ABSTRACT

Objective: To study the efficacy,safety and relative characteristics of formulated Chinese medicinal herbs as a vascular embolizing agent. Methods: We prepared a mixture as a vascular embolizing agent from several Chinese medicinal herbs,they served as anticarcinogen and/or coagulant according to the Chinese Pharmacopeia.We studied the characteristics of the mixture through embolizing the hepatic artery in eight pigs with it. Results: The mixture was prepared as a suspension.It was easily injected through catheters and showed good histocompatibility and hemo-compatibility without pyrogenetic response and toxicity.The mixture mainly embolized peripheral arteries,maintaining occlusion for 5 weeks and without formation of collateral circulation.We found injuries of normal hepatic tissues as slight hepatocyte hydrops and focal endochyloma necrosis through optical and electronic microscope. Conclusion: This suspended mixture of Chinese medicinal herbs is safe and effective as a potential peripheral embolizing agent.
