Abstract
50 years old male presented with livid redness on both feet, predominantly left, accompanied with severe pain and coldness. Two weeks before, he admitted to hospital due to COVID-19 bronchopneumonia. Urgent abdominal and lower extremities contrast enhanced CT was performed, which showed mural thrombus of the abdominal aorta (AA) extending from below the left renal artery to the iliac bifurcation and total occlusion of the left and partial occlusion of the right crural arteries.
Interventional procedures are the first choice for initial emergency management, leaving surgery as a second and anticoagulant therapy as third option for treatment. Endovascular treatment is based on stent grafting. Covered stent graft was used to repair the AA and kissing stenting technique was used in the aortoilical part. The result was complete patency of AA and both iliacal arteries, with
improved clinical status. Mural thrombi are likely to occur in large vessels as the heart and descending aorta, and less commonly in the aortic arch or the AA, causing flow reduction. Their occurrence is a rare in the absence of hypercoagulative state or inflammatory, infectious, or
familial aortic ailments. In our case, Covid -19 is associate occurrence of thrombus in the AA, which throws out smaller thrombi in the peripheral circulation that causes critical limb ischemia (CLI).CT is the best modality for early diagnosis and endovascular treatment the least invasive treatment.
Mural aortic thrombus accompanied by CLI is an urgent medical condition which, if not diagnosed and treated on time, can result in limb amputation or death. Endovascular stenting is first choice of treatment in patients without previous vascular disease.
