Abstract

Intraarterial digital subtraction angiography(IADSA) was developed to subjugate the disadvantages of intravenous digital subtraction angiography(IVDSA). Recently, its utility has been increased in renal diseases. For investigation of clinical significance of IADSA in renal diseases, we analysed with 22 patients that renal IADSA had been performed in during the period from May, l984 to January, l986. The following results were obtained; l. Indications of the renal IADSA were renal bleeding, flank mass, hypertension and abnormality IVP or RGP only. 2. Diagnostic accuracy of the renal IADSA in renal diseases was 82.4%. 3. Renal toxicity and pain could be reduced due to decreased dose and dilution of contrast material. 4. Utilization of embolotherapy was increased because of better imaging of the renal vascularity and shortened examination-time of renal IADSA. 5. Renal IADSA can be substituted for conventional renal angiography and renal IVDSA in almost all renal diseases.
