Abstract
The aim of preoperative embolization is to facilitate surgical removal by reducing tumor volume and vascularity, thereby decreasing blood loss during surgery. In a search for a better embolic material, compared to heterogeneous commercial products, we describe here in detail the preparation of poly (D,L) lactide microspheres by an emulsion-solvent evaporation process. The size distribution of the microparticles and their aggregation state-critical parameters in view of such application-have been investigated. Their effectiveness, as an embolic material, has been evaluated by some preliminary experiments undertaken on humans. The results were assessed on clinical and histological grounds.
