[Clinical Application and Clinical Evaluation Concerns of Embolization Microspheres].

Abstract

Embolization microspheres can be used for the embolization of hypervascular malignant tumors of parenchymal organs. They can also be used as an adjuvant therapy for surgery to reduce perioperative bleeding through preoperative intravascular embolization of tumors. This study summarizes the clinical guidelines and consensus on embolization microspheres and introduces the guidance document for embolization microspheres issued by the Food and Drug Administration (FDA). Additionally, this study presents the authors' thoughts on clinical review of embolization microspheres, aiming to provide insights for the clinical evaluation and technical review of such products.
