Purpose: The actual incidence of deep vein thrombosis (DVT) in femoral neck fractures is underestimated. This study aimed to investigate the incidence of DVT in the lower extremities after femoral neck fracture before and after operation. Methods: The clinical data of patients with femoral neck fractures treated at Xi’an Honghui Hospital between July 1, 2016, and December 31, 2018, were collected. The patients were examined with ultrasonography before and after operation and divided into thrombosis and non-thrombosis groups according to their ultrasonographic results. The incidence of DVT was reported as a percentage. Results: The incidence rates of preoperative and postoperative DVT were 32% and 56%, respectively. DVT on the uninjured side constituted 45% of all preoperative DVT and 43% of all postoperative DVT. Peripheral DVT constituted 90% and 84% of all preoperative and postoperative DVT, respectively. Diabetes was an independent risk factor of preoperative DVT. Blood loss was an independent risk factor of postoperative DVT, and open reduction and internal fixation surgical procedure was independent protective factor of postoperative DVT as compared with hemiarthroplasty and total hip replacement. Conclusions: The incidence rates of preoperative and postoperative DVT in the patients with femoral neck fracture were high, and orthopedists should pay more attention to DVT as a complication.

This study aimed to investigate deep vein thrombosis (DVT) in patients with lower extremity fractures who received anticoagulation treatment in the perioperative stage. We collected the patients’ clinical data and diagnosed DVT using Doppler ultrasonography. Preoperative, postoperative, and 1-month postoperative examinations were performed. The patients were divided into thrombosis and non-thrombosis groups according to ultrasonographic findings. A total of 404 patients were included in the study. The preoperative, postoperative, and 1-month postoperative incidence rates were, respectively, 35%, 55%, and 40% for DVT and 12%, 22%, and 20% for DVT in the uninjured contralateral lower extremity. The incidence of perioperative DVT decreased over time from 223 (55%) to 161 (40%). Multivariate analysis revealed that the independent risk factors for preoperative that of DVT were age (odds ratio [OR]: 1.03; 95% CI: 1.01-1.04; P = .000); postoperative that of DVT were age (OR: 1.04; 95% CI: 1.03-1.05; P = .000), blood loss (OR: 1.001; 95% CI: 1.000-1.002; P = .018), and American Society of Anesthesiologists classification (OR: 2.07; 95% CI: 1.16-3.72; P = .014); and 1-month postoperative that of DVT were age (OR: 1.05; 95% CI: 1.03-1.07; P = .000), respectively. In conclusion, the incidence of perioperative DVT decreased over time in patients who received anticoagulation treatment. Age was an important risk factor for perioperative DVT.

“…The proposed diagnostic strategies combine the clinical probability score with D-dimer test and compression sonography. [64][65][66][67][68][69][70][71][72] The clinical risk assessment score is based on patient history, symptoms and physical examination. A history of malignancy, previous DVT, recent immobilization, recent surgery, and difference in calf diameter were the most useful criteria for assessing the clinical probability of DVT.…”

Current approaches and controversial issues in the diagnosis of deep vein thrombosis via duplex Doppler ultrasound

Duplex and color Doppler sonography (DUS) is currently the technique of choice for the diagnosis of deep venous thrombosis (DVT) in symptomatic patients, because it has proven safe and cost-effective, with a very high sensitivity and specificity (96% and 98%, respectively) for the diagnosis of proximal DVT. Several issues regarding its method and clinical indications remain controversial, however. Although isolated calf vein thrombosis does not seem to have a significant adverse outcome in the short term, scanning the calf only in patients with localized symptoms or signs is cost-effective. Bilateral examination is indicated in high-risk patients or when screening asymptomatic patients. When negative, a complete DUS examination of the proximal and distal veins, at least down to the level of the popliteal trifurcation, allows withholding anticoagulant therapy without the risk of major complications. This examination may be repeated if signs or symptoms worsen. Some populations of asymptomatic patients at high risk of DVT may benefit from DUS screening. Bilateral DUS examination of lower limb veins should be performed as the initial examination in the workflow of pulmonary embolism only in patients with risk factors for DVT. Recurrent thrombosis is a challenging diagnosis for all imaging modalities. A diagnostic strategy combining clinical probability score and D-dimer test may refine the selection of patients. The pitfalls and limitations of venous DUS are related to vein anatomy, flow changes, technical issues, and operator expertise.
