Ultrasound Detection of a Pseudoaneurysm in the Internal Right Mammary Artery

In trauma management, continuous re-evaluation of patients is crucial over the ensuing hours and days. While computed tomography (CT) scans are typically recommended for serious cases and polytraumas, clinicians can also utilize ultrasound for subsequent evaluations. This report presents a clinical case where an ultrasound re-evaluation after an acute thoracic trauma event led to the identification of a rare complication: a pseudoaneurysm of the internal right mammary artery. Following the initial trauma, the patient underwent an ultrasound examination, which revealed findings indicative of this complication. Recognizing the importance of accurate diagnosis, the clinical team proceeded with an ultrasound-guided injection of thrombin to address the pseudoaneurysm. This minimally invasive procedure aimed to induce clot formation and effectively halt blood flow within the aneurysmal sac. Subsequent follow-up examinations confirmed the success of the intervention, as no arterial or venous blush was detected, indicating the absence of ongoing vascular compromise. This case highlights the value of ultrasound in the re-evaluation of trauma patients, particularly for diagnosing rare complications that may not be apparent through traditional imaging methods. Ultrasound serves as an essential tool in the trauma setting, enabling timely and accurate diagnoses that can significantly impact patient management and outcomes.
