Superficial femoral vein banding or venous valve wall suture

By narrowing the width of the femoral vein, the relationship between the distal femoral vein width, the valve sinus and the valve length is restored, thereby correcting the valve insufficiency and preventing and reducing blood reflux. Treatment of diseases: primary lower extremity venous valve insufficiency Indication 1. No history of deep vein thrombosis. 2. After antegrade angiography, the deep vein is patency, enlargement, and straight tubular. Inverse angiography showed moderate or severe reflux. 3. During the operation, the femoral vein is thicker, but the contour, color and elasticity are normal, and there is no trace of inflammatory reaction. When testing the flow of blood, it can be seen that the proximal blood flows back across the valve to the distal side. Cut the wall of the tube and see that the free edge of the valve is slack and sagging. Surgical procedure 1. Reveal the total femoral, deep femoral, and superficial femoral veins as described above. The highest pair of valves in the superficial femoral vein were confirmed and the valve was insufficiency. 2. The superficial femoral vein was separated from the valve to the distal side by 2 to 3 cm long, and the superficial femoral vein after separation showed a persistent sputum state. 3. Take a large saphenous vein, cut open, take a vein piece about 0.5cm wide, wrap around the wall of the distal wall of the valve, suture 3 needles with the 0th line, complete the valve "band ring", use 5-0 without damage The line will fix the surrounding vein piece and the vein wall by 3 stitches to avoid sliding. 4. Or use 7-0 non-invasive line, suture at the distal end of the valve for a week, the needle spacing is about 2mm, can not penetrate the vein wall, so that the venous diameter after suturing is equivalent to the diameter of the venous vein (generally reduced by 1/3) ). 5. Strictly stop bleeding, rinse the wound, and suture the incision layer by layer.
