If the saphenous vein is removed, how is the body able to circulate blood?

Small veins give deoxigenated blood to the main saphenous vein. After that, deoxygenated blood goes through the saphenous to the heart and lungs to get fresh oxygen and circulate it through arteries. If you remove the saphenous, how does this process work? How is the body able to circulate blood without it?

A healthy saphenous vein assists in returning blood from the lower extremities to the heart, but this function is dependent on the presence of a healthy system of check valves throughout the vein.

In the presence of venous insufficiency, where the valves are not working, blood runs in the wrong direction from the body down to the lower leg and actually overloads the other veins that are trying to return blood to the heart.

Under normal circumstances, 70-80% of the blood returning to the heart comes through the deep veins in the muscles of the leg.

In the circumstances of saphenous vein reflux or varicose veins, these deep veins have to work extra hard to return the blood to the heart.

After removal or ablation of a diseased saphenous vein, the blood will flow through the deep system in a normal manner. In most instances, the deep system has more than enough excess capacity to handle the blood that would normally go through the saphenous vein.

The saphenous vein is a superficial vein. There are many other veins in the leg that will carry the blood back to the heart. If someone has open heart surgery and the saphenous vein is removed for the bypass, that person still functions normally. The concepts are the same for saphenous vein ablation.

The same way the blood flows now with the refluxing saphenous vein. Your body uses the remaining miles and miles of collateral vein structure to circulate venous blood back up towards the heart. There is a lot of redundancy in one's vein structure.

The saphenous vein is not a major vein and, in fact, provides only a tiny amount of venous return. It is a superficial vein and all of the superficial veins in the lower leg only account for 10% of venous return.

I am noticing some blue reticular veins on my legs over the past couple years. They are beginning to seem more noticeable to me. They are light blue- not dark blue/purple. More recently, I have a few straight veins (not Ropey not twisted) that run diagonal on my legs that bulge slightly but only sometimes throughout the day... Every day, but not all day. I can't connect the bulging to any particular event. I workout daily and am of ideal weight. Does this signal varicose veins are coming?

I have varicose veins in my upper and lower legs. For this, I've been prescribed medical compression stockings that go up to the butt. They seem to be the best option, but they are not made for exercising. Now, what would be better and why: - Don't wear any compression wear while exercising - Wear sports compression socks (below knee level) - Wear sports compression tights (above ankle level)

I went to doctor last year and Doppler showed reflux in my left AAGSV. I wore compression hose but opted to wait to have EVLT. I went back to the doctor recently (a year later) and he did Doppler again. This time, however, no reflux was found. The only change has been a 20-30 lb weight loss. Is it possible for venous reflux to go away?
