Introduction:
Persistent sciatic artery (PSA) is a rare embryological vascular anomaly with a prevalence between 0.025-0.06%. PSA is frequently associated with aneurysmal degeneration and can result in neuropathy, thrombosis, or rupture, threatening limb and life.
Case presentation:
We present a case of a 72-year-old man with an incidental finding of a right sided 4 cm PSA aneurysm with limited symptoms. The aneurysm was treated successfully with endovascular exclusion and a femoral-popliteal bypass was performed to revascularize the leg.
Discussion:
Treatment of PSA aneurysms involve excluding the aneurysm and revascularizing the involved leg. Improvements in endovascular embolization techniques now offer new solutions in the management of these aneurysms.
Conclusion:
A high degree of clinical suspicion is required to properly diagnose and treat PSA aneurysms. Referral to a center with expertise in both open and endovascular techniques is vital to ensure good outcomes.
