In numerous tumors, metastasis can be limited to the liver. In non-resectable patients, regional treatment modalities, especially arterial cytostatic infusion, are favored in contrast to systemic chemotherapy, whereas intraportal or intraperitoneal application is not successful. Improved results with high response rates have been reported after development of intra-arterial (i.a.) long-term regimens with FUdR in patients with colorectal liver metastases using implantable pumps and ports. However, a survival benefit could only be demonstrated in comparison with a control group only treated symptomatically. Because of several reports on major local toxicity of i.a. FUdR treatment (i.e. chemical hepatitis and biliary sclerosis) several other effective i.a. 5-FU regimens have been developed. A randomized study has demonstrated superiority of i.a. 5-FU versus i.a. FUdR. In comparison with systemic treatment, superiority has only been demonstrated in patients with an intrahepatic tumor burden of < 25%. Publications about regional treatment of patients with breast, gastric cancer or carcinoid liver metastases are rare. Despite the high response rates reported, the benefit of arterial chemotherapy remains questionable. Overall, local long-term chemotherapy cannot be recommended outside of studies as a primary treatment. However, extensive experience and new drugs support the idea of conducting further regional studies.

The indirect arthrography improves the signal parameters of the structures. The detection of labrum lesions is improved, but still remains difficult.
