.0.
RESULTS: The 30-day mortality and morbidity were 0.35% and 1.2% respectively. The mid-term mortality and morbidity were 0.35% and 5.5%. Serious complications included retrograde type A dissection (n = 3), new tear at the distal end of stent (n = 26), endoleak (n = 3) and paraplegia (n = 0). The retreatment rate was 5.2% ( 6 patients were transformed to open operation and 24 patients underwent re-intervention).
CONCLUSIONS: The early and mid-term results of thoracic endovascular repair (TEVAR) of type B aortic dissection by the second generation of stent graft showed lower mortality, no paraplegia and significant reduced endoleaks in comparison with the first generation stent graft. The new distal tear caused by the stent graft became the major complication. The design of the stent graft still need improvement.
