Recurrent popliteal vein aneurysm.

A 28-year-old female presented with a soft mass in the left popliteal fossa. She had a popliteal vein aneurysm repair 4 years ago. Magnetic resonance venography and ultrasound revealed a recurrent saccular aneurysm on the site of the repair. It measured 3 x 4 cm and had no thrombus. The aneurysm was resected, and as the vein had adequate length, it was primarily repaired with an end-to-end anastomosis. She was placed on coumadin for 3 months. At follow-up, the vein was competent and free of thrombosis.
