Endovascular treatment of traumatic carotid pseudoaneurysm with stenting and coil embolization.

Posttraumatic internal carotid pseudoaneurysm is an infrequent but potentially life-threatening condition that complicates approximately one-third of blunt carotid injuries. Other types of injuries include dissection, thrombosis, and complete disruption. Historically, carotid pseudoaneurysms have been managed operatively with repair, ligation, and anticoagulation, with percutaneous angioplasty and stenting emerging over the past decade. We present the case of a 19-year-old patient with a posttraumatic internal carotid pseudoaneurysm that increased in size with conservative management and was treated with coil embolization and stenting.
