Liquid Embolics: A Guide to Currently Available and Pipeline Products

Over the last decade, several publications have reported the safety and efficacy of liquid embolics in a wide range of clinical indications. The expansion of clinical scenarios in which liquid embolics are utilized has been in part driven by some of the advantages these materials hold over other embolic agents. For instance, liquid embolics do not rely on the patient's ability to form clot and can be delivered more distally then coils at times. While several liquid embolics are commercially available, and in some cases have been for decades, there are limitations to these materials as well. The potential benefits of liquid embolics combined with the limitations of available materials have led to the ongoing development of several new agents. This review aims to familiarize the reader with both available liquid embolics and those that are relatively new or in development.
