“If you ablate one vein will it cause reflux to occur in another?”

No, although many patients may have multiple areas of venous reflux involving multiple viens, once a single vein is treated the efficacy of that treatment is over 95%. In other words, once a vein is ablated, that vein will stay closed permanently. Ablation is a very durable solution. Other veins, may, however require additional treatments including ablation or other therapeutic modalities such as sclerotherapy or phlebectomy depending on the size and location of the offending veins.
