Objective:
To explore the risk factors of deep vein thrombosis (DVT) in lower extremities.
Methods:
Retrospective data analyses were performed for a total of 1264 DVT patients at our department from January 2010 to December 2012.
Results:
Among them, 984 cases (77.85%) were over 40 years old, no overt cause was found for 642 cases (50.79%), 142 cases (11.23%) had a clear history of trauma before onset (without surgery). Among 316 recurrent postoperative cases, there were the surgical histories of orthopedics (n = 142, 11.23%), gynecology (n = 90, 7.12%), general practice (n = 42, 3.32%), vascular (n = 23, 1.82%), urological (n = 12, 0.94%) and others (n = 7, 0.55%). Ten cases (0.79%) occurred after suffering bedridden chronic diseases. And 20 cases (1.58%) were caused by conditions during pregnancy or postpartum period.had Malignant tumors were found in 25 (1.98%) patients. After long-term uses of hormones, 10 patients (0.79%) of rheumatoid arthritis had a recurrence.Owing to varicose veins, 27 patients (2.14%) recurred. Eight patients (0.63%) had a history of drug abuse, 2 cases (0.16%) suffered depression and 62 cases (4.9%) were recurrent.
Conclusion:
There are many causative factors of DVT so that prevention is of great importance. We should pay more attention to the prevention and treatment of high-risk DVT patients.
