Diagnostic and treatable experience of the iatrogenic femoral arteriovenous fistulas:retrospective analysis of 6 cases

Objective To evaluate the diagnostic and treatable experience of the iatrogenic femoral arteriovenous fistulas.Methods We analyzed 6 patients with iatrogenic femoral arteriovenous fistulas in the methods of diagnosis and treatment during January 2004 to August 2009 retrospectively.Results 6 patients were all detected post catheterization,diagnosed with color doppler ultrasonography as arteriovenous fistulas,3 in common femoral artery,2 in superficial femoral artery,1 in profound femoral artery.The size of the fistula was between 2～4 mm.All the patients were treated with open surgery of fistula repairment.Conclusion Color doppler ultrasonography could be the first choice in the diagnosis of iatrogenic femoral arteriovenous fistulas,and promptly open surgery is still the economical and maneuverability treatment in low morbidities.
