Arterial venography of the dog's leg

Good visualization of the veins of the leg in the dog were obtained simply by increasing the dose to ca. 2 ml per kg tissue weight of contrast agent containing 282-300 mg I/ml. This is equivalent to the dose used in celiac, cerebral and coronary arteriography in man. Moderate increase in flow induced by injection of roentgen contrast agents gave some improvement in the visualization of the veins. Infusions of bradykinin and attempts at reactive hyperemia did not improve the visualization of the veins.
