However, the flanges on the catheter frequently scarred within and tether to the choroid plexus, resulting in higher rates of intraventricular hemorrhage when removed. Today, flanged catheters are rarely encountered.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>The authors describe an illustrative case of a 7-year-old girl recently adopted from another country with a history of myelomeningocele and shunted hydrocephalus. She had been treated with a flanged catheter at birth. She presented with a shunt infection, which required removal of the flanged catheter tethered to the choroid.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>The authors illustrate the safe removal of a posterior-entry flanged ventricular catheter tethered to the choroid plexus using monopolar flexible electrocautery.
