Introduction: Arterial pseudoaneurysm is a hematoma that is formed after damage to the arterial wall. We report a rare case of peroneal artery pseudoaneurysm after open reduction and internal fixation with interlocking nailing and partial fibulectomy for non-union for the right tibia in a 31-year-old male. The patient presented with a bleeding sinus over the leg swelling, and it was managed with an exploration of the pseudoaneurysm and ligation of the peroneal artery.
Case report: A 30-year-old male patient presented with a non-union tibia on the right side and had undergone plating of the tibia at another institute for a fracture of both bone legs approximately 18 months ago. The revision surgery was performed in which a previously inserted implant was removed and an interlocking nail was inserted, along with a partial fibulectomy. The post-operative period was uneventful. At 8 weeks after the second surgery, the patient came with a complaint of swelling at the outer aspect of the right leg. Computed tomography and angiography confirmed a peroneal artery pseudoaneurysm of 3.2 × 2.8 × 3.8 cm. Pseudoaneurysm was explored, and the artery was overrun with a Figure-8 stitches using a monofilamentous, and non-absorbable suture.
Conclusion: This case report highlights the occurrence of pseudoaneurysm after an orthoapedic procedure such as a partial fibulectomy. A high level of clinical suspicion, proper imaging, and early endovascular or surgical intervention is recommended to prevent complications.
