Abstract: Objective To explore the application of computed tomography venography(CTV)in the diagnosis and treatment of recurrent lower extremity varicose veins. Methods The clinical data of 91 patients(91 limbs)with recurrent lower extremity varicose veins treated in our hospital during Jan. 2014 and Dec. 2019 were analyzed. The CTV data were collected and three-dimensional models were reconstructed. The causes of recurrence were analyzed with reference to the cross-sectional images and three-dimensional models, and the culprit veins causing recurrence were accurately located by previewing visualized surgeries. Individualized treatment plans were developed with the help of color Doppler ultrasound. The application value of CTV in the diagnosis and treatment of recurrent lower extremity varicose veins was evaluated based on curative effects and follow-up results. Results The cross-sectional images and three-dimensional models of CTV could identify the cause of recurrence and clearly display the culprit veins and adjacent tissues. After individualized surgeries, the varicose veins disappeared and ulcers healed in 21(13.5-31.0)days. During the follow-up of 5 to 60［average 18(11-27)］ months, no varicose veins or ulcers recurred. The diameter of the iliac vein and number of valves measured by CTV were significantly smaller than those measured by color Doppler ultrasound(P<0.001), but the number of perforating veins was significantly larger(P<0.001). Conclusion CTV can help to clearly determine the cause of recurrence of varicose veins in lower extremities, accurately locate the culprit veins, and provide intraoperative road map information. It has clinical value that color Doppler cannot replace.
