To view blood flow through your heart, your doctor may inject a special dye into your coronary arteries. This is known as an angiogram. The dye is injected into the arteries of the heart through a long, thin, flexible tube (catheter) that is threaded through an artery, usually in the leg, to the arteries in the heart.
A wart is a small growth with a rough texture that can appear anywhere on the body. It can look like a solid blister or a small cauliflower. Warts are caused by viruses in the human papillomavirus (HPV) family. The appearance of a wart depends on its location on the body and the thickness of the skin. Palmar warts appear on the hand. Plantar warts affect the feet. As many as 1 in 3 children and teenagers are estimated to have warts, but only 3 to 5 percent of adults.
Common warts. Common warts are small, grainy skin growths that occur most often on your fingers or hands. Rough to the touch, common warts also often feature a pattern of tiny black dots â sometimes called seeds â which are small, clotted blood vessels. Common warts are caused by a virus and are transmitted by touch. Children and young adults are more likely to develop common warts, as are people who have weakened immune systems.
