Stent graft infixation after venous dislodgement in a patient with femoral posttraumatic arteriovenous fistula.

INTRODUCTION An arteriovenous fistula (AVF) is an abnormal connection between an artery and a vein which may result from traumatic injury or may occur as congenital abnormality. Stent graft repair through arteriovenous fistula could lead to complications. CASE REPORT Endovascular stent graft repair in a 23-year-old patient with posttraumatic superficial femoral arteriovenous fistula was performed to cover a fistula. During the procedure the device migrated through the fistula into the femoral vein. Due to eventual risk of migration to the heart, a prompt decision was made to fix the stent graft with three puncture needles in the common femoral vein region under fluoroscopy guidance. The vascular surgeon was called to perform open surgery. CONCLUSIONS The presented way of treating this rare complication in an extreme and uncommon situation is very efficient, safe and inexpensive.
