IN SPITE of care and experience, we still find the making of aortograms a rather major undertaking. We have reserved it for the urologic diagnostic problem which cannot be solved by other means.
Intravenous angiography, using 50 cc. of 70% sodium acetrizoate (urokon® sodium) injected in the cephalic vein in two seconds by means of a simple home-made lever can help fill the gap between the usual IV urography or retrograde pyelography and the more complicated aortography. We have demonstrated to ourselves that if an intravenous drip of 0.6% procaine hydrochloride is started before injection, the peripheral flush and subsequent headache and nausea are suppressed. Timing of exposures has been the most difficult problem, for a one-second delay may find the column of dye already in the iliac vessels, whereas exposing the film too soon demonstrates only the chambers of the heart. Serial films with a rapid cassette changer are
