Abstract:
Objective To observe the value of contrast-enhanced ultrasound(CEUS)for evaluating DeBakey Ⅰ aortic dissection involved renal artery.Methods Totally 137 patients with DeBakey Ⅰ aortic dissection involved renal artery were retrospectively enrolled,including 132 cases involved unilateral and 5 cases involved bilateral renal arteries.The opening of totally 274 renal arteries in bilateral kidneys were observed.Taken CT angiography(CTA)as reference standard,the renal artery opened in true lumen was considered as unaffected,while opened in false lumen or true-false lumen were both considered as affected.Relative CEUS manifestations were observed,and their value for evaluating involved renal artery or not were analyzed.Results CTA showed that 132 renal arteries opened in true lumens,90 opened in false lumens and 52 opened in true-false lumens.CEUS diagnosed 131 renal arteries opened in true lumens,111 opened in false lumens and 32 opened in true-false lumens,and the sensitivity for diagnosing DeBakey Ⅰ aortic dissection involved renal artery was 90.84％,81.08％and 90.63％,respectively.The consistency between CEUS and CTA for evaluating renal artery opened in true lumen or false lumen was good(Kappa=0.786).Logistic regression analysis showed that the time to peak(TTP)and peak intensity(PI)of time intensity curve(TIC)were both impact factors for differentiating renal artery opened in true lumen or false lumen,as well as true lumen or true-false lumen(both P＜0.05),while the area under the curve(AUC)of TIC was impact factor for differentiating renal artery opened in true lumen or false lumen(P＜0.05).The AUC of receiver operating characteristic curve of the combination of TTP,PI and AUC of TIC for differentiating renal artery opened in true lumen or false lumen,true lumen or true-false lumen and false lumen or true-false lumen was 0.703,0.686 and 0.493,respectively.Conclusion CEUS was helpful for evaluating DeBakey Ⅰ aortic dissection involved renal artery.
