Abstract

Vascular complications of distal femoral fractures are rare but can have disastrous consequences if not recognised and treated promptly. We present the case of a 55-year-old woman who developed a pseudoaneurysm of the superficial femoral artery after osteosynthesis to repair a supracondylar femoral fracture. Eight weeks after surgery, swelling of the right thigh persisted and was accompanied by severe pain. Enhanced computed tomography revealed a pseudoaneurysm in the medial aspect of the affected thigh. Open surgical repair was performed by direct arterial suture. Although the true aetiology of the development of the pseudoaneurysm is unknown, a bony fragment from the reduction manoeuvre may have damaged the adventitia of the superficial femoral artery. In cases of continuous thigh swelling after osteosynthesis to repair a supracondylar femoral fracture, a diagnosis of pseudoaneurysm should be considered and treatment should be initiated immediately.
