title: Unreliability of depopulated bovine ureteric xenograft for infra inguinal bypass surgery: mid-term results from two vascular centres.
abstract: BACKGROUND
  We report a two centre experience with a depopulated ureteric xenograft (SGVG 100), CryoLife Inc., GA, USA) for femoropopliteal revascularization in 12 patients with chronic critical limb ischemia.
  
  
  METHODS
  Between 7 days and 18 months after implantation, 10 of 12 patients (1 lost to follow-up) had the graft explanted due to aneurysmal enlargement. At 5 years, only one graft was still patent and showed moderate signs of enlargement.
  
  
  CONCLUSIONS
  The SGVG 100 is not a safe conduit for femoropopliteal bypass surgery.
