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.
ABSTRACT
Objective@#To investigate the effect of endovascular treatment of cerebral infarction with right aortic arch and Kommerell's diverticulum.@*Methods@#Retrospective analysis was done to assess the treatment effect of a case from vascular surgery, Xuanwu Hospital of Capital Medical University. This case was diagnosed as cerebral infarction with right aortic arch and Kommerell's diverticulum.@*Results@#One month after the treatment of cerebral infarction, we successfully used the thoracic aortic stent to isolate the Kommerell's diverticulum. There were no operative complications occurred. The stent had good shape and smooth blood flow was seen in the stent.@*Conclusions@#Endovascular treatment to cerebral infarction with right aortic arch and Kommerell's diverticulum is safe and feasible, and the clinical outcome requires further long-term follow-up.

ABSTRACT
Endovascular aortic repair (EVAR) has been the main treatment means for abdominal aortic aneurysm.It has become an expert consensus that in the case of abdominal aortic aneurysm that is complicated by iliac aneurysm,the preservation of internal iliac artery is necessary because it can prevent the occurrence of gluteal muscle ischemnia,sigmoid ischemia,male sexual dysfunction and other complications.In recent years,with the continuous updating of the endovascular devices it has become possible to retain the internal iliac artery in the performance of EVAR.At present,the reconstruction of internal iliac artery in EVAR includes a variety of techniques,including intraluminal iliac branched device (IBD) technique,sandwich technique,common iliac artery covered-stent bell-bottom (BBT) technique,external iliac artery-internal iliac artery intraluminal shunt technique (reverse chimney technique),and spring coil embolism technique.This article aims to make a summary of all the above mentioned techniques.
ABSTRACT
Open surgery was the main treatment for abdominal aortic diseases in the past .However , with the development of endovascular instruments , endovascular repair technique has become the main option for abdominal aortic diseases .Unibody bifurcated stent-graft and modular bifurcated stent-graft are often used to treat abdominal aortic diseases .Unibody bifurcated stent-graft has its own features in endovascular repair of abdominal aortic diseases .We made a literature summary on application of unibody bifurcated stent-graft in abdominal aortic diseases .
