Pseudoanévrisme secondaire hémorragique de l'artère géniculée supéromédiale après épiphysiodèse fémorale distale

A 16-year-old male developed a false aneurysm of the superomedial genicular artery five weeks after medial distal femoral epiphysiodesis. The aneurysm was revealed by inexhaustible bleeding from the medial aspect of the knee and the presence of acute hemorrhage which resolved spontaneously. Physical examination disclosed disunion of the surgical wound at the apex of a pulsatory tumefaction over the medial aspect of the knee. AngioCT enabled the diagnosis of a false aneurysm of the superomedial genicular artery. Emergency surgery was undertaken to drain the hematoma and exclude the false aneurysm by ligating the superomedial genicular artery.
