Paradoxical brain embolism shadowing massive pulmonary embolism
Patent foramen ovale is frequently observed in the general population. In case of massive pulmonary embolism, the sudden increase in the right heart cavity's pressure may cause a right-to-left shunting across this foramen, which could be associated with conflicting outcomes. Herein, we report a case of reversible cardiac arrest preceded by seizures, and followed by hemodynamic stability without any vasopressor. A brain CT-scan showed a limited ischemic stroke. Initial echocardiographic assessment revealed an acute cor pulmonale and a right-to-left intracardiac shunt across a large patent foramen ovale, suggesting the diagn...

COVID-19 infection with extensive thrombosis: A case of phlegmasia cerulea dolens
Reports have been published from multiple countries regarding increased thrombus formation in COVID-19 patients, especially critically ill patients. These include DVT formation as well as pulmonary embolism and stroke. Currently, the exact mechanism as to why COVID-19 patients are at higher risk for thrombotic complications has not been determined. It has been thought to be due to endothelial injury, blood stasis or a hypercoagulable state . To our knowledge this is the first reported case of phlegmasia cerulea dolens in a patient diagnosed with COVID-19.

Priapism in a patient with coronavirus disease 2019 (COVID-19): A case report
Thromboembolic complications related to SARS-CoV-2 have been extensively reported. They include deep vein thrombosis, pulmonary embolism, ischemic stroke, and acute coronary syndrome. Penile thrombosis has not been reported as a thrombotic complication of SARS-CoV-2 infection with hypercoagulability.Here we describe a case of priapism as a thromboembolic complication in a patient with COVID-19 who recovered from acute respiratory distress syndrome (ARDS). We discuss the underlying pathophysiological mechanisms mainly related to an hypercoagulability state.
