The watershed program offers technical assistance to watershed groups, municipalities, and individual citizens. A watershed is a geographic area of land across which water, and the sediments and dissolved materials it contains, flow on their way to a single common outlet -- a stream, lake or river.
What is Lumboperitoneal Shunt? Lumboperitoneal (LP) shunt is an artificial connection created by neurosurgeons which allows excess of cerebrospinal fluid to leave the subarachnoid space and enter the peritoneum. From there, the fluid is easily absorbed and eliminated via the circulatory system and the kidneys.
Types of CSF Shunt Valves. There are two types of CSF shunt valves: fixed and adjustable. Fixed shunt valves allow CSF fluid to drain when CSF pressure exceeds a certain âfixedâ threshold. Adjustable shunt valves allow for changes to the amount of fluid that flows through the valve.
