# Traumatic pseudoaneurysm of the peroneal artery following lower extremity fracture – A case report and review of the literature

## TL;DR

A 17-year-old girl developed a rare peroneal artery pseudoaneurysm after a tibial and fibular fracture, which was successfully treated with coil embolization.

## Contribution

This case report highlights a rare complication of lower extremity fractures and its effective endovascular treatment.

## Key findings

- Traumatic pseudoaneurysm of the peroneal artery occurred after intramedullary nailing of a tibial and fibular fracture.
- Endovascular coil embolization successfully treated the pseudoaneurysm without major complications.
- The patient recovered fully and returned to semi-professional sports activities.

## Abstract

This report documents a rare case of arterial aneurysm following a closed midshaft tibial and fibular fracture. Briefly, a 17-year-old female suffered a traumatic lower extremity fracture and was treated by intramedullary nailing of the tibia. After an uneventful postoperative course, she noted a painful and pulsating swelling of the lateral aspect of the lower extremity about 2 weeks post op. Diagnostic ultrasound confirmed formation of traumatic pseudoaneurysm of the peroneal artery adjacent to the fibular fracture. Subsequent endovascular treatment using coil-embolization was successful. Bony healing occurred in a timely fashion and the patient returned to pain free semi-professional sports activities.
