Overdrainage and the guessing game
Hawke has had some rough days recentlly; We are in prayer weather we need to head to nuerosurgery today . . .praying for discernment and th anking all of you for your prayers and love! Seems like his overdrainage won't stop, based upon the symptoms we are seeing and this past month. Based on some nuersurgery articles we are reading finding a shunt that works may be like a crap-shot?
"The major contributor to recurrent malfunction is the development of very small or slit-like ventricles and chronic shunt overdrainage. Although overdrainage seems to occur in most patients shunted in childhood, it is the development of craniocerebral disproportion that is the primary underlying pathophysiology."

"None of the particular valve designs that have been used clinically has eliminated the phenomenon of chronic overdrainage. Some designs seem to allow overdrainage at a slower rate, but all of them eventually allow the ventricles to become smaller and smaller, thus setting up the potential for craniocerebral disproportion and the development of the slit ventricle syndrome (SVS). The definition of SVS has been characterized in numerous ways. It is probably best stated as repeated, intermittent symptoms of shunt malfunction in a patient who seems otherwise healthy. It is characterized by headaches, varying degree of lethargy, and may or may not be associated with nausea or vomiting"

Carmen found this link today; its sounds near identical what Hawke may or may not have; we are praying for disernemtn and healing!
