简要总结
This study aimed to detect the possibility of using venous pressure as a predictor for high flow access as a simple, non-invasive screening technique in hemodialysis patients.
详细描述
The patient's vascular access is often referred to as their "lifeline," and without it, the life-sustaining treatment of hemodialysis would not be possible. To maintain access, patency depends on accurate diagnosis and timely, active interventions.
The Kidney Disease Outcomes Quality Initiative (K/DOQI) recommends native arteriovenous fistula (AVF) as the vascular access of choice for hemodialysis due to its longevity, lower complications, and lower mortality rate compared to catheters.
Currently, K/DOQI guidelines suggest that high intra-access pressure may be regarded as a surrogate for arteriovenous fistula (AVF) outflow stenosis. It can be measured using static venous pressure (sVP) or standardized dynamic venous pressure (dVP).

入选标准
- •Age from 28 to
- •Both sexes.
- •Patients with the presence of an autogenous arteriovenous fistula (AVF) and a minimum hemodialysis treatment duration of six months.
排除标准
- •Physical examination revealed signs of AVF outflow stenosis, including localized edema, collateral circulation, hyperpulsatile fistula characteristics, or a positive hand elevation test.
- •If ultrasound confirmed AVF stenosis or thrombosis, or angiography identified central venous stenosis or thrombosis in clinically suspected cases.
结局指标
主要结局
Static venous pressure
时间窗: 6 months post-procedure
Static venous pressure (SVP) were measured with the blood pump deactivated through direct intra-access measurement via the venous outflow cannulation needle. Blood pressure (BP)-adjusted values were calculated using the patient's mean arterial blood pressure (MAP) recorded contemporaneously with venous pressure measurements.
次要结局
- Standardized dynamic venous pressure(6 months post-procedure)
- Arteriovenous fistula flow(6 months post-procedure)
- Urea reduction ratio(30 minutes following treatment completion)
