In recent years, coil embolization of cerebral aneurysm has been widely performed as a method of endovascular treatment. Therapeutic effect tends to be insufficient when coils are placed in biased position in the aneurysm or blood flow in neck area is insufficiently reduced. It is considered that quantitative evaluation of therapeutic effect of coil embolization is important. Pressure changes before and after coil placement were measured by multipoint pressure measurement locally at the inside of the aneurysmal part and the vessel part near the aneurysm in the blood vessel model fabricated using PVA-H (Poly (Vinyl Alcohol) Hydrogel). Two ultra-miniature fiber-optic pressure sensors were inserted and located into the aneurysm from the outside of the model. Two commercially available pressure sensors were also connected to both upstream and downstream sides of the model, respectively. Pressure change in the aneurysm in accordance with the number of the coils could be measured. (137words)
