Coil embolization of an aberrant posterior tibial artery pseudoaneurysm after total knee arthroplasty

Endovascular treatment of a post-traumatic pseudoaneurysm arising from a ruptured posterior tibial artery with Menox. A case report

Posterior tibial artery pseudoaneurysms are rare and can occur in the setting of trauma. Endovascular treatment of post-traumatic pseudoaneurysms has become a viable less-invasive method particularly in young patients in whom the presence of collaterals guarantees distal vascularization. We report an unusual case of a 16-year- old patient who sustained blunt trauma to his right lower extremity due to a bicycle injury and developed a delayed symptomatic pseudoaneurysm of the posterior tibial artery in the absence of tibia fracture. Superselective endovascular treatment with Ethylene Vinyl Alcohol Copolymer based liquid embolic system (Menox) was successfully performed, achieving exclusion of the pseudoaneurysm with preservation of the remaining vascularization of the lower limb.
