Persistent false lumen (FL) perfusion with aneurysmal formation is common after thoracic endovascular aortic repair (TEVAR) for typical extended aortic dissection and is associated with poor outcomes. Endovascular FL embolization (FLE) has recently been tried for treatment of postdissection aortic aneurysm (PDAA). However, most reports address thoracic rather than abdominal FLE. In this study, we present the results of abdominal FLE in patients with residual patent abdominal FL following stent-graft repair for aortic dissection. ⋯ From our results, abdominal FLE is a safe procedure. However, covering all the re-entry tears is complex and the possibility of complete FL thrombosis is low. The abdominal aortic diameter appears to become enlarged in these patients. Continuous follow-up is necessary after FLE.

Orbital cellulitis is an infrequent but serious infectious complication of rhinosinusitis, most commonly seen in the pediatric population. Extension into the cavernous sinus, leading to further infection and thrombosis, is a rare but life-threatening complication. Although COVID-19 has been linked to an increased risk of venous thromboembolism, most cases involve extremity deep venous thrombosis or pulmonary embolism; reports of intracranial or jugular system thrombosis are rare. ⋯ We describe a case of a 17-year-old female patient with no significant medical history or thrombotic risk factors found to have orbital cellulitis and severe pansinusitis, complicated by multiple venous thromboses in the head and neck requiring emergent surgical intervention and pediatric intensive care admission. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Extensive head and neck venous thrombosis and intracranial abscesses are rare complications of pansinusitis and orbital cellulitis, and the thrombotic complications of COVID-19 are well documented. A delay in diagnosis and treatment can lead to potentially devastating consequences.

Observational StudyEchocardiography Before Extracorporeal Membrane Oxygenation in Refractory Respiratory Failure: SARS-CoV-2 Infection Versus Other Etiologies.
The study authors hypothesized that in patients with SARS-CoV-2, COVID-19-related refractory respiratory failure requiring extracorporeal membrane oxygenation (ECMO) support echocardiographic findings (just before ECMO implantation) would be different from those observed in patients with refractory respiratory failure from different etiologies. ⋯ The presence of RV dilatation and an altered coupling between RVe function and pulmonary vasculature (as indicated by TAPSE and/or sPAP) are associated strictly with COVID-19-related refractory respiratory failure needing ECMO support.
