Many patients have certain concerns with the closure procedure we may recommend for treating their venous insufficiency and varicose veins. The most common concern I hear is, “Is this a vein that I will need in the future for heart bypass surgery?” or “Don’t I have this vein for a reason and is it dangerous to close it?” Even many doctors do not fully understand this concept.
The saphenous vein that is responsible for most varicose veins is grossly abnormal, and this is the vein that is typically closed. It will never be suitable, and should not be used for heart or arterial bypass, if it requires closure. The incompetent vein is abnormal, weak, and dilates too easily when exposed to arterial pressure. A large dilated vein will clot and shut down within 3 to 6 months if it is used for bypass. As a vascular surgeon, I can tell you that I and my cardiology colleagues would never use this vein in the future, so there will be no use for it in other procedures that you may need. In addition, it is causing you the very symptoms that you are trying to alleviate.
Also, I have heard recently that patients believe that their legs will be a different size and not match once the vein is closed. SILLY! So the simple answer to your question is “No”. There is no future use for this incompetent saphenous vein. It can be safely closed as it has been for thousands of people as they seek a permanent solution to their varicose veins.
