| Popis: | Steal phenomenon after upper extremity hemodialysis access is a clinical diagnosis and consists of signs and symptoms ranging from pain during dialysis to tissue loss. Duplex ultrasonography of the access site and limb arterial perfusion often serves as an adjunct to the diagnosis but can have limitations and there is no specific duplex measurement that indicates that an intervention will be a success. We have used hand acceleration time (HAT) to assess perfusion in a number of trauma and shock cases and hypothesized that this approach could also be beneficial in assessing patients with hemodialysis access–induced distal ischemia (HAIDI), both for identifying patients who are candidates for intervention and to measure whether the intervention will be successful. Specifically, we hypothesized that a HAT 100 ms. One patient with soft tissue sloughing was managed with banding of the proximal fistula, and 3 had proximalization of the fistula. All 4 achieved HAT |
