Blind or Seldinger Technique

In the blind or modified Seldinger technique, a needle is inserted into the abdomen, a guidewire placed, a tract dilated, and the catheter inserted through a split-sheath; all maneuvers are performed without visualization of the peritoneal cavity (11). The deep cuff usually remains outside the outer rectus sheath after implantation. The blind technique is not widely used in the United States. The bedside blind insertion technique is associated with a significant risk of visceral damage and high rate (31%) of subsequent migration leading to failed dialysis (12). The other disadvantage is that final catheter placement cannot be controlled, and it is not suitable for the placement of "complex" catheters.
