Arterial thrombosis encountered during sars-cov2 infections is a rare complication with a poor prognosis compared to venous ones. They generally occur in severe and critical clinical forms of covid19 [1,2]. The physiopathology of arterial thrombosis, even if not completely understood highlights hypercoagulability and excessive inflammation as risk factors with a major role of the endothelial lesions in their occurrence. The presence of cardiovascular risk factors in patients infected with covid19 is also discussed as a predisposing factor for arterial thrombosis [2,3]. We report the case of a North African male patient hospitalized for acute respiratory distress syndrome (ARDS) secondary to covid19 pneumonia, complicated by the occurrence of multiple arterial thrombosis of the aorto-iliac axis with the rare finding of two free floating thrombus in the aorta and the right common iliac artery. Clinically, the patient had developed acute bilateral lower limb ischemia and multi-organ failure and the evolution was dramatic with rapid worsening of the patient...s health and eventually his death. Thromboembolic complications are frequent during covid19 infection but the aortic localization is very rare. Its diagnosis is difficult and it has a poor prognosis. Our objective through this case report is to increase knowledge about arterial thromboembolic events while discussing their link to the sars-cov2 viral infection., (© 2022 The Authors.

The Arteria lusoria or aberrant right subclavian artery (ARSA) constitutes one of the rarest malformations of the aortic arch, it can be associated with other congenital anomalies of the heart and large vessels, in particular the bi-carotid trunk or common origin of the carotid arteries (COCA) which is the presence of a single branch from the aorta giving off both right and left common carotid arteries. We report the case of a patient followed for severe mitral stenosis, and hospitalized for an ischemic cerebral vascular accident, a chest CT scan was performed in front of her clinical and biological degradation, which allowed the fortuitous discovery of an Arteria lusoria (aberrant retro- esophageal artery) associated with a Truncus bicaroticus., (© 2021 The Authors.)

Acute mesenteric ischemia (AMI) is due to a sudden decrease or interruption of mesenteric blood flow resulting in inadequate blood supply to the gastrointestinal tract. This causes ischemic and inflammatory lesions often progressing to necrosis in the absence of appropriate treatment. Vascular insufficiency may arise as a result of embolism or arterial thrombosis or venous thrombosis. We here report a rare case of mesenteric venous ischemia caused by coronavirus disease 2019 (COVID-19) in a 33-year-old man in whom diagnosis was based on ultrasound and, in particular, on computed tomography (CT)., Competing Interests: Les auteurs ne déclarent aucun conflit d´intérêts., (Copyright: Oussama Marsafi et al.)
