  • Title: Peritoneal catheter knot formation in ventriculoperitoneal shunting: an intraoperative artificial phenomenon?
    Author: Hori YS, Ebisudani Y, Umakoshi M, Aoi M, Fukuhara T.
    Journal: Childs Nerv Syst; 2018 Jan; 34(1):31-33. PubMed ID: 29086001.
    Abstract:
    BACKGROUND: Peritoneal catheter knot formation is a rare complication associated with ventriculoperitoneal shunting. In most reports, the knot formation was also considered to be the cause of shunt malfunction. DISCUSSION: In this study, we demonstrate the possible misinterpretation of peritoneal catheter knot formation in ventriculoperitoneal shunting. We found a knot in the peritoneal catheter intraoperatively, while no knot was noted on the abdominal X-ray taken 1 day prior to the operation. Our findings indicate that the knot had actually formed intraoperatively. This case suggests that we should not immediately conclude that a knot is the cause of shunt malfunction in such an operation.
