Prospective cohort study.
Operating room and hospital ward.
144 consecutive ASA physical status 1 and 2 patients who underwent elective total hip arthroplasty (THA; n=64) or total knee arthroplasty (TKA; n = 80).
Patients were allocated to two groups, those who developed DVT (DVT group) postoperatively and those who did not (no-DVT group). To examine the perioperative risk factors for DVT after THA or TKA, comparative analysis of the two groups was done.
Doppler US was performed on all patients from the bilateral femoral to lower limb to detect the existence of DVT postoperatively.
DVT was detected in 61 patients (42 % ), including three proximal DVT patients (2 % ). Preoperative elevated plasma D-dimer value [P = 0.0131, odds ratio (OR) 1.54, 95 % CI 1.10-2.17] and history of hyperlipidemia (P = 0.0453, OR 6.92, 95 % CI 1.04-46.00] were significant risk factors for the onset of DVT. A preoperative plasma D-dimer cutoff value as a diagnostic test was obtained as 0.85 ¦Ìg/mL.
A high preoperative plasma D-dimer value and/or history of hyperlipidemia were risk factors for DVT after THA or TKA.
