Traumatic pseudoaneurysm(PA) most commonly with penetrating injury, Blunt mechanism is very rare and often delay diagnosis.We present one case of blunt injury induced brachial artery PA diagnosed by point of care ultrasound(US).
Patient and method
Brachial artery PA can be from 3 etiology:congenital, systemic disease, and trauma. Penetrating injury is most common mechanism.1 Clinical symptoms including redness, induration/ pulsatile mass and pain, Most case of brachial artery PA has delay presentation. In the literature review only 1 case was found for blunt traumatic mechanism not associated without humeral fracture,Inthese two cases were all diagnosed by US. Duplex US has good sensitivity and specificity in postcatheterizationpatients Typical US finding including cystic lesion adjacent to a supplying artery, ying-yang sign in cystic mass, to end fro sign. US also can be used in treatment, like ultrasound guide thrombin injection. Other diagnostic tools including CTA or angiography, but all have radiation.
Although PA of brachial artery in blunt trauma is rare disease, but should be considered in delay presentation after trauma. Point of care US can properly diagnose the PA in ED setting.
The study was conducted in accordance with the ethical standards dictated by applicable law. Informed consent was obtained from each owner to enrolment in the study and to the inclusion in this article of information that could potentially lead to their identification.
