Purpose: To report an investigation of a purely endovascular procedure to address access-induced hand ischemia in dialysis patients. Case Report: Two dialysis patients presented with stage III steal syndrome consisting of severe pain and numbness in their fingers. Preoperative fistulograms distal to the anastomosis showed alternating antegrade and retrograde flow. Under ultrasound guidance, the fistula was accessed and a 4-F micropuncture sheath placed. An angled guidewire was then advanced proximally into the brachial artery. A 6-F short sheath with marker was placed followed by a 4-F straight guide catheter inserted into the proximal brachial artery. A 9-F Flair endovascular stent-graft was advanced over a 0.035-inch stiff angled Glidewire into the fistula just distal to the arterial anastomosis and deployed. Postoperatively, pain and numbness resolved in both patients immediately. Postoperative fistulograms documented antegrade flow. Access flow velocity readings decreased significantly and pulse oximetry readings increased significantly in both patients, who were followed for >6 months with no reported complications. Conclusion: These 2 cases suggest that this endovascular approach to access-induced hand ischemia may be a viable alternative to open/hybrid surgery.
