Venous Bypass Surgery
For more extensive problems, your surgeon may recommend bypass surgery to treat CVI that occurs in the upper thigh or pelvis. For example, your surgeon can connect an artificial vein, called a graft, or a transplanted vein to a vein not affected by CVI to help blood flow from your affected leg around the blocked vein. Most vein surgery can be performed through small incisions. Usually bypass surgery is safe, although there is a small risk of DVT and infection at incision points. Your physician will only recommend this procedure in the most serious instances.
