Acute Pulmonary Embolism from Subclavian Venous Thrombosis: CT Scan Diagnosis, Radiology Interpretation, and Emergency Imaging Insights
Introduction: A Silent Threat in Emergency Diagnosis A 42-year-old patient arrives at the emergency department with sudden dyspnea and mild chest discomfort. Vital signs are borderline unstable. Initial chest X-ray is unremarkable. However, within minutes, a CT pulmonary angiography (CTPA) reveals a life-threatening condition: acute pulmonary embolism (PE) originating from subclavian venous thrombosis . This scenario highlights the critical importance of CT scan diagnosis , radiology interpretation , and increasingly, medical imaging AI in modern trauma imaging and emergency diagnosis workflows. Pulmonary embolism remains one of the most underdiagnosed yet potentially fatal conditions in acute care medicine. When the embolic source is atypical—such as the upper extremity venous system (subclavian vein) —diagnostic complexity increases significantly. Pathophysiology of Acute Pulmonary Embolism Pulmonary embolism occurs when thrombotic material—typically originating fro...
