Magnetic resonance imaging is a promising tool to noninvasively detect arterial thrombosis. Measurement of SI and the characteristic visual appearance of the thrombus have the potential to define thrombus age.

In March 2020, the New York City metropolitan area became the epicenter of the United States' SARS-CoV-2 pandemic and the surge of new cases threatened to overwhelm the area's hospital systems. This article describes how an anesthesiology department at a large urban academic hospital rapidly adapted and deployed to meet the threat head-on. Topics included are preparatory efforts, development of a team-based staffing model, and a new strategy for resource management. While still maintaining a fully functioning operating theater, discrete teams were deployed to both COVID-19 and non-COVID-19 intensive care units, rapid response/airway management team, the difficult airway response team, and labor and delivery. Additional topics include the creation of a temporary 'pop-up' anesthesiology-run COVID-19 intensive care unit utilizing anesthesia machines for monitoring and ventilatory support as well as the development of a simulation and innovation team that was instrumental in the rapid prototyping of a controlled split-ventilation system and conversion of readily available BIPAP units into emergency ventilators. As the course of the disease is uncertain, the goal of this article is to assist others in preparation for what may come next with COVID-19 as well as potential future pandemics.

Introduction: Splenic rupture can be classified as traumatic, pathologic, or spontaneous. Spontaneous splenic rupture is rare, and accounts for only 1% of cases. Most cases of spontaneous splenic rupture involve a histopathologically abnormal spleen, but in rare cases, rupture of the spleen can occur in the absence of underlying disease or trauma. We present a case of delayed spontaneous splenic rupture in the postoperative setting following a partial nephrectomy.Case Description: A 54-y-old man presented with abdominal pain, dysuria, fever, and chills 1 week after a robotic left partial nephrectomy. An initial computed tomography scan showed no evidence of splenic injury, and he was admitted for suspected pyelonephritis. A computed tomography scan was obtained 4 d later for worsening pain and fever and revealed a 14-cm subcapsular hematoma of the spleen extending to the gastrohepatic ligament. He underwent an emergent angiogram and embolization of an actively bleeding splenic artery and inferior phrenic artery. A second embolization was required 2 d later to control ongoing bleeding. He then developed increased abdominal pain with nausea, vomiting, and continued leukocytosis secondary to a completely infarcted and necrotic spleen. A laparoscopic, hand-assisted splenectomy was performed successfully, and he was eventually discharged in stable condition. Conclusion:Spontaneous splenic rupture is extremely rare, particularly in the postoperative setting. It is possible that some of these cases are in fact secondary to occult trauma to the spleen during surgery. Prompt diagnosis and management, often with emergent splenectomy, is critical in these cases. Minimally invasive surgery is a feasible option for splenic resection in cases of spontaneous splenic rupture.
