Highlights
Clinical signs are not useful for detecting DVT in critically ill COVID-19 patients
DVT occurs despite full dose anticoagulation in critically ill COVID-19 patients
Severe COVID-19 patients present a high prevalence of bilateral DVT
Background
Direct oral anticoagulants (DOAC) are an attractive alternative over vitamin K antagonists. They have several advantages in primary and secondary prevention of thromboembolisms due to atrial fibrillation, as well as in prevention and treatment of thromboembolic venous disease. They have fast onset action, do not need laboratory controls in patients with normal renal function, and they have practically no interference with the patient’s diet or medications. The strongest objection to their use was the lack of reversal agents that could be used in case of life-threatening haemorrhage or the need for emergency surgery. Dabigatran was the first DOAC to have its own specific reversal agent: idarucizumab, a monoclonal antibody.
Case summary
We report here the case of a patient undergoing treatment with dabigatran that suffered an expansive subdural haematoma secondary to a cranial injury. The condition was life-threatening and required emergency surgery. Anticoagulation was successfully reversed with idarucizumab.
Discussion
Emergency surgery in patients in treatment with DOAC is associated with an increased risk of bleeding. With the use of a specific antidote to block the action of the anticoagulant, as in the case of idarucizumab with dabigatran, the risk of complications during and after emergency surgery is reduced. This is the first case report with which the successful use of idarucizumab in Latin America is documented.
Background: The treatment of acute coronary syndrome (ACS) using percutaneous coronary intervention (PCI) is a frequent intervention with a high economic impact. Objective: This study investigates the resource use and cost of PCI in Mexico where heart disease is a leading cause of death, and a large segment of the population does not have formal healthcare coverage. Methods: This retrospective observational study obtained resource utilization data from patient files and itemized costs from the pharmacy registry at the National Institute of Cardiology. Patients were aged >18 years, diagnosed with ACS, and treated with PCI and secondary prophylaxis with aspirin plus clopidogrel or prasugrel. Patients had a follow-up of >12 months at the institute. Statistical analysis was descriptive. Results: The sample included 156 patients (mean age: 58.66 years; male: 77.9%). Patients were diagnosed with ST segment elevation myocardial infarction (STEMI), non-ST segment elevation myocardial infarction, and unstable angina 64.9%, 27.2%, and 7.9%, respectively.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
