How do doctors check for fistulas?
Outflow stenosis can best be detected by an abnormal arm elevation test. In a normal fistula or graft, having the patient raise their arm should allow venous collapse and flattening of the fistula; if there is significant outflow stenosis the fistula may remain plump with arm elevation.
How is outflow stenosis diagnosed in fistula?
Right after fistula creation, if you feel your fistula, you should notice a vibration coming from your access site. This vibration is called a thrill. Over the next week, the thrill should get stronger. This is normal and means your access is healing and maturing as it should.

How do you palpate AV fistula?
Palpation. The AVF should be systematically palpated from the arterial to the venous end. A pulsatile AVF suggests a stenosis in the outflow segment. Pulsatile immature AVFs should not be cannulated as they form significant hematomas when the HD needles are removed due to high intra-access pressure.
How do you assess fistula patency?
Assess for patency at least every 8 hours. Palpate the vascular access to feel for a thrill or vibration that indicates arterial and venous blood flow and patency. Auscultate the vascular access with a stethoscope to detect a bruit or "swishing" sound that indicates patency.

All of these work differently but your nurse will explain how if you want to understand more details. However, all of the above estimate how well your fistula is working by assessing the blood flow rate through the fistula and whether there is any obstruction causing recirculation (when the dialysed blood from the venous or top needle flows back towards the arterial or lower needle). If this investigation raises any concerns, the nurse will explain this and you will be referred for further investigations of your fistula blood flow rates.

What is an elevation test for fistula?
The arm elevation test is a simple method to diagnose outflow vein stenosis. Under normal circumstances, when the fistula arm is raised above the level of the heart, the fistula will collapse. If an outflow stenosis is present, the area of the fistula distal to the stenosis will remain distended. Note: this test works best with forearm AVFs and is not valid for AVGs. Patients can be taught to perform the arm elevation test as a way to self-monitor their AV accesses. (Click here for a video demonstration of the arm elevation test.)

Which hand is occluding in sequential occlusion test?
Figure 12. The sequential occlusion test. The left hand (occluding hand) gradually moves farther from the right hand (palpating hand), assessing the pulse each time the access is occluded. If the access is occluded distal to a collateral vein, the thrill will stop and the pulse will intensify (A). If the access is occluded proximal to the collateral vein, the thrill will continue and no pulsation will be felt (B). From Salman and Beathard, CJASN, 2013
What is pulse augmentation test?
The pulse augmentation test is used to evaluate the inflow. The AV access is completely occluded several centimeters above the arterial anastomosis with one hand, while the other hand is used to assess the quality of the pulse. Increased pulse intensity (augmentation) with occlusion of the outflow vein is a normal finding. Failure of the pulse to augment when the outflow vein is occluded suggests the presence of inflow stenosis.
