Iatrogenic Aortic Intramural Hematoma: Guidance to Intraoperative Decision Making: A Case Report.
Aortic intramural hematoma (IMH) is a collection of blood within the aortic wall without an identifiable intimal tear. It belongs to the spectrum of acute aortic syndrome (AAS) which also includes aortic dissection (AD), a well-defined entity. ⋯ But with recent advances in imaging, certain features of IMH have been identified that affect the natural course of IMH. We report a unique case of iatrogenic IMH complicating a routine coronary artery bypass graft surgery (CABG) and how imaging guided intraoperative decision making toward conservative management.

Dual RVAD-ECMO Circuits to Treat Cardiogenic Shock and Hypoxemia Due to Necrotizing Lung Infection: A Case Report.
Utilization of venoarterial extracorporeal membrane oxygenation (VA-ECMO) is expanding, but dual VA-ECMO circuits to treat cardiogenic shock with refractory hypoxemia is unreported. We describe the case of combined cardiogenic and distributive shock due to necrotizing pulmonary blastomycosis. ⋯ After 4 months on support, he underwent successful heart-lung-kidney transplantation. Dual ECMO circuits are technically feasible and may be advantageous in specific circumstances of high pulmonary shunting resulting in excessive hypoxemia unbalanced with appropriate oxygen delivery.

Venoarterial extracorporeal membrane oxygenation (vaECMO) is a well-established treatment option for severe cardiogenic shock of various etiologies. Although trials have explored weaning strategies, a brief and conclusive overview is lacking. We present the different aspects of weaning and provide an evidence- and experienced-based guide for clinicians managing patients under vaECMO in the preweaning, weaning, and postweaning phases.

Patient care duties will expose health care workers to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Many are concerned about subsequent household exposure to their families, particularly those family members with high risk of complications or mortality, potentiating additional community spread. ⋯ The design is simple, expedient, and can be built with locally sourced inexpensive supplies. A viewing and access window facilitates safe family interaction and decreases the emotional costs of isolation while providing a route to pass items as necessary.

Case Reports
Systemic Air Embolism in a Patient With Lung Lesion Undergoing Neurosurgery in Sitting Position: A Case Report.
Systemic air embolism secondary to venous air embolism is a known complication of sitting position surgery. However, the possibility of an isolated systemic air embolism must be considered, especially in patients with preexisting lung disease receiving positive pressure ventilation. These patients may benefit from a comprehensive preoperative evaluation and advanced intraoperative monitoring. We report a case of a 53-year-old woman with chronic obstructive airway disease and a preexisting fibrocavitary lung lesion, who developed isolated air entrainment into the left heart during sitting position surgery.
