Summary
A persistent sciatic artery can serve as an access route for endovascular repair of infrarenal aortic aneurysms when femoral arteries are unsuitable. This case demonstrates successful treatment using this rare arterial variant.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Anatomical Variations
Background:
- Standard endovascular infrarenal aortic aneurysm repair utilizes femoral artery access.
- Persistent sciatic artery is a rare anomaly that can replace the femoral artery supply to the lower limb.
- An atrophic ipsilateral femoral artery can complicate standard surgical approaches.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
