Objective:
To evaluate the therapeutic effects of external valvuloplasty technique in deep venous valve insufficiency of the lower limbs.
Methods:
External valvuloplasty of the femoral vein valve was performed in 30 patients(41 limbs) with deep venous valve insufficiency of the lower limbs. The patients ranged in age from 16 to 69 years (mean +/- s, 50.8 +/- 9.2). External valvuloplasty of the first pair of superficial femoral vein valve was carried out in all limbs. External valvuloplasty of the second pair of superficial femoral vein valve was added in 7 limbs and valvuloplasty of the common femoral vein valve in 6 limbs.
Results:
Venous claudication, swelling, aching disappeared in 78.0% limbs (32), obvious improvement was seen in 22.0% (9), and varicosis disappeared in all limbs. Ulcer healing was observed in 80% (8/10) limbs. Deep venous valve sufficiency was shown in 90.2% limbs, and reflux I degree-II degree in 4 by color Doppler.
Conclusion:
External valvuloplasty is an effective method to treat deep venous valve insufficiency of the lower limbs.

Veins of Lower Limbs
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the knee,...

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
