My brother was born with hydrocephalus. As a newborn in 1964 he had a shunt put in his jugular which took the pressure off his brain where the spinal fluid was pressing on it. This was made of plastic. It remained in his jugular for many years. He is now in his late forties. It may be that some form of plastic stent will allow blood flow through the jugular or other vein without damaging the vein wall. Certainly oxygen will not get to a vein's tissue through plastic, although perhaps some gas permeable plastics (such as are used for contact lenses) exist which will be better. The more recent shunts for this purpose have a one way valve in them which is used to control backflow of spinal fluid, I think. It seems to me somebody needs to try this as a more permanent solution. Especially a person like myself, who does not have many years of life expectancy left anyway, so a 50 year guaantee is not needed.
