对不宜手术的睥亢患者可以用脾动脉栓塞方法进行“脾切除术”,脾动脉完全阻塞时,死亡率和并发症发生率较高,用明胶海绵(gelatin)作部分脾栓塞已取得一些令人鼓舞的结果,并发症也较少,本文报告用微粒栓子(20-500μ)作部分脾栓塞实验。实验动物为狗。选用了5种栓塞剂,比较它们的栓塞水平、栓塞程度和栓塞的均质性。这5种栓塞剂是: (1)和(2):交键右旋糖酐微粒(Sephadex G25,40～50μ,和Debrisan,50～200μ,Pharmacia) (3)聚苯乙烯微粒(Dowex,20～100μ,Bio-Rad) (4)涂钡聚乙烯醇泡沫微粒(Ivalon,250～500μ,Unippoint)
Sputum arterial embolization can be used for patients with unresectable spasticity for “splenectomy.” When the splenic artery is completely obstructed, the incidence of mortality and complications is high. Some orders have been made with gelatin sponges for partial splenic embolization. Inspired by the results, there are fewer complications. In this paper, microemboli (20-500μ) were used as part of the splenic embolization experiment. Experimental animals are dogs. Five embolic agents were selected and their embolization levels, embolization levels, and embolization homogeneity were compared. The five embolic agents are: (1) and (2): cross-linked dextran microparticles (Sephadex G25, 40-50μ, and Debrisan, 50-200μ, Pharmacia) (3) polystyrene microparticles (Dowex, 20-100μ, Bio-Rad) (4) Coated Polyvinyl Alcohol Foam Particles (Ivalon, 250-500μ, Unippoint)
