ABSTRACT
Presentation of a 62-year-old man with baseline chronic obstructive pulmonary disease admitted to the hospital with dyspnea and newly diagnosed COVID-19 infection. CT scan of the chest was obtained to rule out pulmonary embolism. This revealed a mural thrombus of the inner curvature of the aortic arch with a floating component. Therapeutic full dose anticoagulation was initiated in combination with close clinical observation and treatment for modest hypoxia. He did well for 1 month and then returned with ischemic rest pain of the right foot. Angiography revealed thrombosis of all 3 tibial arteries in the right leg. Percutaneous mechanical thrombectomy with tissue plasminogen activator injection and angioplasty was performed with success in 1 tibial artery to achieve in line flow to the foot. After continued anticoagulation, the remainder of the tibial arteries autolysed and the aortic thrombus was noted to be resolved 4 months later. A brief pathophysiology discussion is included.
ABSTRACT
The Coronavirus Disease 2019 (COVID-19) pandemic has rapidly progressed, resulting in significant global morbidity and mortality. Predominantly affecting the respiratory tract, it has been found to be associated with extrapulmonary manifestations such as coagulopathies. We hereby report a case of an elderly man with no predisposing risk factors or history of hypercoagulable disorder who presented with acute onset abdominal pain and was diagnosed with portal vein thrombosis and splenic infarct two weeks following mild COVID-19. Incidentally, the patient was also noted to have aortic thrombosis. The patient was treated with therapeutic anticoagulation with complete resolution in his symptoms. Our case highlights a high risk of coagulopathy following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
ABSTRACT
A variable clinical presentation is emerging as a hallmark of the novel SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). In addition to hypoxic respiratory failure, multiorgan dysfunction, and septic shock, significant thromboembolic complications posited to result from diffuse coagulopathy have been associated with this viral infection. We report on a unique primary manifestation of SARS-CoV-2 infection presenting as acute limb ischemia and aortic mural thrombosis without clinical evidence of pulmonary disease. Despite our best attempts at limb salvage with therapeutic anticoagulation, emergent aortoiliac and distal embolectomy, the patient developed bilateral dry gangrene and ultimately required lower extremity amputations.
ABSTRACT
Since the outbreak of the COVID-19 pandemic, increasing evidence suggests that infected patients present a high incidence of thrombotic complications. We report a 67-year-old-woman admitted for severe acute respiratory syndrome coronavirus 2 infection. Chest CT images showed bilateral ground glass opacities, bilateral pulmonary embolism, right ventricular clot in transit and 2 thoracic aortic mural thrombus. Therapy was initiated with subcutaneous low-molecular-weight heparin, and the patient was discharged at 20 days asymptomatic. Complete resolution of the aortic thrombus was observed in a 1-month surveillance CT angiogram. Our case illustrates vascular complications in a COVID-19 patient and its effective treatment with anticoagulation.
