[Abstract] Objective: To investigate the influencing factors of immature autologous internal arteriovenous fistula and construct a prediction model. Method: A total of 1 001 patients with stage 5 chronic kidney disease who had established autologous internal arteriovenous fistula in Pingxiang People's Hospital from June 2016 to June 2021 were selected as the research subjects. According to whether the patients' internal fistula had mature, they were divided into mature internal fistula group (n=735) and immature internal fistula group (n=266). The clinical data of patients were collected, and the influencing factors of immature autologous internal arteriovenous fistula were analyzed by multivariate logistic regression, and a prediction model was constructed, and its predictive value was evaluated. Result: Obesity (OR=2.542), diabetes (OR=4.923), hypoproteinemia (OR=3.408), diameter of radial artery (OR=0.416), diameter of cephalic vein (OR=0.587) and C reactive protein (OR=3.487) were influencing factors of immature autologous internal arteriovenous fistula (Plt;0.05). The prediction model was constructed: Y=1/(1+e-x),
X=-2.958 + 0.933×obesity + 1.594×diabetes + 1.226×hypoalbuminemia - 0.877×diameter of radial artery -0.533×diameter of cephalic vein + 1.249×C reactive protein. The area under the ROC curve was 0.820 [95%CI (0.794, 0.846), Plt;0.001], the sensitivity was 81.55%, and the specificity was 67.26%. Conclusion: Obesity, diabetes, hypoproteinemia, diameter of radial artery, diameter of cephalic vein and C reactive protein are closely related to immature autologous internal arteriovenous fistula, the model constructed in this study has good prediction value and can be used for clinical reference.

自體動(dòng)靜脈內(nèi)瘺是終末期腎病患者血液透析的重要血管通路,相較中心靜脈置管具有感染率低、并發(fā)癥少、可反復(fù)穿刺、使用壽命長(zhǎng)的優(yōu)勢(shì),是臨床首選的血管通路[1-2]。但是,自體動(dòng)靜脈內(nèi)瘺需要等待血管重塑達(dá)到成熟標(biāo)準(zhǔn),才符合血液透析要求。臨床發(fā)現(xiàn)自體動(dòng)靜脈內(nèi)瘺成熟率為60%~80%[3],部分患者內(nèi)瘺成熟不良無(wú)法發(fā)揮正常的血管通路功能,嚴(yán)重影響血液透析質(zhì)量[4]。因此,如何預(yù)測(cè)患者自體動(dòng)靜脈內(nèi)瘺成熟不良風(fēng)險(xiǎn)具有重要的臨床意義。目前有關(guān)自體動(dòng)靜脈內(nèi)瘺成熟不良的研究較為豐富,但缺乏有效可行的內(nèi)瘺成熟不良預(yù)測(cè)模型。……
