Objective:To investigate the deep venous thrombosis in ICU

including its morbidity rate

causes

monitoring

therapy and prognosis.Methods:A clinical retrospective analysis was carried out to investigate 32 patients with deep venous thrombosis in ICU.Re- sults:The morbidity of deep venous thrombosis in ICU was 4.7 percent(32/681)

and the top three causes were severe acute pancreatitis (46.9 percent

15/32)

multiple injurie(s28.1percent

9/32)

hypertensive cerebral hemorrhage(12.5 percent

4/32)in the investigated 32 cases.Factors significantly inducing deep venous thrombosis were deep venous catheter or bedridden or blood hypercoagulability.30 patients

accounting for 93.8 percen(t30/32)were cured after the treatment of lifting sickness limbs

and anticoagulation and thrombolysis 7 to 14 days.Only one patient was complicated by pulmonary embolism

but no one died.Conclusion:Deep venous thrombosis occurred for multiple causes.The serious patients in ICU were highly dangerous for it.We should pay attention to the high-risk people to avoid vascular complications.The d-dimmer detection

platelet count and deep venous color Doppler inspection were the effective ways to monitor it.The key to cure deep venous thrombosis was early finding and early treatment with anticoagulation and thrombolysis.
