I want to know if there are any units who are utilizing ultrasound for monitoring and surveillance of the access (AVF or AVG). This can be ultrasound guided cannulation, Doppler studies, or quick views to check for stenosis or thrombus. If there are any persons who know of this I would like to be in contact with them. They can e-mail me, Candice Halinski, directly to my work email at : chalinski@nshs.edu
