Case ReportsSurgical repair of a post-traumatic arteriovenous fistula complicated by stent-graft misplacement.
An arteriovenous fistula (AVF) is an abnormal connection between an artery and a vein which may result from a traumatic injury or occur as a congenital abnormality. It may be asymptomatic or may present with a variety of symptoms. Surgical or endovascular treatment can be preferred. We present a case of unsuccessful percutaneous treatment of a femoral AVF due to misplacement of the stent-grafts, necessitating surgical correction.

Case ReportsAn arteriovenous fistula between the internal mammary artery and the pulmonary vein following blunt chest trauma.
A 67-year-old man suffered a traffic accident and was transferred to an emergency hospital close to the scene. He was diagnosed to have bilateral pneumohemothorax with a lung contusion, an anterior fracture dislocation of the C6-vertebra and a cervical cord injury at the level of C7. On the 48th day, massive hemoptysis was suddenly recognized. ⋯ On the next day, a selective left internal mammary arteriogram showed an arteriovenous fistula between the left internal mammary artery and the left pulmonary vein without any apparent extravasation. The arteriovenous fistula was successfully embolized using platinum fiber coils. The patient no longer demonstrated any hemoptysis after embolization.
