Abstract

Blunt subclavian artery injuries are rare and are associated with high morbidity and mortality. Several case reports have suggested that endovascular repair is safe with short operative times and minimal blood loss. We report a case of a 20-year-old male patient involved in a high-speed motor vehicle collision that resulted in partial transection of left subclavian artery with complete luminal thrombosis. Patient also had a left main-stem bronchus avulsion along with major intra-abdominal injuries and multiple spine and long bone fractures. He underwent emergent abdominal exploration due to multisystem trauma and hemodynamic instability. Following laparotomy and resuscitation, the subclavian artery injury was repaired using a hybrid technique geared at protecting the patent vertebral and axillary arteries from embolization. We used supraclavicular dissection and arterial control with endovascular stent-graft placement in retrograde fashion to repair the left subclavian artery injury. At 6-month follow-up, computed tomography scan confirmed patency of the left subclavian artery stent and there was no evidence of vertebrobasilar insufficiency or left upper extremity ischemia. In conclusion, stent-graft repair of blunt subclavian artery injuries is expedient and safe. Supraclavicular vascular dissection and control are effective in preventing distal embolization in rare cases complicated with luminal thrombosis.
