As we continue to fight against the current coronavirus disease-2019 (COVID-19) pandemic, healthcare professionals across the globe are trying to answer questions surrounding how to best help patients with the up-to-date available science while awaiting the development of new therapies and mass vaccination. Since early in the pandemic, studies indicated a heightened risk of venous thromboembolism (VTE) in COVID-19 infected patients. There have been differing expert opinions about how to assess pretest probability of VTE in this patient population. This has been partly due to the high prevalence of respiratory failure in this patient population and the use of D-dimer as a prognostic test which is also frequently elevated in patients with COVID-19 in absence of VTE. Some experts have argued for an approach similar to usual care with testing if clinical suspicion is high enough. Some have argued for more routine screening at different points of care. Others have even suggested empiric therapeutic anti-coagulation in moderate to severely ill COVID-19 patients. In the following article, we review and summarize the most current literature in hopes of assisting clinicians in decision making and guidance for when to be concerned for VTE in COVID-19 patients. We also discuss research gaps and share pathways currently being used within our institution. 相似文献

Acute portomesenteric vein thrombosis is potentially lethal. In the present paper, a cirrhotic patient with a previous history of esophageal variceal bleeding presented with acute occlusive portomesenteric vein thrombosis, but achieved complete recanalization by low-molecular-weight heparin followed by rivaroxaban. Notably, no bleeding episode occurred during anticoagulation therapy. This case supported early initiation of anticoagulation in such patients. 相似文献

目的 探讨临床药师在急性下肢深静脉血栓患者个体化治疗中的作用。 方法 对南京鼓楼医院血管外科2018年8月收治的8例急性下肢深静脉血栓患者的治疗过程进行分析,结合临床药学知识制定导管接触性溶栓及抗凝用药方案,对患者实施全程药学监护。 结果 溶栓治疗期间,患者血浆纤维蛋白原水平呈明显下降趋势,血浆D-二聚体水平呈先升高后降低的趋势,血小板未见明显下降趋势;8例患者在溶栓治疗过程中,2例出现轻微牙龈出血后自行止血,1例出现血尿,停止溶栓治疗后改为口服抗凝药,血尿现象消失。患者预后改善明显,血栓完全溶解,静脉恢复畅通,用药安全得到有效保障。 结论 临床药师在导管接触性溶栓联合抗凝治疗急性下肢深静脉血栓患者的个体化用药监护方面发挥了积极作用。 相似文献

Direct-acting oral anticoagulants (DOACs) have emerged as safer, easier-to-manage alternatives to traditional vitamin K antagonists and are used increasingly because they require no monitoring, have a wider therapeutic window, and react less with other drugs. However, there is little consensus on optimal perioperative management when these drugs are used in dermatologic surgery. This article describes the characteristics of DOACs and reviews current evidence on their use in this setting. 相似文献

The authors describe a case of a patient admitted with a pre‐syncopal episode and precordial discomfort, and whose cardiac ultrasound performed in the Emergency Room was suggestive of Pulmonary Embolism. The patient was submitted to fibrinolytic therapy after cardiac arrest. The computerized tomography done after this episode not only confirmed the presence of pulmonary embolism but had also shown a Stanford Type B Aortic Dissection. The option was to maintain the therapeutic anticoagulation, having the patient evolved favourably. 相似文献
