Trauma-induced pulmonary thromboembolism is the second leading cause of death in severe trauma patients. Primary fibrinolytic hyperactivity combined with hemorrhage and consequential hypercoagulability in severe trauma patients create a huge challenge for clinicians. It is crucial to ensure a safe anticoagulant therapy for trauma patients, but a series of clinical issues need to be answered first, for example, what are the risk factors for traumatic venous thromboembolism? How to assess and determine the status of coagulation dysfunction of patients? When is the optimal timing to initiate pharmacologic prophylaxis for venous thromboembolism? What types of prophylactic agents should be used? How to manage the anticoagulation-related hemorrhage and to determine the optimal timing of restarting chemoprophylaxis? The present review attempts to answer the above questions.

Patients with critical illness are at the high risk of venous thromboembolism (VTE), and the older the patient, the higher the incidence of VTE. Despite its poor prognosis, VTE is preventable. At present, although there are many consensus or guidelines on the prevention of VTE at home and abroad, there is still a lack of consensus or guidelines for the prevention of VTE in elderly patients with critical illness. In order to standardize the prevention of VTE in elderly patients with critical illness in China, Expert consensus on the prevention of venous thromboembolism for elderly patients with critical illness in China (2023) was developed by Critical Care Medicine Division of Chinese Geriatric Society and Zhejiang Provincial Clinical Research Center for Critical Care Medicine. Members of the working group consulted relevant domestic and foreign guidelines, integrated evidence-based medical evidence and clinical experience, formed the draft consensus, submitted it to the expert group for discussion for many times, revised it for many times, and finally sent it to the expert group in the form of electronic questionnaire, and the expert gave a comprehensive score according to the theoretical basis, scientific nature and feasibility of the consensus items. The recommendation strength of each item was determined, and 21 recommendations were finally formed to provide reference for the prevention of VTE in elderly patients with critical illness.

PURPOSE: Static progressive stretch (SPS) can be applied to treat chronic joint stiffness. However, the impacts of subacute application of SPS to the distal lower limbs, where deep vein thrombosis (DVT) is common, on venous thromboembolism remain unclear. This study aims to explore the risk of venous thromboembolism events following subacute application of SPS. METHODS: A retrospective cohort study was conducted on patients diagnosed with DVT following a lower extremity orthopedic surgery before being transferred to the rehabilitation ward from May 2017 to May 2022. Patients with unilateral lower limb comminuted para-articular fractures, transferred to rehabilitation ward for further treatment within 3 weeks after operation, followed up more than 12 weeks since initial manual physiotherapy, and diagnosed DVT by ultrasound before rehabilitation course were included in the study. Patients with polytrauma, without evidence of previous peripheral vascular disease or incompetence, had medication for thrombosis treatment or prophylaxis before the operation, detected with paralysis due to nervous system impairment, infected after operation during the regime, or with acute progression of DVT were excluded. The included patients were randomized to the standard physiotherapy and the SPS integrated groups for observation. Associated DVT and pulmonary embolism data were collected during the physiotherapy course to compare the groups. SSPS 28.0 and GraphPad Prism 9 were used for data processing. A p < 0.05 was set significant difference. RESULTS: In total of 154 patients with DVT participating in this study, 75 of them were treated with additional SPS for postoperative rehabilitation. The participants in the SPS group showed improved range of motion (12.3° ± 6.7°). However, in the SPS group, there was no difference in thrombosis volume between the start and termination (p = 0.106, p = 0.787, respectively), although difference was seen intra-therapy (p < 0.001). Contingency analysis revealed the pulmonary embolism incidence (OR = 0.703) in the SPS group compared to the mean physiotherapy. CONCLUSION The SPS technique is a safe and reliable option to prevent potential joint stiffness without aggravating the risk of distal DVT for postoperative patients suffering from relevant trauma.

Venous thromboembolism is a common vascular disease with clinically high morbidity and mortality. Prevention and treatment strategies should be based on risk stratification. Anticoagulation remains the mainstay of therapy for patients with venous thromboembolism. More evidence-based studies should be performed to establish the strategy of prevention and treatment for venous thromboembolism in China.

Cancer is an acquired thrombophilic condition manifested by increased incidence of venous and arterial thromboembolic complications. Despite progress that has been achieved in treatments over the recent years, thromboembolism remains a major complication in patients with breast cancer; it is accompanied by significant morbidity and mortality. Approximately, 1% of breast cancer patients develop venous thromboembolism within 2 years with the highest incidence occurring in the 6 months post diagnosis. Metastatic disease and their comorbidities are the strongest predictors of the development of thrombotic event. The diagnosis of venous thromboembolism is associated with a higher risk of death within 2 years of diagnosis. Thromboembolic events in cancer patients range from abnormal laboratory coagulation tests without specific symptoms to massive thomboembolism and disseminated intravascular coagulation. The underlying pathophysiology is complex and includes the prothrombotic properties of cancer cells, which can be enhanced by anticancer treatment modalities, such as surgery, hormonal agents, and chemotherapy. Primary thromboprophylaxis in cancer patients should be individualized according to risk. For secondary prevention, several clinical studies have shown that low molecular weight heparin has improved patients' compliance, cancer outcomes and overall survival. This review summarizes the available data on the pathogenesis and clinical approach of hemostatic changes in breast cancer.

