Color Doppler Evaluation Of Hemodialysis Arteriovenous Fistulae

In conclusion, CDS is a noninvasive technique that allows theassessment of both anatomy and hemodynamics of an AVF.This technique is free of any known risk, cheap and can be used atthe bedside. CDS outlines the AVF lumen and allows definition of lumendimensions and detection of luminal encroachment. The technique alsoprovides important information to the surgeon, thereby potentiallyincreasing the number of AVF reconstruction rather than new shunts.Combined CDS and Doppler flow assessment will ultimatelybecome the ideal imaging for HD access routes. Routine serial sonographicexamination can detect complications early enough to improve fistulasurvival and decrease patient morbidity. Most major complications can berepaired without limb loss and with shunt salvage.DUS play a major diagnostic role in comprehensive evaluation ofpossible shunt complications, its possible causes and differential diagnosis.
