Abstract:
Objective To analyze the clinical characteristics and interventional treatment effects of pa-tients with renal arteriovenous fistula in this hospital over the past 10 years.Methods A retrospective analy-sis was conducted on the clinical and imaging data of 40 patients with renal arteriovenous fistula who were treated in this hospital from October 2012 to October 2022.After classifying the fistula type using digital sub-traction angiography(DSA),an individualized embolization plan was developed by a vascular surgery team.Postoperatively,the embolization materials,embolization success rate,clinical success rate,perioperative renal function changes and complications were analyzed.Results A total of 29 cases(72.5%)had acquired renal arteriovenous fistula,while 11 cases(27.5%)had non-acquired renal arteriovenous fistula.Forty-three super-selective transcatheter arterial embolization(TAE)procedures were performed,achieving a technical success rate of 100.0%(40/40)and a clinical success rate of 95.0%(38/40).The mean serum creatinine levels after TAE were(91.39±23.72)mmol/L in the non-acquired group and(105.94±35.51)mmol/L in the acquired group.No statistically significant difference was observed in perioperative serum creatinine changes between the two groups(P=0.095).No severe complications such as renal function deterioration occurred postopera-tively in any patient.Conclusion Gross hematuria serves as the primary clinical manifestation of renal arterio-venous fistula,with abdominal pain being more prevalent in non-acquired renal arteriovenous fistula.The em-bolization approach combining coils with polyvinyl alcohol particles demonstrates favorable safety and efficacy in treating renal arteriovenous fistula.
