Symptoms of CVM

When located in an extremity, CVMs may show us as a birthmark, a visible or palpable mass of blood vessels, or may stimulate the development of collateral blood vessels in the form of varicose veins, or produce an enlargement of the limb or a lengthening of the limb by stimulating its bony growth centers. The localized masses may be of various sized from small to huge and at their surface the vessels may be vulnerable to injury and bleed or may even break down and ulcerate. AVFs, by “stealing” blood from the circulation beyond them may cause “ischemic” pain, which is the medical term for pain that results when circulation is so restricted that the tissues, and the nerves serving them, do not get enough blood.
