Abstract:
Objective To evaluate the efficacy and safety of super-selective renal artery embolization in treatment of iatrogenie renal pseudoaneurysm and arteriovenous fistula.Methods Twenty-nine patients with iatrogenic renal pseudoaneurysm and arteriovenous fistula underwent renal angiography after ineffective conservative treatment.After identifying the location and characteristic of lesions by DSA,super-selective renal artery embolization was performed.Symptoms and signs,renal function changes before and after embolization and complications were recorded to evaluate the therapeutic effect.Results The technical success rate of super-selective renal artery embolization was 100％ (29/29),and clinical success rate was 96.55 ％ (28/29).The serum creatinine level before and after embolotherapy was (93.26 ± 28.79) mmol/L and (91.51 ± 27.68) mmol/L respectively,and there were no significant differences (t=1.28,P=0.22).No serious complications such as nephrapostasis or renal failure occurred in the study.Conclusion Super-selective renal artery embolization has technically and clinically high success rate with limited effect on renal function.It is a safe and effective therapy method in patients with iatrogenic renal pseudoaneurysm and arteriovenous fistula.
