The risk of death after early conversion should be recognized, to avoid forcing morphological indications for primary EVAR. Occurrence of late conversion after EVAR is not negligible, affecting almost 1 out of 10 patients after 6 years. In the presence of an expanding aneurysm after EVAR, especially after a failed secondary endovascular correction, an aggressive attitude in fit patients allows outcomes at similar to those of primary OR.
We report a case of an arteriovenous fistula (AVF) following osteosynthetic treatment of a fracture of the lower limb 13 years ago. A stent-graft technique had been used to close a high flow traumatic AVF between the popliteal artery and the popliteal vein. The failure to properly evaluate traumatic AVF may sometimes lead to remarkable delay in diagnosis with devastating consequences including edema, ischaemia, ulceration and high output heart failure. Endovascular treatment of these lesions is promising but long-term follow-up will be required to determine the durable patency and the onset of potential complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
