Chapter 12: Popliteal Artery Aneurysm

The following sections are included:

• Popliteal artery aneurysm (PAA) is the most common lower limb aneurysm.

• PPAs rarely occur in isolation.

• The majority present either as an incidental finding or as lower limb ischaemia.

• Aneurysm rupture is rare, but life and limb threatening when it occurs.

• All symptomatic PAAs should undergo repair.

• Asymptomatic PAAs >2 cm in maximum diameter should be considered for repair.

• Adequate imaging of the proximal and distal vasculature is vital for successful repair.

• Endovascular repair has promising results but the evidence base is still relatively weak.
