What complications are involved with Endovenous Laser Ablation?

If I have had large vessels such as the saphenous closed, is there chance of circulatory problems later on?

Endovenous laser ablation is minimally invasive and very safe. The worst complication would be a blood clot in the leg. This is very rare complication compared to any surgical procedure. In answer to your second question, if the larger saphenous vein is refluxing, or non functioning, the blood has already by- passed that vein. So when you close it off, it will actually make your leg health improve and help preserve the normal veins. The long term venous health will improve if the vein is ablated, but if untreated, will only become worse.
