【摘要】 目的 介绍一种快速建立的继发性脾功能亢进(脾亢)的猪动物模型,并在此模型基础上进行射频消融治疗(RFA)研究。方法 在B型超声或CT导向下经皮穿刺猪脾静脉主干并栓塞引起淤血性脾肿大,再进行RFA治疗,观察动物外周血细胞变化,了解脾脏影像学变化以及组织病理学改变。结果 脾静脉栓塞后 1周外周血红细胞、血小板即下降,第 3 周以后二者下降明显(P < 0.05),红细胞和血小板减少,脾肿大可持续 6 周以上。术后第 2 周起,脾脏组织学改变符合脾淤血改变。射频热能引起脾脏局部凝固坏死,脾内血管闭塞、广泛微血栓导致血栓性梗死形成。结论 经皮脾静脉栓塞建立继发性脾亢方法简单、确切,可以作为脾亢外科或介入治疗的较理想模型,RFA治疗是一种有效的干预措施。
