CT angiography showed a pseudoaneurysm of the inferior medial genicular artery which was treated at the same session by coil embolization.</p> <p><bold>Conclusions.</bold> A pseudoaneurysm of the inferior medial genicular artery can complicate primary total knee arthroplasty. An interventional radiologist assistance is necessary for diagnosis and management.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> Повреждения мелких сосудов при первичном тотальном эндопротезировании коленного сустава могут остаться незамеченными во время операции и проявиться в послеоперационном периоде.</p> <p><bold>Описание клинического случая.</bold> Пациентка 65 лет поступила в клинику через три недели после эндопротезирования коленного сустава с кровотечением в нижней части послеоперационной раны. КТ-ангиография показала ложную аневризму медиальной нижней коленной артерии, которая была устранена интервенционным рентгенологом при помощи спиральной эмболизации.</p> <p><bold>Заключение. </bold>Ложная аневризма медиальной нижней коленной артерии может осложнить первичное тотальное эндопротезирование коленного сустава.
