An Update on Acute Mesenteric Ischemia.

Can Assoc Radiol J 2022 05 11:8465371221094280. Epub 2022 May 11.

Department of Diagnostic Radiology, University of Manitoba, Winnipeg, MB, Canada

Acute mesenteric ischemia (AMI) is an uncommon yet highly lethal cause of acute abdomen in the emergency setting. Computed tomography (CT) imaging, in particular a biphasic protocol consisting of angiographic and venous phase scans, is widely used to corroborate non-specific clinical findings when suspicions of AMI are high. Techniques such as low kilovoltage peak scanning, dual energy acquisition, or a combined arterial/enteric phase can improve iodine conspicuity and evaluation of bowel enhancement. Read More

Pitfalls in medicine: pain out of proportion to examination findings.

Br J Hosp Med (Lond) 2022 Apr 6;83(4):1-8. Epub 2022 Apr 6.

Division of Emergency Medicine, Far East Rand Hospital, University of the Witwatersrand, South Africa.

Most life-threatening conditions form a coherent clinical picture, with examination findings confirming the patient's history. However, pain out of proportion to examination findings can also signify an emergency - acute compartment syndrome, bowel ischaemia, necrotising fasciitis and acute aortic dissection may all present in this way. A lack of situational awareness leads doctors to erroneously rely on examination findings to flag impending catastrophe, but in such cases misdiagnosis or delayed treatment can have dire consequences.

An Imaging Overview of COVID-19 ARDS in ICU Patients and Its Complications: A Pictorial Review.

Diagnostics (Basel) 2022 Mar 29;12(4). Epub 2022 Mar 29.

Department of Radiology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Via Albertoni 15, 40138 Bologna, Italy.

A significant proportion of patients with COVID-19 pneumonia could develop acute respiratory distress syndrome (ARDS), thus requiring mechanical ventilation, and resulting in a high rate of intensive care unit (ICU) admission. Several complications can arise during an ICU stay, from both COVID-19 infection and the respiratory supporting system, including barotraumas (pneumothorax and pneumomediastinum), superimposed pneumonia, coagulation disorders (pulmonary embolism, venous thromboembolism, hemorrhages and acute ischemic stroke), abdominal involvement (acute mesenteric ischemia, pancreatitis and acute kidney injury) and sarcopenia. Imaging plays a pivotal role in the detection and monitoring of ICU complications and is expanding even to prognosis prediction. Read More

Shifting surgical archetypes of ICG fluorescent-angiography for bowel perfusion assessment in cardiogenic shock under ECMO support.

J Card Surg 2022 Apr 21. Epub 2022 Apr 21.

General Surgery Department, Heart, Vascular and Thoracic Institute, Cleveland Clinic Florida, Weston, Florida, USA.

Extracorporeal membrane oxygenation (ECMO) has been adopted to support patients with acute severe cardiac or pulmonary failure that is potentially reversible and unresponsive to conventional management. Mesenteric ischemia (MI) can present as a life-threatening complication in patients receiving veno-arterial echocardiogram (ECHO) support. Due to the nature and acuity of these conditions, determining adequate perfusion upon surgical intervention is challenging for the operating surgeon, especially in cardiogenic shock (CS) patients on ECMO support persenting low arterial pulsatility.
