Ultrasound Evaluation of Vascular Access Used in Hemodialysis
The purpose of this study is to develop and perfect a method to examine and follow-up vascular access by a non-invasive technique. Ultrasonographically appears as the ideal approach to this problem. High-frequency, short focused transducers in combination with improven signal processing and display considerably enhance the feasibility of study. Like superficially located vascular structures, bovine grafts and cannular arteriovenous shunts can be easily demonstrated sonographically. We report our preliminary experience with 24 cases. We plan to base our final results on a minimum of 100 cases, hopefully with occasinal radiographic documentation.
