title: [An experimental comparative study of several vasodilators for enhancing arterial portography].
abstract: In order to improve visualization of the portal vein, an experimental comparative study of enhancing arterial portography with four vasodilators was conducted in 8 dogs and the hemodynamic changes observed after administration of these agents. This study confirms that prostaglandin E1. Vasoactive intestinal peptide and anisodamine can improve the image quality of portal vein in arterial portography, but priscoline is less effective. The mechanism, and technical factors involved and the clinical application of pharmaceutical-arterial portography were discussed. This study also provided the experimental data for a wide choice of vasodilators in enhancing visceral angiography.
