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.
测量再循环和透析期间静脉管路压力可能有助于检测血液透析血管通路狭窄。作者对29例连续的无症状患者进行筛查，以寻找再循环值超过15%或静脉压力大于150 mmHg的患者。根据筛查方案，所有13例需要并同意进行血管造影的患者均被证实存在血管通路流出道或流入道的高度狭窄。无症状的血管通路病变很常见。通过简单的筛查程序可能检测出高危无症状人群。
