New materials in embolizations

Percutaneous, catheter-directed embolotherapy is an established interventional technique for the management of many vascular disorders. For more than three decades, typical embolization devices included macro and microcoils, polyvinyl alcohol microparticles, glue and certain liquids such as absolute alcohol. In the past decade, however, several new embolic devices and refinements of existing embolic devices have arrived on the market and a number of clinical studies have demonstrated their added value. In this review article, these new embolic devices and their typical indications will be discussed, as well as the results of studies involving the embolic devices.status: publishe
