Experimental and numerical modelling of the ventriculosinus shunt (El-Shafei shunt).
This study assesses malresorptive hydrocephalus treatment by ventriculosinus shunting with the shunt in the antegrade or retrograde position. First, an experimental model of the cerebral ventricles, the arachnoid villi, the cortical veins, and the superior sagittal sinus was built. For this purpose, the compliance of a human cortical vein was measured and then modelled by means of Penrose tubes...
متن کاملEvaluation of shunt malfunction using shunt site reservoir.
OBJECTIVE To determine the usefulness of a separate reservoir placed at the site of the shunt in evaluation of shunt malfunction. METHODS AND MATERIALS A ventricular catheter was placed alongside the proximal catheter of the shunt and connected to a subgaleal reservoir in 17 patients, in 9 a double-lumen catheter with integrated reservoir and in 13 patients a dual catheter with a double-port ...
متن کاملModelling of Three-phase Shunt Hybrid Active Power Filter
The three-phase Shunt hybrid APF topology for harmonic mitigation in low and medium voltage power distribution systems consists of a VSI based three phase shunt active filter (SAF) and tuned passive filters (TPF) connected in parallel with the load. This chapter discusses the modelling of shunt active filter and design of filter interfacing inductor, DC bus capacitor, tuned passive filters. It ...

متن کاملPortacaval shunt and hyperlipidemia.
It has been more than four years since completely diverting portacaval shunt was first performed clinically' for the purpose of lowering the serum concentration of cholesterol and low-density lipoproteins (LDL). Since then, we have treated two more patients with this method. An additional nine patients who have undergone the same procedure in other centers have been documented in the literature...
