OBJECTIVE: To compare the clinical therapeutic results of percutaneous transluminal stenting between patients with acute and chronic aortic dissections.
METHODS: From May 2002 to October 2007, 42 patients with acute type B aortic dissection and 40 patients with chronic aortic dissection underwent stenting. The clinical data of the patients were analyzed.
RESULTS: Comparing with the chronic aortic dissection group, the acute aortic dissection group had higher percentage of pleural effusion (16.7% vs 0, P =0.01) and visceral/leg ischemia (23.8% vs 2.5%, P = 0.01). The acute aortic dissection group had higher complications in early term (38.1% vs 15.0%, P = 0.02). All patients were followed up for an average of (18.7 +/- 17.3) months. The rate of complications were higher in the patients with acute aortic dissection than those with chronic aortic dissection (21.4% vs 5.0%, P = 0.03). Kaplan-Meier analysis showed no difference of survival rate between the 2 groups during follow-up period (P = 0.38). The 5-year survival rate was 90.0% in acute aortic dissection group years and 92.5% in chronic aortic dissection group, respectively. The event-free survival rate was higher in the patients with chronic dissection than that with in the patients acute aortic dissection (P = 0.04).
CONCLUSIONS: Percutaneous transluminal stenting is effective in the treatment of type B aortic dissection, but there are more complications in acute than in chronic aortic dissection group.
