Abstract
Objective:To identify the risk factors of deep vein thrombosis (DVT) of lower limb in patients undergoing lumbar fusion surgeries, to provide a better understanding of DVT and take prophylactic measures.Methods:This study was carried out in our hospital between January 2016 and February 2020, patients undergoing lumbar fusion surgeries were included and divided into DVT group and non-DVT group, and the medical data including basic demographics, clinical characteristics, operative data, and routine biochemical parameters were collected and analyzed.Results:In the current study, 390 cases were included, 48 cases were enrolled in DVT group and 342 in non-DVT group. The incidence of DVT was 12.3%. There were significant differences in age, hyperlipemia, hypertension, occupation type, D-dimer level, hospital stay, and postoperative exercises (p<0.05), but no significant differences in gender, smoking status, drinking status, coronary heart disease, diabetes mellitus, fused segments, and operation time (p>0.05) between the two groups. In multivariate analysis, age>50 years, hypertension, D-dimer>500ug/L were independent risk factors, while postoperative exercises were protective factor for DVT.Conclusion:Those patients undergoing lumbar fusion surgeries should take more prophylactic measures including postoperative exercises if they were elderly, or hypertensive, or have high D-dimer level, in order to decrease the incidence of DVT.
Highlights
Lower limb deep vein thrombosis (DVT), one of the common complications in patients suffering from surgeries, can lead to high mortality once pulmonary embolism occurs.[1]
48 cases were diagnosed with DVT and enrolled in DVT group, in which no pulmonary embolism occurred, and the remaining 342 cases were enrolled in non-DVT group
In the DVT group, DVT was found in left lower extremity, right lower extremity, and both lower
Summary
Lower limb deep vein thrombosis (DVT), one of the common complications in patients suffering from surgeries, can lead to high mortality once pulmonary embolism occurs.[1] It is estimated that a large number of patients, approximately 200 000 people, die from pulmonary embolism in the world each year.[2] how to prevent the occurrence of DVT in patients after surgeries is highly valued in the field of medicine. Lumbar fusion surgery is widely used in the treatment of lumbar degenerative disc disease with a satisfying effectiveness. The rate of DVT is high in these patients. In a study of 995 patients who suffered from lumbar fusion surgeries, Yang reported that 223 patients were
