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.
