深静脉血栓形成103例临床分析

目的 提高对深静脉血栓形成（ＤＶＴ）和肺栓塞（ＰＥ）的认识，了解二者的关系。方法 对１０４３例ＤＶＴ病例做一回顾性分析。结果 ＤＶＴ与ＰＥ关系密切，ＤＶＴ病例中ＰＥ的发生率为４４．７％。有危险因素者占８８．３％，最常见的危险因素为长期卧床（２ ６．２％）

A clinical analysis of 103 cases of deep venous thrombosis

Objective To have a better understanding of deep venous thrombosis (DVT) and pulmonary embolism (PE) as well as their relationship. Methods Review of clinical data of 103 cases with DVT treated in Peking Union Medical College Hospital from 1983 to 1999. Results Of the 103 cases with DVT,46 were diagnosed as PE (44.7%) and 88.3% of the cases had risk factors. The most common risk factors were prolonged immobilization (26.2%), surgery (23.3%), hyperlipemia (21.4%), hypertension (19.4%), malignancy (13.6%), hyperhemoglobinemia (13.6%), heart disease (12.6%), trauma (9.7%) and femoral venous puncture (9.7%). The number of risk factors increased with increase of age. The most common clinical presentations of DVT were swelling (91.3%)and pain (58.3%)of calf and thigh. The most common site of DVT was femoral vein. Femoral vein thrombosis was the most common cause leading to PE. The initial diagnostic modality for DVT should be noninvasive testing. After anticoagulant therapy or thrombolytic therapy or surgery, mortality of DVT and PE in Peking Union Medical College Hospital was 6.5%. Conclusion It is essential to identify various risk factors and clinical presentations of DVT and to select suitable examination and treatment as early as possible.It will decrease the incidence and the mortality of PE.
