Analysis of influencing factors of aneurysmal dilatation of arteriovenous fistula in maintenance hemodialysis patients
Objective To investigate the incidence of aneurysmal dilatation of arteriovenous fistula(AVF)in maintenance hemodialysis(MHD)patients,and to explore the related factors affect-ing the occurrence of aneurysmal dilatation.Methods The incidence of AVF rumen-like dilatation in MHD patients was 24.82％.A total of 141 patients who received MHD treatment in the Hemodialysis Center of the Second Hospital of Shanxi Medical University from January 2021 to June 2021 and had complete clinical data were selected as the study subjects.The data were collected by consulting the hospital medical record system and outpatient hemodialysis information system.The patients were di-vided into aneurysmal dilatation group and non-aneurysmal dilatation group according to the aneurysmal dilatation criteria agreed by vascular access experts in China.The differences in the general clinical data,vascular ultrasound data and laboratory parameters between the two groups were compared.Mul-tiple logistic regression model was used to analyze the influencing factors of aneurysmal dilatation in ar-teriovenous fistula(AVF)in MHD patients.Results Compared with the non-aneurysmal dilatation group,the dialysis age,systolic blood pressure,diastolic blood pressure,cephalic vein diameter,and brachial artery blood flow were higher,while the serum albumin level and body mass index(BMI)were lower in the aneurysmal dilatation group,and the differences were statistically significant(all P＜0.05).The results of multiple logistic regression analysis showed that higher dialysis age and higher brachial artery blood flow were risk factors for AVF aneurysmal dilatation,while higher serum albumin was a protective factor for AVF aneurysmal dilatation(all P＜0.05).Conclusions Improving nutri-tional status,controlling fistula blood flow during surgery,and avoiding excessive blood flow while en-suring adequate blood flow can reduce and delay the occurrence of AVF aneurysmal dilatation in MHD patients.
