The objective of this retrospective study was to investigate the prevalence of asymptomatic deep vein thrombosis (DVT) and the risk of DVT in patients admitted to hospital for total knee arthroplasty (TKA).
From September of 2003 to December of 2013, 322 patients admitted for TKA were eligible for this retrospective study. A diagnosis of DVT was confirmed by Doppler ultrasonography. The prevalence of silent DVT in the lower limbs in patients before TKA was assessed. The risk factors for preoperative DVT were investigated, as well as the correlation of DVT in the patient's background and medical history.
Preoperative DVT was diagnosed in 56 patients (17.4%) including 3 patients with proximal DVT. Significantly elevated risks of DVT were found in patients undergoing revision TKA (p < 0.01), patients with rheumatoid arthritis (RA) (p < 0.005), patients with connective tissue diseases (CTDs) (p < 0.05), and female patients (p < 0.05) on univariate analyses. Multiple linear regression analysis showed that RA, CTDs and admission for revision TKA were independent risk factors for preoperative DVT.
A high prevalence of preoperative DVT was found in patients admitted to hospital for TKA. Admission to the hospital for RA, CTDs and revision TKA were risk factors for preoperative DVT.
本回顾性研究的目的是调查全膝关节置换术（TKA）住院患者无症状深静脉血栓形成（DVT）的患病率及DVT风险。
2003年9月至2013年12月，322例行TKA的住院患者符合本回顾性研究条件。通过多普勒超声确诊DVT。评估TKA术前患者下肢无症状DVT的患病率。调查术前DVT的危险因素以及患者背景和病史中DVT的相关性。
56例患者（17.4%）术前诊断为DVT，其中3例为近端DVT。单因素分析显示，翻修TKA患者（p<0.01）、类风湿关节炎（RA）患者（p<0.005）、结缔组织病（CTD）患者（p<0.05）和女性患者（p<0.05）DVT风险显著升高。多元线性回归分析显示，RA、CTD和翻修TKA入院是术前DVT的独立危险因素。
TKA住院患者术前DVT患病率较高。因RA、CTD和翻修TKA入院是术前DVT的危险因素。
