Posterior flank approach to the peritoneum for ventriculoperitoneal shunting.
We report a technique for insertion of a distal shunt catheter into the peritoneal cavity through a posterior incision. This has been helpful in patients with impaired access anteriorly. It may also be useful in elective situations. We have performed this procedure on 3 infants where the traditional anterior approaches would have been difficult due to subcutaneous scar tissue, ostomy sites and anterior intra-abdominal adhesions. This technique was safe and provided easy access to the peritoneal cavity. Complications would be similar to those for the standard ventriculoperitoneal shunts including bowel perforation, damage to the kidney or liver, infection and occasionally posterior cervical webbing that may cause pain locally or pull the head into an extended position.
