目的:探讨肾动静脉瘘(RAVF)的诊断和治疗方法,提高RAVF的诊治水平。方法:回顾性分析28例RAVF患者的临床资料。28例患者均行肾动脉造影确诊,26例患者行选择性肾动脉栓塞,1例失败改行开放手术;3例开放手术中,2例巨大、高流量RAVF行患肾切除,1例行瘘供血动脉结扎。结果:术后28例患者均治愈;随访4~40个月,1例因血尿再发行二次栓塞,其他患者无血尿再发;所有患者肾功能正常。结论:肾动脉造影和动脉栓塞治疗是RAVF的首选诊治方法,巨大、高流量RAVF应选择外科手术治疗。
Objective: To investigate the diagnosis and treatment of renal arteriovenous fistula (RAVF) and to improve the diagnosis and treatment of RAVF. Methods: The clinical data of 28 RAVF patients were retrospectively analyzed. Twenty-eight patients were diagnosed with renal artery angiography. Twenty-six patients underwent selective renal artery embolization and one patient failed to switch to open surgery. In 3 patients undergoing open surgery, 2 patients with large and high-flow RAVF were treated with nephrectomy and 1 patient received fistula blood supply Artery ligation. Results: All the 28 patients were cured after the operation. The patients were followed up for 4 to 40 months. One patient was re-embolized by hematuria and the other patients had no recurrence of hematuria. All patients had normal renal function. Conclusion: Renal artery angiography and arterial embolization are the first choice for diagnosis and treatment of RAVF. Surgical treatment should be selected for the huge and high-flow RAVF.
