Thromboangiitis obliterans is a rare disease in which blood vessels of the hands and feet become blocked.
Thromboangiitis obliterans (Buerger disease) is caused by small blood vessels that become inflamed and swollen. The blood vessels then narrow or get blocked by blood clots (thrombosis). Blood vessels of the hands and feet are mostly affected. Arteries are more affected than veins. Average age when symptoms begin is around 35. Women and older adults are affected less often.
This condition mostly affects young men ages 20 to 45 who are heavy smokers or chew tobacco. Female smokers may also be affected. The condition affects more people in the Middle East, Asia, the Mediterranean, and Eastern Europe. Many people with this problem have poor dental health, most likely due to tobacco use.
Symptoms most often affect 2 or more limbs and may include:
There is no cure for thromboangiitis obliterans. The goal of treatment is to control symptoms and prevent the disease from getting worse.
Stopping tobacco use of any kind is key to controlling the disease. Smoking cessation treatments are strongly recommended. It is also important to avoid cold temperatures and other conditions that reduce blood flow in the hands and feet.
Applying warmth and doing gentle exercises can help increase circulation.
Aspirin and medicines that open the blood vessels (vasodilators) may help. In very bad cases, surgery to cut the nerves to the area (surgical sympathectomy) can help control pain. Rarely, bypass surgery is considered in certain people.
It may become necessary to amputate the fingers or toes if the area becomes very infected and tissue dies.
Symptoms of thromboangiitis obliterans may go away if the person stops tobacco use. People who continue to use tobacco may need repeated amputations.
Call your health care provider if:
People with a history of Raynaud phenomenon or blue, painful fingers or toes, especially with ulcers, should not use any form of tobacco.
