[Intra-arterial angio-CT as a perfusion control before intra-arterial chemotherapy in bronchial, breast and liver tumors].

Intra-arterial angio-CT is used increasingly in the diagnosis of liver metastases since the sensitivity of this method is greater than that of IV-contrast CTs. We carried out this procedure in eight patients with inoperable carcinomas of the bronchus, eight patients with carcinoma of the breast, one patient with an hepatocellular carcinoma and one patient with carcinoma metastases, before starting intra-arterial chemotherapy or tumour embolisation. The procedure permitted optimal placing of the catheter to ensure complete perfusion of the tumour. Perfusion of normal tissue can be reduced to a minimum. Failure of contrast filling on the angio-CT indicates the presence of a second vessel supplying the tumour.
