A study on selective renal epinephrine pharmacoangiography

Han, M C

Abstract

Selective renal arteriography has been recognized as highly diagnostic and widely popularized method fordetection and evauation of various renal diseases, especially of malignant tumors Since Abrams had advocatedepinephrine pharmacoangiography, a few reports on this subjecti has appeared in the literature. At Department of Radiology, Seoul National University Hospital, a total 22 patients whom renal disease was suspected, were studiedwith selective renal arteriography, during from August 1971 to March 1973. Aortogram, selective renal arteriogramand epinephrine pharmacoangiogram were comprehensively analized. In all of 7 cases which are angiographicallynormal, proper contraction of renal artery to epinephrine is observed. In 3 cases of simple cyst and 3 cases ofother benign process, again proper response to epinephrine is noted. In all 8 cases of proven renal cell carcinomaand a case of transitional carcinoma, there is abnormal response to epinephrine, i,e. lack of contraction,however. It appears to be clear that epinephrine pharmacoangiography is safe and excellent modality for early andaccurate diagnosis of malignant renal tumors.
