Objective: Popliteal venous aneurysms are uncommon but potentially fatal abnormalities, since they can cause pulmonary emboli. Here, we report a case of a popliteal venous aneurysm of the right popliteal fossa. Method: In a 32-year-old healthy male complaining of a localised swelling and pain in his right popliteal fossa, duplex ultrasonography and angio-computed tomography revealed a giant popliteal vein aneurysm. The popliteal fossa was surgically explored and aneurysm was resected partially and sutured through posterior approach. Results: Recovery was uneventful and patient still remains asymptomatic. Further duplex ultrasonography follow-ups revealed patency of popliteal vein without thrombotic changes in 1st, 6th, 12th and 15th months. Additionally, no dilatation of the operated vein segment has been observed in the follow-up ultrasound studies. Conclusion: Surgical repair of popliteal venous aneurysms can be performed safely. Partial aneurysm resection together with lateral venorrhaphy is preferred. Due to pulmonary thrombo-embolic complication risks, we recommend surgery in early stages.
