性别（Gender）*

请选择性别 Please select gender

1. 年龄（Age，岁/y）*

请输入有效年龄（1-120岁）Please enter valid age (1-120 years)

评分规则：>54.72岁得1分，否则0分 | Scoring Rule: 1 point if >54.72 years, 0 points otherwise

指标定义：患者当前实际年龄（精确到小数点后1位）
Definition: Patient's current actual age (accurate to 1 decimal place)
临床意义：年龄是血管功能的重要影响因素，高龄患者血管弹性下降、修复能力减弱，狭窄风险略高
Clinical Significance: Age is an important factor affecting vascular function. Elderly patients have decreased vascular elasticity and impaired repair capacity, leading to a slightly higher risk of stricture
评分依据：基于临床数据统计，54.72岁为风险分界点
Scoring Basis: Based on clinical data statistics, 54.72 years is the risk cutoff point

2. 瘘口直径（Fistula Diameter，cm）*

请输入有效直径（>0且≤2.0cm）Please enter valid diameter (>0 and ≤2.0cm)

评分规则：≤0.46cm得1分，否则0分（保护因素）| Scoring Rule: 1 point if ≤0.46cm, 0 points otherwise (Protective Factor)

指标定义：动静脉内瘘吻合口处的实际测量直径（超声检测值）
Definition: Actual measured diameter at the anastomosis of arteriovenous fistula (ultrasound detection value)
临床意义：瘘口直径适中（>0.46cm）时，血流动力学更稳定，狭窄发生率降低
Clinical Significance: When the fistula diameter is moderate (>0.46cm), hemodynamics is more stable, and the incidence of stricture is reduced
测量建议：使用超声在吻合口1cm处垂直测量，精确到0.01cm
Measurement Suggestion: Use ultrasound to measure vertically 1cm from the anastomosis, accurate to 0.01cm

3. 手术次数（Surgery Times）*

请输入有效次数（≥0）Please enter valid number (≥0)

评分规则：>0.998次得3分，否则0分（风险因素）| Scoring Rule: 3 points if >0.998 times, 0 points otherwise (Risk Factor)

查看详细说明 | View Detailed Explanation

指标定义：患者既往接受的内瘘相关手术次数（含首次手术）
Definition: Number of previous fistula-related surgeries received by the patient (including the first surgery)
临床意义：多次手术会增加血管损伤、瘢痕组织形成风险，显著提高狭窄发生率
Clinical Significance: Multiple surgeries increase the risk of vascular injury and scar tissue formation, significantly increasing the incidence of stricture
评分依据：手术次数≥1次时，风险显著升高，故赋予3分权重
Scoring Basis: When the number of surgeries ≥1, the risk increases significantly, so a weight of 3 points is assigned

4. 首次使用1年内未手术治疗（No Surgery Within 1 Year After First Use）*

请选择是否 Please select yes or no

评分规则：是得6分，否则0分（保护因素）| Scoring Rule: 6 points for yes, 0 points for no (Protective Factor)

查看详细说明 | View Detailed Explanation

指标定义：内瘘首次投入使用后，1年内未因狭窄、血栓等并发症接受手术干预
Definition: No surgical intervention for complications such as stricture and thrombosis within 1 year after the first use of the fistula
临床意义：1年内无手术史表明内瘘初始功能良好，长期通畅性更优
Clinical Significance: No surgical history within 1 year indicates good initial function of the fistula and better long-term patency
评分依据：该指标是保护因素中权重最高项，反映内瘘基础质量
Scoring Basis: This indicator is the highest weighted protective factor, reflecting the basic quality of the fistula

5. 多种基础疾病（≥2种）（Multiple Comorbidities [≥2 Types]）*

请选择是否 Please select yes or no

评分规则：是得3分，否则0分（风险因素）| Scoring Rule: 3 points for yes, 0 points for no (Risk Factor)

查看详细说明 | View Detailed Explanation

指标定义：同时患有糖尿病、高血压、冠心病、高脂血症等基础疾病中的2种及以上
Definition: Simultaneously suffering from 2 or more of the following comorbidities: diabetes mellitus, hypertension, coronary heart disease, hyperlipidemia, etc.
临床意义：多种基础疾病协同损害血管内皮功能，加速动脉粥样硬化，升高狭窄风险
Clinical Significance: Multiple comorbidities synergistically damage vascular endothelial function, accelerate atherosclerosis, and increase the risk of stricture
统计依据：合并2种以上基础疾病患者的狭窄发生率是单一疾病患者的2.3倍
Statistical Basis: The incidence of stricture in patients with ≥2 comorbidities is 2.3 times that of patients with a single disease

6. 甲状旁腺激素（Parathyroid Hormone, PTH，pg/mL）*

请输入有效数值（≥0）Please enter valid value (≥0)

评分规则：>16.53pg/mL得1分，否则0分（风险因素）| Scoring Rule: 1 point if >16.53pg/mL, 0 points otherwise (Risk Factor)

查看详细说明 | View Detailed Explanation

指标定义：血液中甲状旁腺激素的检测值（空腹静脉血检测）
Definition: Detected value of parathyroid hormone in blood (fasting venous blood test)
临床意义：PTH升高会导致血管钙化、纤维化，损害内瘘血管壁结构
Clinical Significance: Elevated PTH leads to vascular calcification and fibrosis, damaging the fistula vessel wall structure
正常范围：15-65pg/mL，超过16.53pg/mL时狭窄风险开始上升
Normal Range: 15-65pg/mL, the risk of stricture begins to increase when exceeding 16.53pg/mL
