The patient was operated by me three weeks ago for non-functioning LPS inserted in Iraq for pseudotumor cerebri. At that time it was found that the proximal end was not inserted properly and it was reinserted intrathecally. So as not to violate the intraperitoneal cavity, I used the old channel to pass the peritoneal end and it went easily. Later the last week, the patient noticed accumulation of fluids in the right flank. She was asked to come back and the CSF pocket was seen and she was reoperated to reinsert properly the distal end in the peritoneal cavity. The lesson from here is: Don't use the pass of an old nonfunctioning shunt. Do it de novo. |
