目的:探讨股骨骨折患者下肢深静脉血栓形成（DVT）的流行病学特征。方法:回顾性分析2019年1月至12月期间河北医科大学第三医院收治的2 571例股骨骨折患者资料。男1 079例，女1 492例；年龄为14~96岁，平均67.1岁。骨折部位：股骨颈骨折1 158例，股骨转子间骨折951例，股骨干骨折309例，股骨髁骨折153例。2 414例患者行手术治疗，157例患者采用非手术治疗。手术患者术前及术后每周，非手术患者入院48 h内及住院期间每周均行双下肢彩色多普勒超声检查，判断DVT的发生情况。记录股骨不同部位骨折后DVT的发生率及发生位置。结果:股骨骨折患者DVT发生率为35.5%（913/2 571），近端DVT发生率为5.3%（135/2 571），远端DVT发生率为30.3%（778/2 571）。股骨颈骨折、股骨转子间骨折、股骨干骨折、股骨髁骨折患者DVT的发生率分别为28.8%（334/1 158）、44.7%（425/951）、30.7%（95/309）、38.6%（59/153），近端DVT发生率分别为2.7%（31/1 158）、5.6%（53/951）、9.7%（30/309）、13.7%（21/153），远端DVT发生率分别为26.2%（303/1 158）、39.1%（372/951）、21.0%（65/309）、24.8%（38/153）。股骨骨折患者股静脉及以上部位、腘静脉、胫腓静脉、肌间静脉DVT发生率依次2.3%（60/2 571）、2.9%（75/2 571）、6.4%（165/2 571）、23.8%（613/2 571）。结论:股骨骨折患者DVT发生率较高，而且发生肺栓塞风险性大的近端DVT更易发生于股骨髁骨折患者。“,”Objective:To investigate the epidemiological characteristics of lower extremity deep vein thrombosis (DVT) in patients with femoral fracture.Methods:Retrospectively analyzed were the data of 2,571 patients with femoral fracture who had been treated at the Third Hospital of Hebei Medical University from January 2019 to December 2019. There were 1,079 males and 1,492 females, aged from 14 to 96 years (average, 67.1 years). There were 1,158 femoral neck fractures, 951 femoral intertrochanteric fractures, 309 femoral shaft fractures, and 153 femoral condylar fractures. 2,414 patients were treated surgically while 157 patients non-surgically. Color Doppler ultrasonography of both lower extremities was performed to determine the occurrence of DVT before operation and every week after operation for patients undergoing surgical treatment, and within 48 hours after admission and every week during hospitalization for those undergoing non-surgical treatment. The incidence and location of DVT were recorded for different femoral fractures.Results:The incidence of DVT in this cohort was 35.5%(913/2,517), that of proximal DVT 5.3%(135/2,571), and that of distal DVT 30.3% (778/2,571). In patients with femoral neck fracture, femoral intertrochanteric fracture, femoral shaft fracture and femoral condylar fracture, the incidence of DVT was respectively 28.8% (334/1,158), 44.7% (425/951), 30.7% (95/309) and 38.6% (59/153), the incidence of proximal DVT was respectively 2.7% (31/1,158), 5.6%(53/951), 9.7% (30/309) and 13.7% (21/153), and the incidence of distal DVT was respectively 26.2% (303/1,158), 39.1% (372/951), 21.0% (65/309) and 24.8%(38/153). The incidence of DVT in the femoral vein and above, popliteal vein, tibiofibular vein and intermuscular vein in this cohort was respectively 2.3%(60/2,571), 2.9%(75/2,571), 6.4%(165/2,571) and 23.8%(613/2,571).Conclusions:The incidence of DVT may be high in patients with femoral fracture, and the proximal DVT with a high risk of pulmonary embolism may occur more in patients with femoral condylar fracture.
