ABSTRACT
Takaysu arteritis is a systemic disease characterized by stenosis or obstruction of aorta and its branches. Its etiology is unknown but clinical and serologic data suggest autoimmune process. Coronary artery involvement has been uncommon, but potentially fatal complication of Takayasu arteritis. A 41-year old female patients was presented with exertional dyspnea and anterioi chest pain of 2 week duration. Systolic bruit was heard at the both middle portion of internal carotid artery areas. Both radial arteries were palpated well but both femoral, popliteal and doralis pedis arteries were palpated weakly. Aortogram showed complete obstruction of descending thoracic aorta and collateral circulation of internal mammary artery. Coronary angiogram showed 80% stenosis at the middle portion of the right coronary artery. Calcium channel blocker and antiplatelet agent were prescribed. And her clinical symptom improved.
