Risk factors for deep vein thrombosis after cerebral hemorrhage / 中华物理医学与康复杂志

ABSTRACT

Objective To explore the risk factors for deep vein thrombosis (DVT) of the lower extremity among patients hospitalized after a cerebral hemorrhage. Methods A total of 230 patients with cerebral hemorrhage admitted between August 2015 to August 2017 were retrospectively analyzed. At admission, each was were given a coagulogram, D-dimer and color Doppler ultrasound of the lower extremity. The patients were divided into a DVT group (31 cases) and a non-DVT group (199 cases) according to the color Doppler ultrasound results. The following clinical information was recorded: sex, age, disease course, paralysis side, consciousness, tracheotomy, complications (pulmonary infection, urinary tract infections and pressure sores), foreign matter implanting, history of venous catheterization, heart rate over 100 beats/ min or not, rehabilitation intervention after the onset, muscle tension in the lower extremity, activity and swelling on the paralysis side, and the serum levels of D-dimer and fibrinogen. Univariate and multivariate logistic regression was applied in search of useful risk factors. Results The univariate analysis showed that age, gender, disease course, tracheotomy, urinary tract infections, pressure sores, foreign matter implanting, and swelling and muscle tension in the lower extremity were all associated with the occurrence of DVT among these cerebral hemorrhage patients. According to the results of the multivariate logistic regression analysis, swelling and muscle tension in the lower extremity were related with the occurrence of DVT for those patients. Conclusion Swelling and muscle tension in a lower extremity are independent risk factors for the occurrence of DVT after a cerebral hemorrhage.__
