[Pharmaco-angiography with angiotensin (author's transl)].

The results of pharmacoangiography using angiotensin were compared with the findings in 101 patients during selective angiography of the kidneys (48 cases), the pancreas and liver (46 cases) and of peripheral soft tissue lesions (7 cases). Angiotensin in a dose of 0.5--l mug (renal artery), 1--5 mug (coeliac artery) and 5--10 mug (peripheral vessels) was found to be a constant and potent vaso-constrictor in 99% of cases. Intraarterial injection of angiotensin improved evaluation in 18 out of 27 cases (66%) with a final diagnosis of a tumor, in 18 out of 22 patients (77%) with cysts and in 16 out of 24 (66%) with an inflammatory process. In three out of 27 cases (11%) an angiographic diagnosis was possible only after using pharmacoangiography. The use of angiotensin represents a valuable possibility of clarifying otherwise uncertain angiographic diagnoses. This is particularly the case where superselective catheterisation is impossible.
