Vocal cord paralysis. A latent effect of perivascular thorium dioxide
S. A. DeLuca, J. T. Rhea and A. L. Weber
The late effects of thorium dioxide (Thorotrast) in the perivascular space
of the neck are reviewed. The roentgenographic analysis of the problem
consists of both plain films (to detect the residual density of
extravasated thorium dioxide) and computed tomography (to help define any
involvement of the carotid artery).
