| Objective To analyze the influencing factors of deep venous thrombosis (DVT) of lower extremity in patients with convalescent intracerebral hemorrhage(ICH). Methods A retrospective analysis was conducted on 126 patients with ICH admitted to the Department of Rehabilitation Medicine of the First Affiliated Hospital of the University of Science and Technology of China (Anhui Provincial Hospital) from August 2015 to August 2017. The blood routine, blood coagulation, D-dimer, and color doppler ultrasonography of the lower extremity veins of the paralyzed side were completed upon admission. They were divided into DVT group(21 cases) and non-DVT group(105 cases). DVT was diagnosed according to results of color doppler ultrasonography. The clinical data of the two groups of patients were recorded and compared, and multivariate logistic regression analysis on the statistically significant indicators of single factor analysis was carried out to screen the influencing factors of cerebral hemorrhage complicated by DVT. Then meaningful measurement indicators resulted from multivariate analysis were done performance analysis through ROC curve. Results By comparison, differences in clinical data of the two groups including age, ICH treatment, indwelling catheter, foreign body placement, lower limb muscle tension, and D-dimer were statistically significant (P<0.05); multivariate logistic regression analysis showed that lower limbs increased muscle tone[OR(95%CI)=7.564 (1.313~43.571), P=0.024], D-dimer[OR(95%CI)=1.805 (1.151~2.828), P=0.010] was connected with the occurrence of DVT in ICH patients during convalescence; ROC curve analysis showed that when DVT occurred in ICH during convalescence, the area under the curve of D-dimerwas 0.768 (P<0.05), and the corresponding 95% CI was 0.684~0.839. When the optimal cut-off value of D-dimer was 0.68, the diagnostic sensitivity for DVT in convalescent ICH was 95.24%, and the specificity was 48.08%. Conclusion Increased muscle tone of the lower extremities is a protective factor for DVT in patients with ICH during convalescence; D-D is a risk factor for DVT in patients with ICH during convalescence, and has predictive value. |
