Purpose: To analyze the causes, clinical features, and computed tomography (CT) images of atypical varicose veins in the popliteal fossa unrelated to small saphenous vein (SSV) reflux by three-dimensional CT venography (3D-CTV).
Methods: A total of 1,476 limbs in 794 consecutive patients with varicose veins who underwent surgery from 2005 to 2009 were enrolled. The medical records, duplex ultrasound, and 3D-CTV images were analyzed retrospectively.
Results: Varicose veins in the popliteal fossa (PFV) were found in 438 of 1,476 limbs; the PFV in 428 limbs (97.5%) were caused by SSV insufficiency. Ten limbs (2.5%) had atypical PFV unrelated to the SSV. Incompetent perforator of the PPF was found in six of ten limbs (four women and two men; median age, 58-years). The CEAP clinical classes were C2 in four limbs and C4 in two limbs. The PPF drained to the popliteal vein in five limbs and to the gastrocnemial vein in one limb. A perforator ligation was performed in all patients, and additional sclerotherapy was performed in one patient. Thigh or calf perforator insufficiency was found in three limbs (two women and one man; median age, 62.7-years). The CEAP clinical classes were C2 in two limbs and C3 in one limb. Great saphenous vein insufficiency with Giacomini vein reflux was found in one limb (woman, 67-years).
Conclusion: An exact preoperative understanding of the anatomy and flow dynamics is essential for the proper treatment of rare atypical PFV. A preoperative evaluation with 3D-CTV can provide accurate anatomical information for the surgery.
