Anyone suffering from vascular diseases would need to see a vascular surgeon. Any diseases of the blood vessels like peripheral artery disease, renal artery disease, carotid artery disease, varicose veins, spider veins, May-Thurner syndrome, blood clots, aortic aneurysms and lymphedema can be treated by a vascular surgeon. In most of these cases, a patient may see a general physician or any other doctor and may be referred to a vascular surgeon.
