Primary outcomePrimary: Change of Subclavian Flow to Normal Flow Pattern During Cuff Test — 0; 2 participants
Summary
Subclavian steal phenomenon is normally observed in patients with stenosis of subclavian artery proximal to orifice of vertebral artery(V0). However, uremic patients undergoing hemodialysis using vascular access in the arm or forearm may also develop dialysis associated steal syndrome(DASS).For patients with symptomatic subclavian steal phenomenon, the treatment for these two groups is different. The investigators want to see if the investigators can use noninvasive duplex examination instead of invasive conventional angiography to do the differential diagnosis.
