Abstract:

BACKGROUND: Deep vein thrombosis occurred during waiting period before operation affects the prognosis of calcaneal fractures. Therefore, it has important clinical significance for its accurate diagnosis. The staging of thrombosis during waiting period before operation for calcaneal fractures is rarely reported.

OBJECTIVE: To detect the incidence and risk factors of deep vein thrombosis in patients with calcaneal fracture by ultrasound elastography imaging after staging diagnosis of thrombosis.
METHODS: All objects were included in the study from patients with calcaneal fractures waiting for surgery in the Qinghai University Affiliated Hospital between 2008 and 2015. Patients received preoperative duplex ultrasonography. Those with thrombosis received ultrasound elastography. The incidence of thrombosis was calculated. According to medical records, age, sex, body mass index and history of smoking were collected. The correlation between thrombosis and above factors was analyzed by multiple Logistic regression analysis.
RESULTS AND CONCLUSION: (1) One hundred and forty-nine patients were finally included. Of these, 22 (14.8%) were found to affect deep vein thrombosis in the lower limb. The incidence of acute thrombosis was 9.4%. (2) Multiple Logistic regression analysis suggested that age (P=0.009, OR=1.063, 95% confidence interval (CI) 1.010–1.117), body mass index (P=0.019, OR=1.302, 95% CI 1.124–1.430), history of smoking (P=0.017, OR=5.124, 95% CI 1.347-18.359), and operation waiting time (P=0.000, OR=5.190, 95% CI 1.396–19.266) were risk factors of acute lower extremity deep venous thrombosis. (3) These results suggest that the incidences of preoperative deep vein thrombosis and acute deep vein thrombosis are very high. The risk assessment of acute deep vein thrombosis should be taken according to the patient’s age, smoking history, body mass index, as well as the time waiting for surgery. The corresponding diagnosis and treatment program should be given to patients with thrombosis.
