Anomalous origin of a septal perforator artery is an infrequent angiographic finding. However, its recognition is important in patients with coronary artery disease in order to avoid misdiagnosis and consequent management mistake. In 2 patients, coronary arteriography demonstrated an anomalous septal perforator artery supplying significant blood flow to a myocardial region previously perfused by a severely obstructed major coronary vessel. It appears that an anomalous septal artery can serve as an important source for supportive circulation in severe coronary artery disease.
间隔支动脉起源异常是一种少见的血管造影表现。然而，对于冠心病患者而言，识别该异常很重要，以避免误诊及随之而来的治疗失误。在2例患者中，冠状动脉造影显示一条异常的间隔支动脉为先前由严重阻塞的主要冠状动脉供血的心肌区域提供大量血流。似乎异常的间隔动脉可作为严重冠心病时支持性循环的重要来源。
