Incidence and risk factors for deep venous thrombosis of lower extremity after surgical treatment of isolated patella fractures

Abstract Background Limited information exists on the incidence of postoperative deep venous thromboembolism (DVT) in patients with isolated patella fractures. The objective this study was to investigate and locations thrombosis lower extremity who underwent fractures identify associated risk factors. Methods Medical data 716 hospitalized collected. had acute were admitted at 3rd Hospital Hebei University between January 1, 2016, February 31, 2019. All met inclusion criteria. collected using inpatient record system, which included patient demographics, patient’s bad hobbies, comorbidities, past medical history, fracture surgery-related factors, hematological biomarkers, total hospital stay, preoperative stay. Doppler examination conducted for diagnosis DVT. Univariate analyses multivariate logistic regression used independent Results Among patients, DVT confirmed 29 cases, indicating an 4.1%. involved bilateral limbs (injured uninjured) one (3.4%). superficial femoral common vein 1 case (3.4%), popliteal 6 cases (20.7%), posterior tibial 11 (37.9%), peroneal (37.9%). median interval surgery 4.0 days (range, 1.0-8.0 days). Six variables identified be factors age category (> 65 years old), OR, 4.44 (1.34-14.71); arrhythmia, 4.41 (1.20-16.15); intra-operative blood loss, 1.01 (1.00-1.02); stay (delay each day), 1.43 (1.15-1.78); surgical duration, 1.04 (1.03-1.06); LDL-C 3.37 mmol/L), 2.98 (1.14-7.76). Conclusion Incidence is substantial. More attentions should paid prophylaxis Identification can help clinicians recognize population, assess DVT, develop personalized strategies.
