Polyvinyl alcohol particles

Macroporous polyvinyl alcohol particles with a molecular weight cutoff of ca. 8 X 10 in gel-permeation chromatography have been prepared. The particles are produced by first dispersing an aqueous solution of polyvinyl alcohol in an organic solvent to make spheres of polyvinyl alcohol solution. Holding the dispersion in such a state that a gel will then form spontaneously will cause the gel to react with glutaraldehyde in the presence of an acidic catalyst (85). [Pg.23]

Particulate embolization is an option when contrast extravasates and the bleeding branch is beyond the reach of superselective catheterization (Fig. 5.7). Non-calibrated polyvinyl alcohol particles (PVA) in sizes of 150-250 [i to 250-350 p or even larger should be used. The amount of particles should be kept as low as possible to avoid diffuse distal embolization. After each injection of 0.1-0.2 ml (up to a maximum of 1 ml) of a dilution of PVA, control arteriography should verify that the bleeding point has been... [Pg.58]
