彩色多普勒超声检查对骨科大手术后下肢深静脉血栓形成的临床意义

摘要

ObjectiveTo explore the clinical significance of color Doppler ultrasound towards lower deep venous thrombosis after major orthopedic surgery.Methods532 patients who received major orthopedic surgery from January 2010 to December 2013 were selected as research subjects. Their conditions of deep venous thrombosis 1 week and 2 weeks after the major orthopedic surgery were analyzed via color Doppler ultrasound. Results Among the 532 patients examined by the color Doppler ultrasound, deep venous thrombosis was detected in 208 patients after the surgery, and the incidence reached 39.10%. Thrombosis in unilateral limb was detected in 172 patients, accounting for 82.69% of the total patients with thrombosis; deep venous thrombosis in bilateral limbs was detected in 36 patients, accounting for 17.31% of the total; 166 patients were detected with the symptom 1 week after the surgery, accounting for 79.80% of the total. Patients detected with the symptom 2 weeks after the surgery accounted for 18.75% of the total.Conclusion The peak period for the formation of deep venous thrombosis is 1 week after the major orthopedic surgery. The color Doppler ultrasound has the advantages of being non-invasive, accurate and highly sensitive, and is suggested to be the first choice of examining deep venous thrombosis after major orthopedic surgery.%目的：探讨彩色多普勒超声检查骨科大手术后下肢深静脉血栓形成的临床意义。方法选取我院2010年1月～2013年12月行骨科大手术的532例患者作为研究对象，通过彩色多普勒超声检查分析骨科大手术后1周、2周下肢深静脉血栓形成的发生情况。结果经彩色多普勒超声检查，532例患者术后检查出208例下肢深静脉血栓形成，发生率达到39.10%，单侧肢体发生血栓的有172例，占82.69%；双侧肢体同时有深静脉血栓形成的有36例，占总血栓患者的17.31%；术后1周查出下肢深静脉血栓形成的患者有166例，占总病例的79.80%。第2周后检出下肢深静脉血栓形成患者占18.75%。结论骨科大手术后1周时间是下肢深静脉血栓形成较高的时期，彩色多普勒超声检查具有无创、准确以及敏感度高的特点，应作为骨科大手术后诊断下肢深静脉血栓的首选。
