Venous aneurysms, particularly popliteal venous aneurysms, are a less common type of aneurysm. Due to their strong association with the development of deep venous thrombosis and recurrent pulmonary embolism, a comprehensive evaluation and intervention are necessary. The widespread use of venous duplex scanning has increased the identification of venous aneurysms, particularly in individuals with deep or superficial venous insufficiency. Optimal management involves surgical repair as a preventive measure, emphasizing the significance of early detection and intervention. The most commonly performed procedure is tangential aneurysmectomy with lateral venography. For patients with fusiform aneurysms or situations where tangential aneurysmectomy is impractical, aneurysm resection with preservation of venous continuity is recommended. Despite ongoing advancements, endovascular techniques lack a clearly defined role in their management, and open repair remains the established standard of care when necessary. The purpose of this article is to present a rare case of popliteal venous aneurysm that was observed in our outpatient department and to delineate the approach, we utilized in managing this condition.
