Another potential problem is that the latex
may not expand the vessel to its maximal diameter,
particularly if the vessel is partially
contracted. Papaverine was utilized to standardize
all vessels at maximal dilation and to
enhance conditions for filling. Because of
media viscosity and the absence of vascular
tone, aortic pressures meaningful for supply of
blood (Berne and Levy, 1977) may be particularly
misleading if applied during injection of
Vultex. In using papaverine and microscopy in
