Use of the radial artery for hemodialysis access.

Hypothesis: Under limited conditions, use of the radial artery (RA) for hemodialysis access in patients with end-stage renal disease is safe and effective.

Methods: The nondominant upper extremities of 211 consecutive patients with end-stage renal disease were evaluated with duplex ultrasonography to assess RA and ulnar artery (UA) flow contributions to their hands. Diameters and peak systolic velocities were measured in each artery, from which peak flows were calculated.

Postoperative edema after vascular access causing nerve compression secondary to the presence of a perineuronal lipoma: case report.

Objective And Importance: Median nerve neuropathy can be clinically devastating to a patient. It can be caused by compression of the median nerve anywhere along its course. We present the case of delayed median nerve neuropathy after the placement of a vascular graft in the arm.
