Defined as 15mm or more, the main concern is not rupture, but blood clots forming inside that can break off and cause severe limb ischaemia, potentially leading to limb loss in acute situations. Diagnosis typically uses a simple ultrasound. If one PAA is found, screening for PAAs in the other leg and for abdominal aortic aneurysms (AAAs) is strongly recommended due to common co-occurrence. For asymptomatic PAAs, intervention is generally recommended at 20mm to prevent clots. For high-risk patients, repair might be deferred until 30mm. Smaller PAAs (less than 20mm) may warrant repair if clots are present or blood flow is compromised. Acute limb ischaemia is an emergency: Mild to moderate cases may begin with clot-busting medication. Severe cases require immediate surgical or endovascular repair to save the limb. Repair methods include: *Open Repair:* Traditional bypass surgery using a vein, offering better long-term results but is more invasive. *Endovascular Repair:* Less invasive, uses a stent graft to line the artery from within, often preferred for high-risk patients. Regardless of treatment, regular follow-up with physical exams, pulse checks, and ultrasounds is vital to monitor the repair or the aneurysm itself.
