[Visceral and peripheral pharmacoangiography with angiotensin and bradykinin (author's transl)].

In a prospective study of 156 patients a total of 110 pharmacoangiographic examinations using Angiotensin and 46 investigations with Bradykinin were performed. In 21 cases both pharmaca were applied. In 111 patients with pathologic findings (tumors, cysts and inflammatory lesions) diagnostic information compared with conventional angiography, was improved in 80, equal in 26 and reduced in 5 cases. In 21 studied patients using Angiotensin and Bradykinin, the overall diagnostic information was improved. Angiotensin is a suitable pharmacon in demonstration of malignant lesions. Bradykinin improves the demonstration of vessels affected by local inflammation and allows better visualization of the veins. The application of both pharmaca may help in certain cases to differentiate between inflammatory and malignant lesions.
