[Angiographic and computed tomographic findings in intra-arterial cytostasis of colorectal liver metastases].

Between October 1983 and January 1986, sixteen patients with inoperable liver metastases from colorectal carcinomas were treated by single or cyclical intraarterial chemotherapy introduced either through an angiographic catheter or by means of a subcutaneously implanted access point (Port-A-Cath). Before each treatment cycle, the position of the catheter and the state of the vessels was examined by subtraction angiography in order to avoid complications and to confirm that the cytostatic agents were actually perfusing metastases, as shown by angio-CT. The complementary nature of the information obtained by these methods and their superiority over scintigraphy with 99mTc macroaggregated albumin particles is documented and the most frequent complications of regional tumour therapy are described.
