title: [Segmental variations of great saphenous vein diameters in a coronary triple vessel disease population].
abstract: BACKGROUND
  Great saphenous vein is one of the most used grafts in cardiovascular surgery. There is little amount of data in the medical literature describing dimensions of this vein. This series describes dimensions of the great saphenous vein in a coronary population and their variations.
  
  
  METHODS
  Retrospective series of patients admitted to the cardiovascular surgery department of Hotel-Dieu de France Hospital - Beirut, between January 2003 and June 2006 for elective coronary artery bypass grafting and having a preoperative Doppler ultrasound of the saphenous veins according to a standardized protocol. Great saphenous vein dimensions were analyzed with regard to patients' characteristics using multivariable analysis of variance.
  
  
  RESULTS
  Four hundred and two subjects were included with a mean age 64.4+/-9.3 years and a mean body mass index 27.9+/-4.5 kg/m(2). Women presented 22.6% of the series. Great saphenous vein dimensions' variations according to gender were significant (Multivariate Pillay trace=0.001) below the knee. Dimensions' variations were also significant as function of body mass index (P=0.001) and body surface (P=0.001). Age and cardiovascular risk factors did not influence GSV diameters.
  
  
  CONCLUSIONS
  This series allowed constructing reference tables of the great saphenous vein segmental diameters in patients admitted for coronary artery surgery. Female sex is associated with lower segmental diameters below the knee and body mass index and body surface are linearly associated with segmental diameters at all levels.
