Summary

the long term survival of the chronic kidney disease (CKD) patients depends on the adequacy of dialysis via good vascular access. the arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis. pre-operative evaluation and periodic monitoring of the AVF after creation with well-defined applied criteria by color doppler ultrasound (CDUS) will help to reduce rate of access failure and achieve better cumulative patency rate of fistulas.

Conditions

  • Doppler Ultrasound in Arteriovenous Fistula Preoperative Evaluation and Post-operative Periodic Monitoring

Interventions

DIAGNOSTIC_TEST

doppler ultrasound

Doppler ultrasound evaluation of AVF: * pre-operative evaluation: venous system (patency of central veins and deep venous system, patency of superficial veins, the latter diameter, depth form skin surface, distance from nearby artery, any sizable adjacent tributaries), and arterial system including morphological evaluation (course, diameter, wall alterations, any stenoocclusive disorders) and functional evaluation (flow volume and ability to dilate) * post-operative evaluation: anastomotic site (type of anastomosis, patency, diameter, PSV and any other morphologic alterations), inflow afferent artery (diameter, PSV and flow volume), outflow efferent vein (patency, diameter, color flow, spectral waveform) * the first post-operative sonographic evaluation will be done after removal of stiches from the wound and periodic monitoring every one week up until completion of 6 weeks
