下肢深静脉血栓形成的临床诊断价值及危险因素

在连续２８２例临床拟诊为下肢急性深静脉血栓形成（ＤＶＴ）的有症状患者中，经超声静脉检查证实为ＤＶＴ者仅９７例（３４．４％）．表明临床表现只能提示、而不能可靠诊断ＤＶＴ。年龄（≥５５岁）、恶性肿瘤和近期（３个月内）手术史是ＤＶＴ的危险因素。与对照组相比，有上述各项危险因素的患者，ＤＶＴ检出率均显著增高（Ｐ＜０．０５）。

Clinical Diagnostic Value and Risk Factors of Acute Deep Vein Thrombosis in Lower Extremities

consecutive symptomatic patients suspected clinically of having lower extremity acute deep vein Thrombosis(DVT),the diagncois of DVT was verified by ultrasonic duplex scanning only in 97 cases(34.4%).Confirming that the clinical diaguosis of DVT is grossly inaccurate,some form of objective testing should be performed on all patients in whom the disease is suspected. Advancing age(≥55-year-old),malignancy and recent surgery(within three months)were found to be risk factors, because the patients with each of the three factors had a higher prevalence of DVT(39.2%,64.3%and 46.7%respectively) thnan those without(26.4% ,32.8%and 31.1% respectively,all P<0.05)
