The persistent sciatic artery is a rare anatomical variant, representing the persistence of the sciatic artery in adult life that is responsible for the major blood supply to the lower limb in early embryologic development. Such persistence may be bilateral and can remain asymptomatic for many years. However, aneurysmal degeneration has been described as a complication of the persistent sciatic artery, which may cause critical limb ischemia resulting from thrombosis or embolization of aneurysm thrombus. Digital subtraction angiography, Doppler ultrasound, computed tomography angiography and magnetic resonance angiography are the most frequently used diagnostic tools to detect, classify and determine the presence of complications of a PSA. Early detection of this vascular abnormality on imaging studies can avoid life-threatening complications. We describe 4 patients with PSA that were diagnosed as an incidental finding in magnetic resonance imaging of the hip and demonstrate its characteristic imaging appearance.

“…9 The presentation is variable: a buttock mass (occasionally pulsatile) can cause sciatic nerve compression and radicular pain 10 ; thrombosis can occur within the aneurysm as a result of turbulent flow, causing acute, subacute, or chronic distal extremity ischemia 7 ; or distal embolization, 3 as in this patient, can also occur, but rupture of a PSA aneurysm is rare. 4 Occasionally, an asymptomatic PSA may be discovered incidentally during hip prosthesis insertion 11 or when the internal iliac artery is used as a recipient vessel during renal transplant. 12 DSA has been the mainstay of diagnostic imaging, but it is an invasive procedure that may fail to delineate runoff adequately, even with large volumes of contrast media owing to slow flow within the PSA.…”

Surveillance and Conservative Management of a Persistent Sciatic Artery Aneurysm

A persistent sciatic artery aneurysm is a rare congenital vascular anomaly. Surgical intervention is reserved for symptomatic cases. The authors report the case of a 72-year-old woman who presented with thromboembolic occlusion of an aneurysmal persistent sciatic artery. Although initially symptomatic, she was managed expectantly with the aid of serial duplex sonographic imaging. The persistent sciatic artery subsequently thrombosed as a result of hypotension secondary to a myocardial infarction. No surgical intervention was required. The current literature on this condition is reviewed.
