case_images: Perioperative findings in a young man with PAES; (A) preoperative 3D contrast-enhanced CTA of left lower extremity; (B) preoperative enhanced MRI T1W imaging of left knee joint; (C,E) intraoperative exploration and left popliteal artery autologous saphenous vein bypass; (F) 3D contrast-enhanced CTA of left lower extremity at 3 months after operation. COPA, completely occluded popliteal artery; CTA, computed tomography angiography; FA, femoral artery; FB, fibrous band; GSV, great saphenous vein; L, left lower extremity; MRI, magnetic resonance imaging; OT, organic thrombus; PA, popliteal artery; PA-P1, the P1 segment of the popliteal artery; PA-P2, the P2 segment of the popliteal artery; PAES, popliteal artery entrapment syndrome; 3D, three-dimensional.

case_images: After admission to our hospital, lower limb computed tomography angiography (CTA) indicated thrombosis in the P2 segment of the left popliteal artery, with complete occlusion of the lumen (Figure 1A). Magnetic resonance imaging (MRI) of the left knee joint indicated the filling defect in the P2 segment of the left popliteal artery was considered to be possibly due to thrombosis, and the superficial surface of the P2 segment of the popliteal artery was suspected to be crossed by an abnormal ribbon of fibers (Figure 1B). Exploring the popliteal fossa confirmed that the strip-like ligament passed through the surface of the popliteal artery, and the affected popliteal artery showed a strip-like change without pulsation (Figure 1C). The fibrous strips on the surface of the popliteal artery were severed and loosened, and an organic thrombus was found within the popliteal artery (Figure 1D). The bypass popliteal artery was well filled and pulsated after surgery (Figure 1E). Moreover, the lower limb CTA showed that a patent great saphenous vein bypassed the left popliteal artery (Figure 1F).
