Endovascular treatment of delayed presentation post-traumatic anterior tibial artery pseudoaneurysm in pediatric patient.

Post-traumatic pseudoaneurysms are rare complications of lower extremity fractures, especially in children, and may arise after high-energy trauma. This case report details a 13-year-old boy who developed a delayed anterior tibial artery pseudoaneurysm after surgical fixation of a tibia and fibula fracture. Despite initial recovery, he presented with a recurrent pulsatile ankle mass. Imaging confirmed a pseudoaneurysm, and endovascular coil embolization was chosen to avoid disrupting surgical hardware. The procedure resolved symptoms and halted blood flow into the lesion. This case highlights the importance of considering vascular injuries in persistent symptoms and supports minimally invasive endovascular techniques in pediatric trauma care.
