Figure 5 A typical example of delayed repair of PAI at DGMV (60 h). A 41-year-old man was admitted to a local hospital due to a traffic accident, suffering tibia and fibula fractures with a popliteal artery injury of his left leg (A). At 2 days after trauma, the patient was transferred to our hospital. The skin color of the left foot seemed normal but there was no pulse (B). CTA revealed popliteal artery embolization at DGMV, but the blood signal of the gastrector artery, the calf artery, and the collateral circulation were very clear (C). The PAI was confirmed intra-operatively, and revascularization was performed by end-to-end anastomosis (D). After external fixation of the fracture, good knee function was presented (E, F). However, 1 year after fracture healing, poor ankle function (clubfoot deformity) was corrected by four-joint fusion (G, H).
