A 50-year-old man with von Hippel-Lindau syndrome who had undergone repeated tumor enucleation and transcatheter arterial embolization for multiple renal cell carcinomas (RCC) was referred to our hospital for percutaneous cryoablation (PCA) of an RCC of 42 mm in the midpole region of the right kidney. Transcatheter arterial embolization was planned prior to devascularize the RCC and selective angiography revealed parasitic arterial supply to the tumor by the ileocecal artery. Parasitic arterial supply to RCCs, particularly in patients with history of nephron-sparing treatment, can originate even from an intraperitoneal source and may lead to unexpected embolization.
一名患有冯·希佩尔-林道综合征的50岁男性，因多发性肾细胞癌（RCC）接受了多次肿瘤摘除术和经导管动脉栓塞术，现因右肾中极区域一个42mm的肾细胞癌被转诊至我院进行经皮冷冻消融（PCA）。计划在经导管动脉栓塞术使肾细胞癌去血管化之前进行选择性血管造影，结果显示肿瘤有来自回盲动脉的寄生动脉供血。肾细胞癌的寄生动脉供血，尤其是有保留肾单位治疗史的患者，甚至可能起源于腹腔内，可能导致意外栓塞。
