Background— Studies of aortic aneurysm patients have shown that the risk rupture increases with size. However, few studies acute dissection and size exist. We used data from our registry to better understand relationship between diameter type A dissection. Methods Results— examined 591 enrolled in International Registry Acute Aortic Dissection 1996 2005 (mean age, 60.8 years). Maximum diameters averaged 5.3 cm; 349 (59%) had <5.5 cm 229 (40%) <5.0 cm. Independent predictors at smaller (<5.5 cm) included a history hypertension (odds ratio, 2.17; 95% confidence interval, 1.03 4.57; P =0.04), radiating pain 2.08; 1.08 4.0; =0.03), increasing age 1.03; 1.00 1.05; =0.03). Marfan syndrome were more likely dissect larger 14.3; 2.7 100; =0.002). Mortality (27% patients) was not related Conclusions— The majority present thus do fall within current guidelines for elective surgery. other than measurement ascending aorta are needed identify
