A forty-four-year-old woman with Takayasu's arteritis and involvement of the aortic arch and its main branches complained of precordial pain on effort. Exercise electrocardiograms revealed significant ST segment depression in leads II, III, aVF, and V. Coronary arteriograms demonstrated no stenosis. However, the right coronary arteriogram revealed collateral circulation arising from the sinus node artery to the bilateral vertebral arteries and the left internal carotid artery. The collateral circulation was considered to be an important route of blood flow supply to the brain and, at the same time, a cause of coronary steal syndrome and, consequently, of angina pectoris.
一名44岁患有高安动脉炎且主动脉弓及其主要分支受累的女性，主诉用力时心前区疼痛。运动心电图显示II、III、aVF和V导联ST段明显压低。冠状动脉造影未显示狭窄。然而，右冠状动脉造影显示有侧支循环，从窦房结动脉通向双侧椎动脉和左颈内动脉。这种侧支循环被认为是向大脑供血的重要血流途径，同时也是冠状动脉窃血综合征的病因，进而导致心绞痛。
