Telangiectasia

Besides being hard to pronounce, Telangiectasia is the chronic dilation of groups of capillaries near the surface of the skin. It can develop anywhere on the body but is most common on the face around the nose, cheeks and chin. When similar veins are found on the legs they are commonly called spider veins. The causes of Telangiectasia can be congenital and acquired. Acquired causes include venous hypertension with underlying varicose veins. Blood flow abnormalities can also lead to Telangiectasia or spider veins in the legs. Telangiectasia usually isn’t painful, but the underlying causes may be.

There are two treatment options for Telangiectasia, laser treatments and foam sclerotherapy. Foam sclerotherapy is a non-operative treatment that uses micro-injection technology to inject a FDA approved solution called Sotradecol®. Compression stockings must be worn after sclerotherapy treatments on the legs.

The Reno Vein Clinic has experienced doctors who perform both treatment options for Telangiectasia. Call to set up a consultation today (775) 329-3100 or visit www.renoveinclinic.com for more information.

Types of Blood Vessels

Blood vessels are part of the circulatory system that transports blood throughout the body. There are three major types of blood vessels.

1. Arteries

Arteries carry blood away from the heart. Both arteries and veins have the same structure with three layers: tunica intima, tunica media, and tunica adventitia. The largest artery is the aorta, which carries blood out of the heart.

2. Capillaries

Capillaries enable the exchange of water and chemicals between the blood and tissues. Capillaries consist of a layer of endothelium and occasional connective tissue. Capillaries are the smallest blood vessels.

3. Veins

Veins carry blood from the capillaries back toward the heart. Veins are either arterial or venous, depending on whether the blood in it is flowing away from (arterial) or toward (venous) the heart. Most veins carry deoxygenated blood from the tissues back to the heart except for the pulmonary and umbilical veins. Veins are classified in a number of ways. Superficial veins are those that are close to the surface of the body and have no corresponding arteries. Deep veins are deeper in the body and have corresponding arteries. Pulmonary veins are a set of veins that deliver oxygenated blood from the lungs to the heart. Systemic veins drain the tissues of the body and deliver deoxygenated blood to the heart.
