title: Computed tomography arteriography to assess greater saphenous vein as a conduit for peripheral bypass.
abstract: BACKGROUND
  To determine whether computed tomography arteriography of the lower extremities (64-slice volume computed tomography (CT)), used in delineating the arterial tree in peripheral vascular disease, is useful in assessing suitability of greater saphenous vein as a vascular conduit for peripheral bypass grafting for limb-threatening lower limb ischaemia. A search of published works in August 2005 showed no similar study has been published.
  
  
  METHODS
  A prospective study of nine consecutive patients who had undergone lower limb CT arteriography and long saphenous vein colour duplex ultrasound (U/S) were studied.
  
  
  RESULTS
  Good concordance between colour duplex U/S and CT arteriography was obtained.
  
  
  CONCLUSIONS
  Computed tomography images of the long saphenous vein as a part of arterial lower limb CT arteriography correlate well with preoperative conduit assessment colour duplex U/S findings of the long saphenous vein.
