Abstract:
Objective To investigate the risk factors and clinical characteristics of deep venous thromboembolism (DVT) of the lower extremities in Chinese people. Methods The clinical manifestations and risk factors in 2742 DVT patients diagnosed by phlebography were retrospectively studied. Results DVT made up 22.39% of all the venous diseases of the lower extremity. The most common clinical presentations of DVT were swelling and pain (92. 34% ), varicose vein ( 32. 57% ), pigmentation (24. 95% ) and ulceration( 18.45% ). The left lower extremity was more frequently involved. The whole limb type was 60. 09%, 80. 23% DVT patients had identified risk factors including age over 40 years old (76. 29% ), history of major surgery ( 12. 18% ) and severe trauma ( 8.42% ), pregnancy and the puerperium ( 4. 87% ). The history of general surgery ( 26. 05% ), vascular surgery ( 23. 35% ), gynaecoiogy and obstetrics (20. 96% ), orthopaedics ( 16. 47% ) and urinary surgery (7.49%) was among the most common surgery. Primary hypercoagulable syndrome was identified in 0. 22% DVT patients. Conclusion DVT makes up 22. 39% of the disease of veins of the lower extremity. The most common clinical presentations of DVT were swelling and pain. The most common risk factors were age over 40 years, major surgery, severe trauma. Primary hypercoagulable syndrome is a heritage risk factor for DVT pathogenesis.
