経腰的連続大動脈撮影法

Abstract

We have been taken translumbar serial aortograp h y in 37 cases and we report its into details. We reviewed about many sort of serial roentgenographic apparatus, but we used usually "rapid cassette changing devices-Shimadzu" as a most simply controlled, distinctly shadowing one. The pic t u re of the abdominal aorta, renal arteries, intrarenal arterioles and nephrogram was obtained time by time with serial taking, therefore this method follewed many significant diagnostic value, such as differentiation of renal tumor from cyst, accurate diagnosis of Goldblatt kidney, thromboarteritis obliterans and so on. Arteriogram, that is the figure of renal arteries and its intraren a l branches, was taken from 1 to 3 second (average 1.8 second), and nephrogram was 2-6 second (average 4.0 second) after initiation of translumbar injection of dye. We obtained aortogram and nephrogram satisfact o rily by 5 serial films with 1.0 second interval for clinical use. When the most fine arteriogram is required, 10 serial films with 0.5 second interval was available.
