THROMBOSED ANEURYSM OF THE SMALL SAPHENOUS VEINTHROMBOSED ANEURYSM OF THE SMALL SAPHENOUS VEIN

lntroduction : lsolated venous aneurysm is defineci as an focal vascular dilatation that  communicates with normal size venou s stru cture through a single channel, and it should not have  any association with an arteriovenous communication ora pseudoaneurysm. Venous aneurysms may rarely  bethrombosed. Here we present a female patientwith thrombosed venous aneurysm of the small  saphenous vein. Case Report: A 49 year-old woman was admitted to our hospital with complaints ofa growing mass at  the left popliteal region during the last 18 months. Physical examination revealed a firm  subcutaneous mass on the left popliteal region. Color tlow duplex imaging (CFDI) confirmed  thrombosed saccular venous aneurysm of the small saphenous vein extending to the saphenopopliteal  junction (SPJ) t h at measured approximately 3.2 cm in diameter. Surgical intervent ion was  performed under spinal anesthesia . The aneurismal mass was relatively thin walled and was occluded  by blood clot. Her postoperative course was uneventful and her symptoms resolved. Histologi c  findings were consistent withvenous aneurysm. Conclusion: in order to prevent the risk of deep venous thrombosis and even pulmonary embolism, we  think that thrombosed venous aneurysms close to the saphenopoplitealjunction should be operated  without delay.
