Retrospective analysis of clinical characteristics of hospitalized patients with deep venous thrombosis of lower extremity in regional central hospital

Abstract

Objective To investigate the characteristics of the disease and the trend of diagnosis and treatment of patients with deep venous thrombosis (DVT) admitted to the First Affiliated Hospital,Xi'an Jiaotong University from October 2015 to October 2018. Methods The clinical data such as age, gender, clinical manifestations, location of thrombosis, and proportion conforming to DVT risk factors and treatment trends of patients with DVT were analyzed retrospectively. Results There was no difference in the prevalence between men and women in 1 032 patients with DVT. Patients in the acute phase were more common, accounting for 65.02% (671/1 032) . DVT was easy to accumulate left lower limbs, and the hole limb type was the most common type of thrombus, accounting for 76.48% (868/1 135) . The common risk factors for DVT were age ≥ 40 years (91.28%) , history of cardiovascular and cerebrovascular disease (36.72%) , history of trauma/surgery (27.33%) , history of sedentariness (22.38%) , history of smoking in male (43.51%) , etc.. The most common types of surgery were orthopedic surgery (47.73%) , gynecologic surgery (14.77%) , general surgery (13.07%) , vascular surgery (7.95%) , urology surgery (7.39%) and neurosurgery (3.98%) . In the acute phase, 90.57% of the D-dimer mers were ≥1, while in the chronic phase, only 63.19% of the D-dimer mers were ≥1. In terms of treatment, the use of preventive recyclable filters has increased year by year. Among the patients in the acute phase, 22.95% (154/671) received catheter thrombolysis. In the long-term treatment plan, rivaroxaban gradually replaced the traditional warfarin and became a conventional anticoagulant. Conclusion The DVT of the lower extremities is currently high in our region, the risk factors are complex, and needs to be taken seriously. The standardization of diagnosis and treatment of DVT still needs to be strengthened. Key words: Deep venous thrombosis; Risk factors; Treatment trends; Retrospective studies
