title: Deep vein thrombosis following ischemic stroke among Asians.
abstract: BACKGROUND
  Deep vein thrombosis (DVT) is perceived as uncommon among Asian stroke patients. However, there is a paucity of published data, and thus, we studied the frequency, characteristics and prognosis of DVT following ischemic stroke in Asian patients with lower limb paresis.
  
  
  METHODS
  Doppler ultrasound scans of the lower limbs were performed at days 7-10 and 25-30 after stroke onset. The functional status of patients was assessed at 6 months using the modified Rankin scale.
  
  
  RESULTS
  DVT was detected in 30% of patients at days 7-10 and in 45% of patients at days 25-30. Most thromboses were distal. There were significant associations of age and degree of weakness with the presence of DVT at days 25-30, but not at days 7-10. DVT in the first month after stroke was associated with poorer outcome at 6 months.
  
  
  CONCLUSIONS
  DVT following ischemic stroke among Asians is common and associated with poor functional outcome.
