Right atrial thrombus, junctional tachycardia, and critical lower limb ischemia: three rare complications of severe acute respiratory syndrome coronavirus 2 infection

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can engender multi-system inflammatory syndrome. Its main symptoms are cardiovascular and thromboembolic problems that can develop into severe complications. The present case is about a 55-year-old patient who was admitted for critical ischemia of the right lower limb and necrosis of the right forefoot. The patient was infected with coronavirus disease 2019 (COVID-19) one month before her admission. The patient also has cardiovascular risks including type 2 diabetes and hypertension. The performance of ultrasounds revealed a thrombus in the right atrium and the pulmonary artery, and arteriography detected an occlusion of the right popliteal joint for which she had an endovascular recanalization and amputation of the right forefoot. This case highlights that SARS-CoV-2 infection could be considered a serious cardiovascular disease requiring cardiovascular explorations to initiate hospital management and avoid severe complications

Pseudoaneurysm of the subclavian artery following clavicle fracture due to blunt traumatism: a case report

The clavicle fractures are frequent, vascularinjuries associated with closed fractures of clavicleare rare. The pseudoaneurysms of the subclavianartery constitute an exceptional complication. Wereport a case of a 40-year-old who presented anexpanding hematoma of the right side of the neckafter a road traffic accident. Radiography of theright shoulder showed a midclavicular fracture. Anarterial doppler of vessels showed a circulatinghematoma in the contact of the right subclavianartery with a correct distality flow. Computedtomographic angiogram of the chest confirmed thediagnosis of a false aneurysm in the postvertebralportion of the right subclavian artery. Thetreatment was surgical and consisted of excision ofthe false aneurysm and a repair of the arterialinjury by an arterial patch, the clavicle was fixedwith a reconstruction plate and screws. Earlyintervention appears to be indicated due to the riskof thrombo-embolic complications. Endovascularrepair appears to be the preferred treatmentmodalities, due to a lower rate of cardiopulmonarycomplications, but it is reserved for much selectedcases
