Fluoroscopy is a widely accepted method for the insertion and positioning of cuffed dialysis catheters, because it is easy to use, accurate and reliable, and has a relatively low incidence of complications. The purpose of our study was to evaluate the feasibility of tunneled hemodialysis catheter placement without the use of fluoroscopy but with a dynamic ultrasound-imaging-based guided technique.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>From January 2015 to December 2017, we performed an observational prospective cohort study of 56 patients with end-stage renal disease who required tunneled dialysis catheter placement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The overall success rate for ultrasound-guided central access was 100%, with a mean number of 1.16 (\u00b10.4) attempts per patient. There were no incidences of guide wire coiling\/kinking, carotid puncture, pneumothorax, or catheter malfunction. Catheter flow during dialysis was 286 (\u00b138) mL\/min. The total number of catheter days was 7451, with a mean of 133\u2009days and a range of 46\u2013322\u2009days. Life table analysis revealed primary patency rates of 100%, 96%, and 53% at 30, 60, and 120\u2009days, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Dynamic ultrasound-based visualization of microbubbles in the right atrium is a highly accurate method to detect percutaneous implantation of large-lumen, tunneled, central venous catheters without the need for fluoroscopic guidance technology.
