大动脉的尺寸索引到的 Unreliability 与特纳一起在一个病人预言大动脉的解剖的风险症候群

Aortic size index(ASI) has been proposed as a reliable criterion to predict risk for aortic dissection in Turner syndrome with significant thresholds of 20-25 mm/m2. We report a case of aortic arch dissection in a patient with Turner syndrome who, from the ASI thresholds proposed, was deemed to be at low risk of aortic dis-section or rupture and was not eligible for prophylactic surgery. This case report strongly supports careful monitoring and surgical evaluation even when the ASI is < 20 mm/m2 if other significant risk factors are present.
