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.

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).

Inclusion Criteria:

• Age from 28 to 81.
• Both sexes.
• Patients with the presence of an autogenous arteriovenous fistula (AVF) and a minimum hemodialysis treatment duration of six months.

Exclusion Criteria:

• 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.

A prospective cohort study enrolled 59 chronic hemodialysis patients of both sexes with autogenous arteriovenous fistula (AVF).
