近年由于介入性放射学的进展,栓塞治疗已为临床普遍应用。目前已有许多栓塞剂被应用如:自体凝血块,肌肉组织块,明胶海绵(Gelfoam),乙稀泡沫酒精(Ivalon),异丁-2-丙稀酸盐(Isobucty-2-cyanoac-rylate),氰丙烯醋盐(Cyanoacrylate)、不锈钢螺旋丝和亚铁磁性微粒等,但每种都有优点和较大的缺点。Barth 曾在动物身上对自体凝血块,氧化纤维素、和明胶海绵等栓塞剂进行长期的观察,结果没有一种是比较理想的。由于栓塞性不完全,对非栓塞器官的损伤以及某些栓塞剂型的给药方式困难等种种原因迫使人们探索新的栓塞剂。
In recent years, due to the progress of interventional radiology, embolization has been widely used clinically. Numerous embolic agents have been used such as: autologous clot, muscle tissue, Gelfoam, Ivalon, Isobucty-2-cyanoac-rylate Cyanoacrylate, stainless steel spiral wire, and ferromagnetic particles, but each has advantages and major disadvantages. Barth had long observed the effects of autologous blood clots, oxidized cellulose, and gelatin sponges on animals. None of the results were satisfactory. Due to incomplete embolization, damage to non-embolized organs and difficulty in administration of certain embolic agents, various factors are forcing people to explore new embolic agents.
