    A patient presented with a ruptured sciatic artery aneurysm and significantly enlarged persistent sciatic arteries. This rare condition involved a 10 cm dilated left artery and slow flow in tortuous iliac and sciatic vessels.

    Area of Science:

    • Vascular Surgery
    • Radiology
    • Medical Imaging

    Background:

    • Persistent sciatic artery is a rare congenital anomaly where the sciatic artery fails to regress during embryonic development.
    • Aneurysmal dilation of these arteries can lead to serious complications, including rupture.

    Observation:

    • A case study detailing angiographic findings in a patient with enlarged persistent sciatic arteries.
    • The left persistent sciatic artery was patent, dilated to 10 cm, and ruptured in the lower thigh.
    • Associated findings included dilation and tortuosity of the common iliac, internal iliac, and bilateral sciatic arteries, with patchy calcification and extremely slow arterial flow.

    Findings:

    • Confirmation of a ruptured sciatic artery aneurysm.
    • Significant ectasia and tortuosity of the entire sciatic artery and its proximal supply.

  • Demonstration of markedly reduced arterial flow necessitating delayed imaging.

    • Implications:

    • Highlights the critical importance of recognizing and diagnosing persistent sciatic artery anomalies.
    • Emphasizes the risk of rupture and the need for timely intervention in affected individuals.
    • Provides valuable insights into the complex vascular anatomy and flow dynamics in such cases.
