Summary
Persistent sciatic artery (PSA) is a rare vascular anomaly with serious potential complications. This case highlights bilateral PSA discovered incidentally in a 77-year-old woman via CT angiography.
Area of Science:
- Vascular Surgery
- Radiology
- Anatomy
Background:
- Persistent sciatic artery (PSA) is a rare congenital vascular anomaly with an incidence of 0.04%-0.06%.
- PSA is associated with significant risks including thrombosis, thromboembolization, rupture, and aneurysm formation.
- Clinical presentation of PSA is highly variable, ranging from asymptomatic to severe limb ischemia.
Observation:
- A case of bilateral persistent sciatic artery was incidentally diagnosed in a 77-year-old female patient.
- The diagnosis was made during a computed tomography (CT) angiography of the lower limbs.
- This bilateral presentation is exceptionally rare.
Findings:
- The incidental finding of bilateral PSA underscores the importance of recognizing rare anatomical variations.
- Advanced imaging modalities like CT angiography are crucial for diagnosing such anomalies.
- Early diagnosis is vital for preventing potentially life-threatening complications.
Implications:
- Timely diagnosis of PSA can prevent severe complications such as limb ischemia or rupture.
- Awareness of PSA among clinicians is essential for appropriate patient management.
- This case contributes to the limited literature on bilateral persistent sciatic artery.

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

01:30Peripheral Artery Disease I: Introduction
152
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...
