ABSTRACT
To investigate the clinical diagnostic value of ultrasonographic superb micro‐vascular imaging ( SM I) for abdominal branch arteries′involvement in Stanford B aortic dissection ( AD ) . Methods A total of 34 AD patients underwent conventional ultrasound ,SMI and CTA . The characteristics of the ultrasonographic images of branch artery involvement including coeliac artery ,superior mesenteric artery ,left and right renal artery were analyzed . T he diagnostic performance of conventional ultrasound and SM I were compared and CT A was used as the reference standard . Results Among the 34 patients with AD ,according to the ultrasonographic images′characteristics ,136 branch arteries were categorized into four classesClass Ⅰ (81/136) ,branch artery perfusion supplied from the aortic true lumen ; Class Ⅱ ( 27/136) , dissection extending into the branch ; Class Ⅲ ( 16/136 ) ,branch artery perfusion supplied from the aortic false lumen ; Class Ⅳ ( 12/136) ,branch artery perfusion supplied from the aortic true and false lumens . T he diagnostic accordance rate of the conventional ultrasound and SM I were 76 .5% ( 104/136 ) and 92 .6%( 126/136) and had significant differences ( P <0 .001) . Conclusions SMI can be used to evaluate branch artery involvement in AD patients w hich will guide the practice of pre‐operation and post‐operation .
