OBJECTIVETo study the instance of deep venous thrombosis(DVT) complicated by preoperative lower extremity close fracture.

METHODSRetrospectively analyzed the clinical data of 54 patients with DVT (through color Doppler to final diagnosis) complicated by preoperative lower extremity close fracture from March 2008 to February 2009, and explored the concomitant reason of DVT. There were 23 males and 31 females with age for 23-95 years old.

RESULTSDVT including thrombus of ilio-venae external, thrombus of femoral vein, thrombus of popliteal vein, thrombus of posterior tibial veins and thrombus of soleus venae. The instance of DVT complicated by preoperative lower extremity close fracture: (1) The age of 23 cases (42.59%) more than 70 years. (2) 11 cases (20.37%) combined with syndrome, 2 cases had hypertension, 3 cases had hypertension and diabetes, 2 cases hypertension and cerbral infarction, 4 cases had hypertension, diabetes and coronary heart disease. (3) 10 cases (18.51%) were multi-fractures. (4) 28 cases (51.85%) occurred DVT at 7-14 days after lower extremity close fracture.

CONCLUSIONAdvanced age, complicating hypertension, diabetes, coronary heart disease, cerbral infarction, multi-fractures may be lead to DVT. Multitudinous DVT occurred at 7-14 days after fracture, as early as possible operation has important significance on prevention DVT to decrease risk of pulmonary embolism.
