Abstract
Abdominal Aortic Thrombosis Complicating COVID-19 Pneumonia
Highlights
MRI can demonstrate a high signal in T1-weighed scans for the presence of paramagnetic methemoglobin.[5,6]
Asymptomatic at an early stage, the thrombus carries an important risk of peripheral embolization, of «saddle» embolus to the aortic bifurcation, or of progressive spreading inside the aorta and one of its branches.[7]
We remark the important role of atherosclerosis, which can complicate with rupture of a vulnerable plaque, ulceration of the surrounding intima, directly leading to a mural thrombosis
Summary
MRI can demonstrate a high signal in T1-weighed scans for the presence of paramagnetic methemoglobin.[5,6] asymptomatic at an early stage, the thrombus carries an important risk of peripheral embolization, of «saddle» embolus to the aortic bifurcation, or of progressive spreading inside the aorta and one of its branches.[7] In presence of an aortic graft or an endoprosthesis, this complication can progress until to completely obstruct the aortic lumen.
