He was diagnosed with deep venous valve insufficiency of both lower extremities by ultrasound and antegrade venography in both lower extremities. He had performed valvuloplasty of the common femoral vein of both lower extremities. However, the symptoms gradually recurred 2 months after the operation, and the symptoms were the same as before the operation within half a year, and further aggravated. 

pysical examination：No special findings were found on the physical examination. There are surgical scars on the thighs of both lower limbs. No superficial varicose veins.
