Abstract:
A persistent sciatic artery (PSA) is a rare congenital vascular anomaly, with an estimated prevalence ranging from 0.01% to 0.05%. This condition can cause ischemic events in the lower limbs and sciatic artery aneurysms but can also be asymptomatic. A PSA can complicate the treatment of other coexistent vascular diseases due to the thin caliber of the external iliac and femoral arteries. We report a case of a patient with bilateral PSAs and an infrarenal aortic aneurysm. The aneurysm was successfully treated by the endovascular approach. An ultra-low profile endograft associated with access incisions slightly above the usual position was used to overcome this challenging access.
