Chimio-embolisation des métastases osseuses symptomatiques : aspects techniques et intérêt thérapeutique

Chemoembolization of bone metastases is defined by the intraarterial perfusion of a chemotherapy agent followed by microparticles embolization to improve tissue impregnation. This technique increases the local concentration of the chemotherapy agent. Tumor response (stable or reduced tumor size) is achieved in 30-80% of cases with symptomatic relief in over 80% of cases. The indications, technical considerations, and effectiveness of this procedure will be reviewed.
