The changes of transcranial sonography in end‐stage renal disease with restless legs syndrome / 中华超声影像学杂志

ABSTRACT

Objective To discuss the neuroimaging characteristics of transcranial ultrasound in end‐stage renal disease ( ESRD ) with restless legs syndrome . Methods T ranscranial sonography ( TCS ) was performed in ESRD with restless legs syndrome ( RLS + group , n ＝ 41 ) ,ESRD without restless legs syndrome ( RLS － group , n ＝57) and control group ( n ＝47) ,w ho were enrolled in the Second Affiliated Hospital of Soochow University from January 2017 to December 2018 . T he differences of the neuroimaging characteristics of TCS in substantia nigra ( SN ) ,brainstem raphe ( BR) and red nucleus ( RN ) among the three groups were analyzed . Results T he rate of SN hypoechogenicity was significantly higher in RLS +group ( 36 .6% ,15/41) than that in RLS － group ( 19 .3% ,11/57) and control group( 8 .5% ,4/47) ( χ2 ＝10 .6 ,P＜0 .05) . T he rate of abnormal BR echogenicity was significantly higher in RLS + group ( 34 .1% , 14/41) and RLS － group ( 29 .8% ,17/57) than that in control group( 10 .6% ,5/47) ( χ2 ＝7 .7 , P ＜0 .05) . T he rate of RN hyperechogenicity was significantly higher in RLS + group ( 51 .2% ,21/41 ) than that in RLS － group ( 21 .1% ,12/57) and control group ( 10 .6% ,5/47) ( χ2 ＝19 .8 , P ＜0 .05 ) . Between RLS+and RLS － groups ,when SN ,BR and RN were all of positive performance ,the accuracy of diagnosing RLS+ reached 70% ( 7/10 ) . Conclusions The echogenicity changes of SN ,BR and RN on TCS could provide valuable neuroimaging information for the clinical diagnosis and treatment of ESRD with restless legs syndrome .
