我们介绍了在平淡的冠的 angiography 期间顺便说一下检测的异常单人赛冠的动脉的一个案例。与周期性的中略前和中略的六个事件介绍的一个 32 岁的男中国病人。双来源的计算断层摄影术(DSCT ) 执行的冠的 angiography 和冠计算断层摄影术(CT )-angiography 表明病人有一根单个大恰好冠的动脉。一个中等大的分支从单个恰好冠的动脉的近似部分发源并且延长了到左,过去对肺的动脉前面,并且在左耳的附器的底划分了成前面的下降动脉分支和降声调符号分支。中略的事件被怀疑被冠的动脉的痉挛引起,因此这个病人在 diltiazem 的 30 mg 的政体上是每 6 h 并且没在后续期间有中略的复发。
We presented a case of anomalous single-coronary artery detected incidentally during routine coronary angiography. A 32-year-old male Chinese patient presented with recurrent pre-syncope and six episodes of syncope. Coronary angiography and coronary-computed tomography (CT)-angiography performed by a dual-source computed tomography (DSCT) revealed that the patient had a single large right coronary artery. A moderately large branch originated from the proximal part of the single right coronary artery and extended to the left, passing the anterior to the pulmonary artery, and divided into the anterior descending artery branch and circumflex branch at the base of the left auricular appendage. The episodes of the syncope were suspected to be caused by coronary arterial spasm, so this patient was on a regimen of 30 mg of diltiazem every 6 h and had no recurrence of syncope during follow-up.
