title: Treatment of internal mammary artery malperfusion syndrome by additional venous graft: early postoperative angiographic results.
abstract: BACKGROUND
  Internal mammary artery malperfusion syndrome is caused by an acute imbalance between myocardial demand and nutritional support through the mammary artery.
  
  
  METHODS
  We performed early angiography in 11 consecutive patients in whom the perioperative course suggested mammary artery malperfusion. All patients received an additional saphenous vein graft distally to the mammary artery anastomosis.
  
  
  RESULTS
  Postoperative angiography revealed patent mammary artery and vein graft in 10 patients (three with a markedly reduced caliber of the arterial graft).
  
  
  CONCLUSIONS
  Additional vein graft is the treatment of choice in mammary artery malperfusion syndrome; it does not lead to occlusion of the internal mammary artery.
