title: Change in the lower limb deep venous flow in peripheral atherosclerotic arterial disease.
abstract: OBJECTIVE
  This prospective study was undertaken to determine how peripheral atherosclerotic disease influences the flow in the deep veins of the leg.
  
  
  METHODS
  Thirty one subjects with peripheral atherosclerotic disease and 23 age matched control subjects were studied. The popliteal vein flow velocity was measured at rest and during reactive hyperemia by means of color duplex ultrasound scanning. Patient age, ankle-brachial index (ABI) and the presence of risk factors for venous thrombosis were also recorded.
  
  
  RESULTS
  There was a negative correlation between the ankle-brachial index and venous flow velocity among subjects with peripheral arterial disease (p=0.001). There was a negative correlation between dyslipidemia and resting venous flow velocity (p=0.049). During reactive hyperemia, venous flow velocity increased less in subjects with peripheral arterial disease than it did in control subjects (p=0.007). The subjects with dyslipidemia showed no changes in venous flow velocity in reactive hyperemia measurements (p=0.908).
  
  
  CONCLUSIONS
  Increasing the venous flow velocity in peripheral arterial disease, may confer some protection against the deep venous thrombosis.
