The authors describe a case in which a patient underwent percutaneous cryoablation of a suspected right renal cell carcinoma complicated by bleeding. Urgent angiography revealed a lower renal pole arteriovenous (AV) fistula, correlating with the recent treatment site. This AV fistula was successfully treated with coil and Gelfoam embolization. Three days later, the patient's hemoglobin dropped following dialysis. Computed tomography (CT) imaging revealed an increase in the size of the pararenal hematoma. There were multiple pseudoaneurysms as well as a small AV fistula on repeat angiography. The right main renal artery was coil embolized.
作者描述了一例患者,该患者接受了经皮冷冻消融疑似右肾细胞癌的治疗,但出现了出血并发症。紧急血管造影显示肾下极动静脉瘘,与近期治疗部位相关。该动静脉瘘通过弹簧圈和明胶海绵栓塞成功治疗。三天后,患者透析后血红蛋白下降。计算机断层扫描(CT)成像显示肾周血肿大小增加。再次血管造影显示有多个假性动脉瘤以及一个小的动静脉瘘。右肾主动脉通过弹簧圈进行了栓塞。
