TL;DR: Early thrombosis was found to be associated with female gender, forearm AVF, smaller arterial size, draining vein diameter of 2 to 3 mm, and protamine use, and Paradoxically, diabetes and stiff, noncompliant feeding arteries were associated with a lower frequency of ET.
Journal ArticleDOI

Michelle L. Robbin,Tom Greene,Alfred K. Cheung,Michael Allon,Scott A. Berceli,James S. Kaufman,Matthew B Allen,Peter B. Imrey,Milena Radeva,Yan-Ting Shiu,Heidi Umphrey,Carlton J. Young +11 more
TL;DR: Two-week measurements at 2 weeks may be of value in the early identification of fistulas that are unlikely to develop optimally in a multicenter hemodialysis fistula maturation study.
Journal ArticleDOI
A triple-targeted ultrasound contrast agent provides improved localization to tumor vasculature
TL;DR: An evaluation of multitargeted microbubbles is summarized, comparing single‐, dual‐, and triple‐targeted motifs to improve contrast‐enhanced sonography of tumor angiogenesis.
Journal ArticleDOI
