Brachiocephalic vein confluence stenosis treated by two Wallstents using Y technique.

Background: Patency of the central veins is mandatory for proper function of hemodialysis fistula created at the upper extremities.

Case Report: We present a case of dilatation of right brachiocephalic vein (RBCV) stenosis using a Wallstent implanted through the wall of another Wallstent, which had formerly been inserted into the left brachiocephalic vein and the superior vena cava (SVC). The left subclavian vein was subsequently permanently occluded which rendered the left upper extremity unsuitable for hemodialysis.
