Magnetic resonance imaging (MRI) revealed the presence of a popliteal mass with a cephalocaudal diameter of 11 cm (Figure 1). Computed tomography angiogram (CTA) depicted a multilobulated mass (5.6 x 5.6 x 14.3 cm) extending from the midthigh to popliteal fossa, with the presence of thrombus inside (Figure 1).
(a) Giant popliteal artery aneurysm intraoperatively. (b) Revascularization with polytetrafluoroethylene (PTFE) graft.

With medial approach, the distal superficial femoral artery and the distal popliteal artery were exposed to allow proximal and distal arterial control (Figure 2). A bypass grafting was performed from the distal femoral artery to the distal popliteal artery above the knee with the use of a polytetrafluoroethylene (PTFE) graft in an end-to-side fashion (Figure 2).
