Estudio paramétrico de catéteres ventriculares: Tesis Doctoral Internacional
Parametric study of ventricular catheters for hydrocephalus Abstract Background: To drain the excess of cerebrospinal fluid in a hydrocephalus patient, a catheter is inserted in one of the brain ventricles, and then connected to a valve. This so-called ventricular catheter is a standard-size, flexible tubing with a number of holes placed symmetrically around several transversal sections or “drainage segments”. Three-dimensional computational dynamics shows that most of the fluid volume flows through the drainage segment closest to the valve. This fact raises the likelihood that those holes and then the lumen get clogged by the cells and macromolecules present in the cerebrospinal fluid, provoking malfunction of the whole system. Objective:…
