PURPOSE: We describe the long-term efficacy of early entry closure for acute type B aortic dissection by open stent grafting based on long-term results and changes in the false lumen on enhanced computed tomography (CT). METHODS: We performed open stent grafting for acute type B aortic dissection in 28 28 patients between 1998 a 2008. They included 14 patients with complicated type B aortic dissection (11 patients with limb and/or visceral ischemia and 4 patients with impending rupture). Uncomplicated type B aortic dissection was present in 14 patients, including 4 patients with an ulcer-like projection and 10 patients who had stable dissection with a patent false lumen. RESULTS: Two patients who had the ischemic type died within 30 days. Postoperative complications occurred in two patients, including one case of paraplegia and one of mediastinitis. Two more deaths occurred during a median follow-up period of 45 months (range 6-114 months), with one related to open stent-graft infection and one due to pneumonia. The overall survival rate 5 years after open stent grafting was 77%. According to follow-up by CT, the false lumen was completely thrombosed and obliterated in all 26 patients with stent grafts. CONCLUSION: Early entry closure for both complicated and uncomplicated acute type B aortic dissection with an open stent graft has an acceptable early outcome and provides a high aortic remodeling rate.
