Prevalence of silent deep vein thrombosis detected by Doppler ultrasound in acute stroke patients
ABSTRACT Venous thromboembolism(VTE) it refer to all forms of pathologic thrombosis , occurring on the venous side of the circulation and when it effect thedeep veins it is referred to as deep venous thrombosis (DVT).Many of acute stroke patient develop pulmonary embolism in the absence of symptomatic DVT (silent DVT), the clinical significance of silent DVT in relation to acute stroke is unclear at present. It remains to be seen whether silent DVT is a common complication among patient with acute stroke. Objective: The aim of this study was to help clarify occurrence of DVT based on a screening DUS in patient with acute stroke (ischemic & hemorrhagic) and risk factors for its development. Methods: This cross-sectional study carried out in the period between January and September 2015 in Middle Euphrates neuroscience center at Annajaf city. Ninety tow patients with acute stroke show no clinical evidence of DVT enrolled in the study .36 were female and 56 were male, their ages ranged from 42 to 70 years old. We classified study group into subgroups for purposes of statistical analysis. Results: silent DVT was found in sixpatients with acute stroke (6.52%, n=92). Patients with silent DVT tended to be older as they had mean age of 66.33.While patients without silent DVT had mean age of 58 (P value =0.002),Silent DVT effect age group older than 70 years(p value (0.002).Patient with silent DVTtended to have higher NIHSS score than those without silent DVT (mean 14 vs 7.39, p value=0.003).Silent DVT significantly affectPatients with severe stroke (P value=0.002) and those with sever lower limbs disability (P value =0.006). Conclusion: Our study shows significant presence of silent DVT in patient with acute stroke; hemorrhagic stroke subtype, old age, sever stroke, and sever lower limbs disability were the independent risk factors of its development. Keywards: Silent DVT, stroke type, age, gender, severity of stroke, lower limbs disability.
