Introduction: Subclavianarteryinjurysecondary to blunt trauma is rare. Most patients withblunt trauma that affects the major vessels die beforereaching the hospital due to trauma kinematics. Appropriate intervention requiresimmediate identification and propersurgicalapproach. The intraoperativediagnosisis more common due to the hemodynamicinstability of most patients; however, conventionalangiography and computedtomography (CT) angiography are alsouseful diagnostic modalities in stable patients to determine the location of the injuryprior to surgery. Wepresent a case of blunt trauma associatedwithsitusinversustotaliswhichis a rare congenital condition characterized by complete transposition of the thoracic and abdominal viscera.

Case Report: A 22-year-old man wasbrought to our trauma center, victim of motorcycle collision, with an occlusive bandage on the right neck/thoracicregion. Due to hemodynamicstability, CT scan conducteddirectly. The patient wastreatedwithsurgical exploration of the injurywith a supraclavicular incision, osteotomy of the middle third of the clavicle, proximal, and distal control of the subclavianartery. There was no evidence of brachial plexus injury. Small lacerationwasidentified in the right subclavianarterycaused by a bone fragment of the clavicle fracture. Weperformed a debridement of the subclavianinjury and primary suture withProlene 5-0.

Conclusion: Treatment of the subclavianartery trauma requiressolidanatomy for understanding the accuratelocalization of the arterialinjury, when possible, prior to surgery to ensure the approachwillbetarget effective with minimal time loss.