BACKGROUNDVenous thromboembolism (VTE) is an important complication after major orthopedic surgery. Pharmaceutical methods represent the main strategy of VTE prevention. The use of aspirin in VTE prevention is still controversial worldwide, especially in China. The purpose of this study was to evaluate the role of aspirin combined with mechanical measures in the prevention of VTE after total knee arthroplasty (TKA).

METHODSBetween January 2012 and May 2013 and in accordance with the inclusion criteria, 120 patients undergoing TKA were randomly allocated to two groups. To prevent VTE, patients in group A received aspirin combined with mechanical measures postoperatively, while patients in group B received low-molecular-weight heparin (LMWH) sodium and rivaroxaban sequentially in combination with mechanical measures postoperatively. All surgeries were performed by one surgeon using a posterior-stabilized cemented prosthesis. The two groups were followed up and compared for the incidence of deep vein thrombosis (DVT) by duplex ultrasound scan and clinical VTE events. The adverse events, the blood loss index, and the cost of VTE prevention were also compared.

RESULTSDVT was detected in 10 of 60 patients in group A (16.7%, 95% CI: 7.3%-26.1%) compared with 11 of 60 in group B (18.3%, 95% CI: 8.5%-27.8%) (P = 0.500). There is no statistical evidence supporting the inferior effect of aspirin in preventing DVT as compared with the other medications. There were no cases of symptomatic VTE or death during the follow-up period. Area of ecchymosis was lower in group A than in group B, and the differences were statistically significant. Patients in group A had the lower blood loss index as compared with patients in group B. No transfusion cases were found in both groups. The differences were statistically significant. The cost of VTE prevention analysis indicated a cost reduction using aspirin in group A compared with using LMWH and rivaroxaban in group B.

CONCLUSIONAspirin combined with mechanical measures had a good effect on prevention of VTE after TKA and resulted in lower cost, less blood loss, and less subcutaneous ecchymosis.

BACKGROUND: Aspirin has demonstrated safety and efficacy for venous thromboembolism (VTE) prophylaxis following total hip arthroplasty (THA); however, inconsistent dose regimens have been reported in the literature. This study aimed to evaluate and compare the safety and efficacy of 100 mg aspirin twice daily with rivaroxaban in VTE prophylaxis following THA. METHODS: Patients undergoing elective unilateral primary THA between January 2019 and January 2020 were prospectively enrolled in the study and randomly allocated to receive 5 weeks of VTE prophylaxis with either oral enteric-coated aspirin (100 mg twice daily) or rivaroxaban (10 mg once daily). Medication safety and efficacy were comprehensively evaluated through symptomatic VTE incidence, deep vein thrombosis (DVT) on Doppler ultrasonography, total blood loss (TBL), laboratory bloodwork, Harris hip score (HHS), post-operative recovery, and the incidence of other complications. RESULTS: We included 70 patients in this study; 34 and 36 were allocated to receive aspirin and rivaroxaban prophylaxis, respectively. No cases of symptomatic VTE occurred in this study. The DVT rate on Doppler ultrasonography in the aspirin group was not significantly different from that in the rivaroxaban group (8.8% vs. 8.3%, χ2 = 0.01, P = 0.91), confirming the non-inferiority of aspirin for DVT prophylaxis (χ2 = 2.29, P = 0.01). The calculated TBL in the aspirin group (944.9 mL [658.5-1137.8 mL]) was similar to that in the rivaroxaban group (978.3 mL [747.4-1740.6mL]) (χ2 = 1.55, P = 0.12). However, there were no significant inter-group differences in HHS at post-operative day (POD) 30 (Aspirin: 81.0 [78.8-83.0], Rivaroxaban: 81.0 [79.3-83.0], χ2 = 0.43, P = 0.67) and POD 90 (Aspirin: 90.0 [89.0-92.0], Rivaroxaban: 91.5 [88.3-92.8], χ2 = 0.77, P = 0.44), the incidence of bleeding events (2.9% vs. 8.3%, χ2 = 0.96, P = 0.33), or gastrointestinal complications (2.9% vs. 5.6%, χ2 = 1.13, P = 0.29). CONCLUSION: In terms of safety and efficacy, the prophylactic use of 100 mg aspirin twice daily was not statistically different from that of rivaroxaban in preventing VTE and reducing the risk of blood loss following elective primary THA. This supports the use of aspirin chemoprophylaxis following THA as a less expensive and more widely available option for future THAs.
