ABSTRACT
CASE: An 18-year-old woman with Ehlers-Danlos syndrome developed subacute thigh pain on postoperative day 21 following elective hip arthroscopy and a periacetabular osteotomy. Doppler ultrasound revealed a pulsatile "yin-yang" lesion in the rectus femoris, and CT angiography confirmed a pseudoaneurysm of the lateral circumflex femoral artery with an arteriovenous fistula. Endovascular coil embolization with thrombin injection achieved complete thrombosis and symptom resolution.
CONCLUSION: Vascular injury, though rare, should be considered after hip arthroscopy in patients with connective tissue disorders. Early multimodal imaging enables timely diagnosis, and minimally invasive endovascular treatment can provide definitive management with low morbidity.
