Q：
How to define thromboangiitis obliterans?
A:
Thromboangiitis obliterans, also called Buerger disease, is a recurring progressive inflammation and thrombosis of small and medium arteries and veins of the hands and feet, which may be associated with use of tobacco products.
Common signs and symptoms of thromboangiitis obliterans include pain in affected areas, color changes in the extremities, range from cyanotic blue to reddish blue, reduced hair growth, ulcerations and gangrene in the extremities, etc.
Speaking of the treatments of thromboangiitis obliterans, in acute cases, drugs and procedures which cause vasodilation are effective in reducing pain; in chronic cases, lumbar sympathectomy may be occasionally helpful, because of its function of increasing blood flow to limb.
