Comparative Study of Deep Vein Thrombosis Recanalization Using Doppler Ultrasound in Different Post-Treatment Intervals in Traumatic Patients


Deep vein thrombosis (DVT) is a prevalent vascular disease characterized by pelvic and limb deep vein thrombophlebitis, and it has a high incidence in traumatic patients. Contrary to older studies, recent research has reported that recanalization in DVT is not a slow process. The present study aimed at the comparative examination of DVT recanalization with Doppler ultrasound in different intervals following treatment with heparin or enoxaparin. This prospective study was conducted on all traumatic patients hospitalized in Imam Reza Hospital of Kermanshah, Iran, with the clinical and sonographic diagnosis of DVT in limb veins. Doppler ultrasound was performed two weeks, one month, and three months following treatment in order to examine recanalization. Data were analyzed using statistical tests in SPSS16 at the significance level of <0.05. Based on Doppler ultrasound, a significant difference was found between the degree of recanalization in patients aged <45 years and those aged >45 years, between male and female patients, and between different DVT locations (P<0.05). After three months of treatment with heparin and enoxaparin, the degree of recanalization was increased in DVT. Moreover, it was found that Doppler ultrasound is a useful tool for the diagnosis of recanalization in patients with DVT.
