Abstract: | A 56‐year‐old Asian woman was admitted to hospital for the consideration of hemodialysis (HD). A right femoral dialysis catheter was inserted for HD. Three months after removal of catheter, she was admitted because of right inguinal swelling. A thrill and bruit were felt and heard at the inguinal area. Color Doppler detected a fistula between right superficial femoral artery and right common femoral vein and subsequently confirmed by contrast enhanced computed tomography scan and 3‐dimensional reconstruction with computed tomography. At surgery, a 4‐mm–diameter fistula was found between the right superficial femoral artery and right common femoral vein. A primary closure of both defects in the artery and vein was then carried out. A follow‐up digital vascular study 3 months after surgical repair was normal. In conclusion, nephrologist should have a heightened awareness to the potential of this complication and should at least document a normal exam following the removal of femoral catheters. |
