The blood supply in the skin is delivered by an interconnecting network of small arteries and veins. In the embryo, certain cells are responsible for stimulating blood vessel development. Simple tubelike blood vessels form first and then develop fully through the process of angiogenesis. The vasculature blood vessel network is the first organ to begin developing in embryo and continues until adulthood. Some blood vessel disorders are the result of the overproduction of blood vessel cells including angiomas (spider veins), varicose veins and telangectasias. Depending on the type and size of your blood vessels, treatments include laser therapy and injectable sclerotherapy. Drs. Martin and Cole Claiborne also treat infantile hemangiomas which are vascular malformations that occur during pregnancy and result in port-wine stains on the infant at birth.
