title: [DSA for the imaging of tumor-caused vascular changes and complications during local chemotherapy of the liver via the portal system].
abstract: In 18 patients with primary or secondary liver tumours, 38 digital subtraction angiographies (DSA) of totally implanted catheter systems for liver perfusion were performed during a period of 8 months. The systems had been used for an average of 6.9 months. In 22 out of 38 examinations secondary reactions of liver arteries were observed, in 7 the therapeutic regimen was changed after DSA. Patients with an extensive tumour involvement of the liver showed mural thromboses or obstructions of liver arteries relatively more often (4 of 7) than patients with smaller size tumours (2 of 11). In 7 cases the therapeutic regimen was changed after DSA. DSA of implanted liver catheters is a valuable, well tolerated, easily and rapidly performed method.
