Abstract In conclusion, CDS is a noninvasive technique that allows the assessment of both anatomy and hemodynamics of an AVF. This technique is free of any known risk, cheap and can be used at the bedside. CDS outlines the AVF lumen and allows definition of lumen dimensions and detection of luminal encroachment. The technique also provides important information to the surgeon, thereby potentially increasing the number of AVF reconstruction rather than new shunts. Combined CDS and Doppler flow assessment will ultimately become the ideal imaging for HD access routes. Routine serial sonographic examination can detect complications early enough to improve fistula survival and decrease patient morbidity. Most major complications can be repaired without limb loss and with shunt salvage. DUS play a major diagnostic role in comprehensive evaluation of possible shunt complications, its possible causes and differential diagnosis. |
