Bilateral sciatic artery persistence in a patient with infrarenal abdominal aortic aneurysm

Persistent sciatic artery 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 it can also be asymptomatic. PSA may complicate the treatment of other coexistent vascular diseases due to the thin caliber of the external iliac and femoral arteries. This paper reports a case of a patient with bilateral persistent sciatic artery and 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 was used to overcome this challenging access.
