Multiorgan Ultrasound for the Diagnosis of Submassive Pulmonary Embolism in a Critically Ill Patient.

Pulmonary embolism (PE) is a serious condition associated with significant morbidity and mortality. Multiorgan ultrasound offers a non-invasive, bedside alternative to computed tomography pulmonary angiography (CTPA) for rapid diagnosis and management, particularly in critically ill patients. We present the case of a 68-year-old woman with a high intermediate risk pulmonary embolism (PE), with Pulmonary Embolism Severity Index (PESI) class IV, multimodal ultrasound identified right ventricular dysfunction, elevated pulmonary artery pressures, and extensive lower extremity deep vein thrombosis, guiding timely diagnosis and management. This case highlights the utility of multimodal ultrasound as a non-invasive, bedside available diagnostic tool that facilitates effective management, particularly in critically ill patients when conventional imaging is not feasible.
