Abstract

Although renal angiomyolipoma (AML) is a benign tumor, treatment may be necessary occasionally because it can cause potentially life-threatening retroperitoneal hemorrhage. Transarterial embolization (TAE) is a safe and effective treatment option to prevent the hemorrhagic rupture of AMLs and relieve the symptoms caused by enlarged lesions or active bleeding. However, there is no clear consensus regarding the indications for prophylactic TAE in patients with sporadic renal AMLs. In urgent TAE for bleeding AMLs, there is a likelihood of incomplete embolization when the focus is on stabilizing the clinical symptoms. This pictorial essay discusses the patient selection and technical considerations to achieve optimal therapeutic effects as well as the follow-up findings after TAE.

신장 혈관근지방종은 양성이지만 잠재적으로 생명을 위협할 정도의 후복막강 출혈을 일으킬 수 있으므로 때때로 치료가 필요하다. 경동맥색전술은 혈관근지방종의 출혈성 파열을 예방하고 병변의 비대 또는 출혈로 인한 증상을 완화시킬 수 있는 안전하고 효과적인 치료 방법 중 하나이다. 그러나 산발성 신장 혈관근지방종 환자의 예방적 색전술 시술에 대한 치료기준에 대해서는 명확한 합의가 없다. 게다가 종양 파열에서 시행하는 응급 시술에서는 임상증상의 안정화에 초점을 맞춘 불완전한 색전술의 가능성이 있다. 본 임상화보에서는 사례들을 통해 최적의 치료 효과를 위한 환자 선택 및 색전술의 기술적 및 시술 후 고려 사항을 제시하고자 한다.
