Abstract

Vascular reconstruction with autologous vein grafts in musculoskeletal tumors poses biomechanical challenges.
A 35-year-old man developed pain and numbness during deep knee flexion 3.5 years after femoral artery reconstruction using the great saphenous vein.
Power Doppler ultrasonography revealed positional vascular compromise in the reconstructed graft.
Conservative management with activity modification.
Symptoms improved with avoidance of deep flexion; no further progression was noted.
Dynamic Doppler ultrasonography is a simple, noninvasive method for diagnosing mechanical graft compression after vascular reconstruction.
