Buerger’s disease restricts blood flow in the small and medium arteries. The exact cause is unclear, but tobacco use has strong links to the condition.
The condition mostly affects the limbs. A person’s symptoms vary depending on the location of the inflammation and the extent of the blood flow restriction.
This article examines Buerger’s disease, how doctors identify it by the signs and symptoms, and the risk factors that increase the likelihood of developing the condition.
We also look at the possible causes, potential complications, diagnosis, treatment, and the general outlook for people with Buerger’s disease.
In 1908, Leo Buerger first identified Thromboangiitis obliterans, now
It is a fairly rare condition that affects around
Buerger’s disease results in swelling in the small and medium arteries, mostly in the limbs. It often affects the legs more than the arms. The swelling
This disease causes pain in the areas it affects and can result in damage and death to the nearby body tissues.
Most signs and symptoms of Buerger’s disease result from the lack of oxygen to body tissues — when the blood vessels become inflamed, they block the blood from flowing freely.
The type and severity of symptoms depend on the location of the inflammation and the extent of the blood flow restriction.
- blue, red, or pale tinge to fingers or toes
- small, painful sores developing on the fingers or toes
- skin changes on the fingers or toes
- cold hands or feet
- burning or tingling pain in the hands or feet
- when walking, pain in the:
- feet, or foot arches
The main risk factor for Buerger’s disease is tobacco use. According to the
This is because tobacco contains chemicals that irritate the lining of the blood vessels, causing inflammation. The inflammation directly restricts blood flow by narrowing the vessels and can cause clots to form.
Other risk factors include age and sex. Buerger’s disease typically affects people
According to research from
Other conditions can cause inadequate oxygenated blood supply to the tissues in the arms and legs.
These conditions can
Scleroderma is an autoimmune disorder that damages the blood vessels and
The effects of scleroderma on the skin can cause contraction in the blood vessels in the extremities. This condition can cause Raynaud’s phenomenon, limiting blood supply to the fingers and toes.
Takayasu arteritis is another similar condition, as it
However, where Buerger’s disease affects the small and medium arteries, Takayasu arteritis typically damages the medium and large arteries and their branches, reducing blood flow around the body.
An important part of diagnosis is ruling out other possible causes of symptoms, so it is beneficial to consider related conditions.
When making a diagnosis, a doctor will consider the signs and symptoms of the condition and the history of tobacco use. They may then use a type of X-ray called an angiography to look at the blood vessels.
The results from a histology test provide the
There is no direct cure for Buerger’s disease, but
Other treatment strategies focus on managing symptoms, including:
- Prescription narcotics or nonsteroidal anti-inflammatory drugs (NSAIDs) can help to relieve pain.
- Vasodilators, such as calcium channel blockers, cause the blood vessels to widen, which allows more blood flow, resulting in lower blood pressure.
- Hyperbaric oxygen therapy improves symptoms in similar conditions such as diabetes. Research from
2018showed that combining this therapy with conventional treatment for people demonstrated some benefits to symptoms.
Another method is surgical revascularization to help restore blood flow. Where possible, doctors try to avoid amputation as an option.
The outlook is generally
A person should speak with a doctor to receive a diagnosis and treatment. Left untreated, it could result in complications.
While very rare, occasionally, death can result from Buerger’s disease. For example, the condition caused
People should speak with a doctor to discuss ways to quit smoking and prevent Buerger’s disease symptoms from progressing.
Buerger’s disease is a condition that is likely to result from chewing or smoking tobacco. Chemicals from tobacco cause inflammation in the lining of the small and medium arteries, causing them to restrict blood flow. This can also cause clots to develop, resulting in tissue death or damage in the limbs.
The restriction to oxygenated blood flowing can cause symptoms in the arms and legs, starting with coldness, pain, tingling sensations, and color change. In severe cases, the condition can lead to gangrene and infection.
There is no direct cure for Buerger’s disease. The main treatment is for a person to eliminate all forms of tobacco and nicotine from the system. In severe cases, doctors may consider surgical procedures.
