What is the optimal embolization technique in GAE? In this BackTable Brief, Dr. Osman Ahmed and Dr. Sid Padia, MD discuss the embolization of abnormal vessels, debating between targeting any abnormal vessel versus only the painful side. They reference studies and papers, including the Landers 2023 paper, to explore best practices. 

They consider the use of temporary resorbable embolics compared to permanent embolics, examining safety profiles, efficacy, and potential complications. The conversation then shifts towards the size of embolic particles and endpoints for different embolization materials. They discuss specific techniques and their impacts, highlighting the reproducibility of certain methods and preparing for the future of resorbable embolics in various medical applications.
