摘要
目的：评价静脉尿路造影（ＩＶＵ）、超声（ＵＳ）、ＣＴ和肾动脉造影在先天性肾动－静脉畸形（ＲＡＶＭ）诊断中的作用，评价经导管栓塞（ＴＣＥ）在本病治疗中的作用，并复习文献。材料与方法：２例持续肉眼血尿的男性患者，均有ＩＶＵ、ＵＳ、ＣＴ和肾动脉造影，并对其影像表现进行分析和比较，动－静脉畸形用明胶海绵颗粒、钢圈、鱼肝油酸钠经导管栓塞。结果：ＩＶＵ、ＵＳ和ＣＴ几乎不能发现ＲＡＶＭ的阳性表现，肾动脉造影可以显示病灶的位置、形态和确切大小。用超选择栓塞治疗可以便动－静脉畸形的供血动脉闭塞，且在随访期间没有复发征象。结论：目前认为：肾动脉造影仍是诊断ＲＡＶＭ的最可靠方法，选择栓塞供血动脉是治疗ＲＡＶＭ有效、安全的方法。
Purpose:To evalute the roles of intravenous urogram(IVU);Ultrasound(US),CT,renal arteriography in the diagnosis of congenital renal arteriovenous malformation(RAVM) and transcatheter embolization(TC) in its management combined with review of the literture.Materials and Methods:Two men had continual gross hemeture.IVU,US,CT and renal arte riography were pertormed respectivily.The appearances of the images were analized and com pared.The RAVMs were embolized with Gelform particles,metal coils and sodium morrhuate.Results:Few positive appearances of the RAVMs could not be found by IVU,US,CT.The lo cation,shape and exact size of the RAVMs were cemontrated by renal arteriography.The feeding arteries of the RAVM s were eliminated by superselective embolized.There were no evidence of recurrence in both cases during the following up Conclusion:At present renal ar teriography is still the most、reliable method in the diagnosis of RAVM,the feeding arterial embolization is an effective and safe approach to the cure of RAVMs.
