title: Role of embolic protection devices in ostial saphenous vein graft lesions.
abstract: BACKGROUND
  Although embolic protection devices (EPDs) have been shown to be beneficial in saphenous vein graft (SVG) lesions, their role in the subgroup of ostial SVG lesions has received limited study.
  
  
  METHODS
  The coronary angiograms and procedural outcomes of 109 patients undergoing stenting of 113 ostial SVG lesions were retrospectively reviewed to determine the frequency of EPD use and the periprocedural outcomes.
  
  
  RESULTS
  Ninety-eight (87%) of the 113 lesions were suitable for EPD use, that was used in 70 lesions (71%). A Filterwire (Boston Scientific) or a SPIDER (ev3) filter were used in 54 (77%) and 16 (23%) of lesions, respectively. Difficulty retrieving the filter post stenting was encountered in eight lesions (11%) and led to stent thrombosis causing cardiac arrest in one patient (1%). Angiographic success was achieved in 111 (98%) of 113 lesions.
  
  
  CONCLUSIONS
  EPDs can be utilized in the majority of ostial SVG lesions, but in 11% of cases filter retrieval can be challenging and may rarely (in approximately 1%) lead to a significant complication.
