The purpose of the study was to examine the anatomical variations in the blood supply to the sinus node.
Gross anatomical examination and angiographic evaluation were performed in 400 human hearts derived from victims of various accidents.
The sinus node artery was a branch of the right coronary artery in 245 cases, the left circumflex in 147 cases, and both coronary arteries in 8 cases. In one subject, two sinus node arteries were found to arise from the left circumflex artery, a finding never reported before.
Anatomic and postmortem angiographic findings of a previously unreported case where the sinus node is perfused by two sinus node arteries originating from the left circumflex coronary artery are demonstrated. Knowledge of this anatomical variation is useful for anatomists and of clinical significance for the interventional cardiologists and mainly for the cardiac surgeons in planning the surgical procedures.
本研究的目的是检查窦房结血液供应的解剖变异情况。
对400例因各种事故死亡者的心脏进行大体解剖检查和血管造影评估。
245例中窦房结动脉为右冠状动脉分支，147例为左旋支动脉分支，8例为双侧冠状动脉分支。在1例受试者中，发现两条窦房结动脉发自左旋支动脉，此发现此前未见报道。
展示了1例此前未报道病例的解剖及尸检血管造影结果，该病例中窦房结由发自左旋冠状动脉的两条窦房结动脉供血。了解这种解剖变异对解剖学家有用，对介入心脏病学家具有临床意义，对心脏外科医生在规划手术操作时尤为重要。
