We report a case of computed tomography-guided percutaneous radiofrequency ablation of a bleeding renal angiomyolipoma. Radiofrequency ablation was performed as an alternative to partial nephrectomy and super-selective renal artery embolization for ruptured renal angiomyolipoma with slow persistent bleeding in a patient with elevated serum creatinine levels and other comorbidities. Computed tomography-guided radiofrequency ablation successfully stopped the active hemorrhage and did not affect long-term renal function during the 3-year follow period. No complications were associated with the procedure. Radiofrequency ablation of a bleeding renal angiomyolipoma may be considered a more invasive surrogate procedure in an urgent setting; however, further studies are necessary to evaluate the long-term benefits of this approach and its overall impact on renal function compared to traditional methods.
我们报告一例计算机断层扫描引导下经皮射频消融治疗出血性肾血管平滑肌脂肪瘤的病例。对于一名血清肌酐水平升高且伴有其他合并症、肾血管平滑肌脂肪瘤破裂并伴有缓慢持续性出血的患者，射频消融作为部分肾切除术和超选择性肾动脉栓塞术的替代方法进行。计算机断层扫描引导下的射频消融成功止住了活动性出血，并且在3年的随访期内未影响长期肾功能。该手术未出现并发症。在紧急情况下，出血性肾血管平滑肌脂肪瘤的射频消融可被视为一种侵入性更强的替代手术；然而，与传统方法相比，有必要进行进一步研究以评估这种方法的长期益处及其对肾功能的总体影响。
