Analysis of the related factors of deep venous thrombosis of healthy side lower extremity in hemiplegia patients after ischemic stroke

ObjectiveTo investigate the incidence rate and risk factors of deep venous thrombosis(DVT) in the healthy side lower extremity in hemiplegia patients after ischemic stroke.

MethodsA total of 147 ischemic stroke patients with hemiplegia were retrospectively analyzed.After admission, the blood routine examination, blood coagulation image, D-dimer and color ultrasound examination in all cases were implemented According to the thrombosis of the healthy side lower extremity, the patients were divided into the healthy side complicated with DVT group(18 cases) and healthy side complicated without DVT group(129 cases).The indexes between two groups were compared.

ResultsThere was no statistical significance in the age, coagulation function, platelet count, incidence rate of pulmonary infection, complicated with hypertension, diabetes and atrial fibrillation rate between two groups(P>0.05).The D-dimer, incidence rate of consciousness disorder and ventilator utilization rate in healthy side complicated with DVT group were higher than those in healthy side complicated without DVT group(P < 0.05 to P < 0.01).

ConclusionsDisturbance of consciousness and use of ventilator are the risk factors of DVT in the healthy side of patients with hemiplegia after ischemic stroke, and lung infection may be a potential risk factor.For patients with these risk factors, the screening of healthy side lower limb thrombosis should be paid more attention.
