Posttraumatic pseudoaneurysm of the posterior tibial artery – A case report

Arterial pseudoaneurysms as a result of blunt trauma are exceptionally rare, especially when developing in the posterior tibial artery. We describe a case of a 19-year-old patient with a pseudoaneurysm of the right posterior tibial artery following a blunt trauma with compression on the posterior tibial nerve leading to numbness in the sole of the foot. The pseudoaneurysm was successfully treated by open surgical repair with the use of an autologous venous patch from the greater saphenous vein. To the best of our knowledge, only one previous case of a posterior tibial artery pseudoaneurysm following blunt trauma has been described in previous literature. Our patient made an almost complete recovery, with only a persistent sensory deficit of the sole of the foot at three weeks postoperatively.
