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.
