Temporary peripheral blood filtration methods to reduce or prevent post-surgery related cognitive dysfunction

摘要

Methods are disclosed and exemplified in which a temporary intravascular filter is inserted into a vessel to trap emboli that may be released during or after a surgical procedure. Such filtering removes emboli in order to reduce or eliminate post-surgical cognitive dysfunction. In particular, the methods are directed to dealing with surgeries conducted on the limbs, and filtering in a vein that returns blood from the limb undergoing surgery. More particularly, the methods are directed to filtration during a surgery on a limb in which blood flow is restricted to the surgical field, in which cases a greater quantity of emboli are expected to be generated as a result of the surgical procedure.
