Monitoring and surveillance of the hemodialysis vascular access

The physical exam, the clinical assessment, along with the surveillance tool we use has provided us the ability to identify access problems or potential problems. Abnormal surveillance data is always correlated with physical exam and clinical findings to determine the need for intervention. Monitoring and surveillance of vascular access are an integral part of the care of the hemodialysis patient. There are different techniques and methods available for identifying access dysfunction. Despite multiple studies that have been performed, there is still no consensus as to the best methodology to use. Physical exam and clinical evaluation remain key in detecting access problems. This along with a surveillance method chosen by the clinic can provide early identification of stenosis allowing for timely intervention of access dysfunction.
