title: Value of clinical screening for detection of asymptomatic hemodialysis vascular access stenoses.
abstract: Measurement of recirculation and intradialytic venous line pressures may aid in the detection of hemodialysis vascular access stenoses. The authors screened 29 consecutive asymptomatic patients for recirculation values exceeding 15% or venous pressures greater than 150 mmHg. All 13 patients requiring and agreeing to angiography on the basis of the screening protocol proved to have high-grade stenoses of their vascular access outflow or inflow. Asymptomatic vascular access pathology is common. High-risk asymptomatic populations may be detected by simple screening procedures.
