全髋关节置换术围术期下肢深静脉血流动力学研究

目的 探讨全髋关节置换围术期下肢深静脉血流动力学改变及下肢深静脉栓塞(deep vein thrombosis,DVT)的早期诊断. 方法 对62例初次全髋关节置换术患者进行围术期的多普勒超声检查、血液流变学检测和血浆D-二聚体检测,在发生DVT及无DVT间对相关结果 进行统计学分析,以探讨DVT的早期诊断. 结果 多普勒超声检查发现8例并发DVT,并发DVT组术后血浆D-二聚体浓度显著高于术前,也显著高于未并发DVT组(P<0.05),血液流变学各项指标检测显示术后7 d显著性增高(P<0.05). 结论多普勒超声检查结合血浆D-二聚体和血液流变学检测有利于早期诊断DVT.

Hemodynamics of deep vein in lower limb during perioperative period of total hip arthroplasty

Objective To investigate hemodynamic changes of deep vein in lower limb during the perioperative period of total hip arthroplasty (THA) and early diagnosis of deep vein thrombosis (DVT). Methods Doppler ultrasound, hemorheology detection and plasma D-dimer testing were done on 62 patients treated with THA. Statistical analysis was carried out on the data of patients with or without DVT to study the early diagnosis of DVT. Results The results of Doppler ultrasound showed DVT in 8 patients. Compared with postoperative concentration of plasma D-dimer, the preoperative con-centration of plasma D-dimer was significandy higher in patients with or without DVT (P < 0.05). The levels of hemorheological indices were significantly increased at postoperative day 7 (P < 0.05). Con-clusions Doppler ultrasound combined with plasma D-dimer testing and hemorheology detection are helpful in early diagnosis of DVT.
