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.

Thalassemia is the most common human hereditary hemolytic anemia. Due to splenomegaly and hypersp-lenism, splenectomy can be used as a means of treatment for thalassemia. Various complications following splenectomy, however, especially thromboembolic complications are remarkable. This review summarizes the incidence, clinical manifestations and development time of thromboembolism. The pathogenesis of thromboembolism after splenectomy in thalassemia, such as abnormal platelet number and function, changes in red cell membrane, endothelial cell damage, dysfunction of other procoagulant and anticoagulant factors, and local factors associated with splenectomy are elaborated and the trategies to prevent and treat the thromboembolic events in thalassemia after splenectomy, including the attention to risk factors associated with splenectomy, a reassessment of splenectomy, regular blood transfusion to reduce the ratio of abnormal red blood cells, treatment with anticoagulant and antiplatelet drugs, application of hydroxyurea and stem cell transplantation are discussed.

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.

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.
