Ventriculoperitoneal Shunt Implantation

Ventriculoperitoneal shunt implantation technique has benefited from the use the minimal access implantation of the shunt end in the abdomen. Re-do procedures of ventriculoperitoneal shunt implantations are better performed under endoscopic vision when ad

Preoperative Considerations

Technical Notes

1. The patient is draped with the head and neck exposed on the side that the shunt is to be placed. The abdomen, however, is draped in a fashion suitable for abdominal procedures. 2. Consider rifampicin- or clindamycin-impregnated silicone shunts in complicated cases. 3. Antibiotics may be administered preoperatively. 4. Efforts should be taken to avoid hypothermia during surgery in infants. 5. The scalp is shaved at the site of intended catheter placement.

1. Care is taken to minimize handling of the shunt throughout the entire surgical procedure. 2. In the case of abdominal adhesions, two ports are introduced and the adhesions are removed using conventional laparoscopic methods. 3. Using a port (peel-away sheath) to insert the shunt in the abdomen prevents direct contact of the shunt with the abdominal skin. Use of skin foil is also recommended. 4. The scope should control the placement and flow of the shunt before closure.

42.10 Laparoscopic-Assisted Ventriculoperitoneal Shunt Implantation

Procedure Variations

1. The abdominal portion of the procedure can be performed using a 5-mm trocar and a 10-Fr introducer for camera and catheter insertion. 2. Under laparoscopic control, a needle is introduced through a 5-mm incision in the right upper quadrant and the shunt tubing is tunneled to that site. A J-tipped guide wire is introduced, and the needle is exchanged for a dilator and peel-away sheath. The shunt is delivered through the sheath, which is sectioned and removed.
