Ventriculoperitoneal (VP) shunts are one of the most common neurosurgical procedures performed. They have been associated with a long list of problems and complications. Here, we have described an unusual and a new complication, which we recently encountered.
A 60-year-old obese male patient underwent a programmable shunt insertion for normal pressure hydrocephalus (NPH). The peritoneal end was inserted via a right upper abdominal incision. The postprocedural period was uneventful, and the patient was discharged on the second postoperative day. He was doing well and sutures were removed on the tenth postoperative day in the outpatient clinic. The same evening, he developed cerebrospinal fluid (CSF) leak from the abdominal wound and came back to us the next morning. He had an active CSF leak from the suture site, and there was a diffuse bulge at the site of the abdominal wound. Plain computed tomography (CT) abdomen was done to determine the position of the peritoneal end. In the CT, the lower end appeared to be intra-peritoneal but was lying coiled up within a cystic fluid collection [Figure 1].

The general surgical team was consulted, and he was taken up for diagnostic laparoscopy the same day. On initial exploration, the peritoneal cavity looked intact with no signs of the tube or an obvious entry point in the ventral wall.
On closer examination, the falciform ligament appeared to be bulging on one side. The bulge also corresponded with the shunt entry site. The ligament was opened, and the tube was seen coiled inside along with a fluid collection. The tube was uncoiled and placed below the diaphragm [Figure 2]. The patient did well and was discharged the next day.

The falciform ligament is a fold of peritoneum containing fat and extends from the umbilicus up to the left lobe of the liver. Its superior surface lies in contact with the posterior sheath of the right rectus muscle near the midline. It can be as broad as 5 cm in some subjects.
There has been no previous report of the tube being positioned inside the falciform ligament. Some recent publications have shown the usefulness of laparoscopy for treating abdominal complications of VP shunts. A recent publication has also suggested using laparoscopy routinely in all cases so as to reduce distal end complications.
Although some surgeons do use the trocar for abdominal end insertion, most surgeons still prefer the open method with a subcostal incision. If the abdominal end shunt insertion is being done on the right side, care must be taken to make the entry site either lateral to the rectus sheath or near its lateral border so as to avoid the falciform ligament.
