Atherosclerotic plaques tend to involve arterial localizations in which blood flow is not laminar due to arterial bends and bifurcations. A 49-year-old man was admitted to hospital with breathlessness and was subsequently diagnosed with left ventricular failure. Coronary angiography revealed three-vessel coronary artery disease and an anomalous extra left anterior descending artery taking off from the right sinus of Valsalva and spared from atherosclerosis. The absence of side branches and the relative lack of bends in arterial geometry were considered to be the cause of resistance to atherosclerosis. The present case identifies local flow conditions as an important factor determining the genesis of atherosclerosis in arterial segments.
动脉粥样硬化斑块往往累及动脉局部,在这些部位,由于动脉弯曲和分支,血流并非层流。一名49岁男性因呼吸困难入院,随后被诊断为左心室衰竭。冠状动脉造影显示三支血管冠状动脉疾病以及一条异常的额外左前降支动脉,该动脉从瓦尔萨尔瓦窦右侧发出,未发生动脉粥样硬化。侧支血管的缺失以及动脉几何形状中相对较少的弯曲被认为是抵抗动脉粥样硬化的原因。本病例表明局部血流状况是决定动脉节段动脉粥样硬化发生的一个重要因素。
