选择性动脉栓塞术治疗肾血管平滑肌脂肪瘤的研究进展

Research progress in selective arterial embolization for renal angiomyolipoma

肾血管平滑肌脂肪瘤(RAML)是一种肾脏常见的良性肿瘤,一般多由体检偶然发现,或者当肿瘤破裂出血及肿瘤增大出现相关症状时被发现。选择性动脉栓塞术(SAE)现已成为RAML主要治疗手段。在RAML急性破裂出血时,SAE可作为一线治疗方案。此外,SAE对预防RAML出血及其他严重并发症方面已被证明是安全的、有效的。本文着重对SAE治疗RAML的适应证与禁忌证、栓塞材料的选择、疗效评价、并发症及其防治等方面进行综述。

Clinically,renal angiomyolipoma(RAML)is a commonly-seen benign tumor of the kidney.Usually,it is accidentally found by physical examination or when the clinical relevant symptoms occur due to tumor rupture with bleeding or the tumor size becomes enlarged.Selective arterial embolization(SAE)has become the primary treatment for RAML.SAE can be used as a first-line treatment option in acute rupture with bleeding of RAML.Moreover,SAE is safe and effective in preventing RAML bleeding and other serious complications,which has already been proved.This review focuses on the indications and contraindications for SAE treatment of RAML,selection of embolization materials,evaluation of efficacy,complications and their prevention and treatment,etc.
