Abstract:
Objective:To explore the predictors and reasons for restenosis in patients with Takayasu′s arteritis(TA) involved renal artery after plain old balloon angioplasty(POBA).Methods:The clinical data of 47 TA patients (47) with renal artery admitted to Xuanwu Hospital, Capital Medical University from January 2014 to December 2020 were analyzed, including 12 man and 35 female. The age ranged from 21 to 43 years old, with an average of (28.52±10.78) years old. All patient were diagnosed as TA and underwent POBA. The patients were divided into restenosis group ( n=18) and non-restenosis group ( n=29). The patients were followed up at 1, 3, and 6 months after surgery, and after 6 months, the patients were followed up every 6 months. All patients were followed up from 36 to 108 months.The basic clinical data of the two groups were compared, and the length of stent and residual stenosis were also compared. Measurement data were expressed as ( ± s), and t-test was used for comparison between groups. Counting data were expressed as the number of cases and percentage, and comparison between groups was analyzed using the chi-square test. Multivariate Logistic regression model was used to analyze the independent risk factors of restenosis after balloon dilation, and the OR value and 95% confidence interval were calculated. Logistic regression model was used to analyze the independent risk factors for restenosis after balloon dilation. Results:All patients received POBA and operation was successfully. Restenosis was found in 18 patients, and 29 patients remained normal during the follow-up. The primary patency rate was 61.7%. Multivariate Logistic regression analysis showed that HDL-C and lesion length were the influencing factors of restenosis after POBA in TA of renal artery. The serum HDL-C level was significantly lower and the lesion was significantly longer in restenosis group than in non-restenosis group ( P<0.05). The proportion of residual stenosis>20% was higher in restenosis group than in non-restenosis group ( P>0.05). Conclusion:Serum HDL-C level, lesion length may be may be independent influencing factors of restenosis after plain old balloon angioplasty in TA of the renal artery restenosis.
