Embolization Agents—Which One Should Be Used When? Part 1: Large-Vessel Embolization

Abstract

The first clinical transcatheter embolization procedure was reported in 1972, utilizing autologous clot as the embolic agent. Since then, embolization procedures have become progressively more sophisticated and the number, variety, and complexity of embolic agents has exponentially increased. Hence, one of the most difficult decisions an operator must make before any given embolization procedure is what embolic agent to use.
