ABSTRACT
The coronavirus disease 2019 pandemic has impacted millions of people worldwide. This novel virus has a variety of presentations and complications. Notably, patients with this infection have an associated coagulopathy, presenting with symptoms such as gastrointestinal bleeds, deep vein thrombosis, ischemic cerebrovascular events, and pulmonary embolism. Although there are documented cases of venous thromboembolism in patients with coronavirus disease 2019, the authors present an interesting case of upper extremity arterial thromboembolism in a 75-year-old patient surgically treated for arterial thrombus removal. We also discuss diagnosis, medical management, and surgical approach to an upper extremity arterial thromboembolism in a patient with coronavirus disease 2019, to highlight the challenges of hypercoagulability in such patients.
ABSTRACT
Thrombosis is one of the major underlying pathogenetic mechanisms leading to increased morbidity and mortality among COVID-19 patients. Thromboembolic events as well as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are the major causes of death in this continued pandemic. While elevated D-dimer level suggests worse thrombotic outcomes, levels at which benefits of anticoagulation outweigh the bleeding risk is yet to be determined. In this report, we present a case of a 72-year-old man with COVID-19 presented with confusion and subsequently developed acute hypoxic respiratory failure. On hospital day 7, patient developed extensive peripheral arterial thrombosis with acute rise of D-dimer from 800 to 14,899 ng/ml. He was treated with heparin drip and underwent urgent brachial, radial and ulnar embolectomy under general anesthesia. In this report, we also discuss the pathogenetic mechanisms and management of thromboembolism in COVID-19 patients, highlighting the role of early detection and aggressive therapeutic interventions that could be life and / or limb saving strategy.
