Abstract

Background: It is very important to determine the surgical anatomy of the aortic root when performing spreading aortic root preserving heart surgery. This study focuses on the surgical aspect of the aortic root anatomy by performing dissection of Korean cadavers. Material and Method: The subjects were 62 cadavers. We measured the intercommissural distances, heights of the sinuses and the circumference of the sinotubular junction and the aortic annulus. Result: The mean age of death was 61.3 years. The intercommissural distance for the right coronary sinus was $0.73{\pm}2.23mm$, that for the non coronary sinus was $19.34{\pm}2.03mm$, and that for the left coronary sinus was $18.58{\pm}2.15mm$. The height of sinus was $20.59{\pm}2.48mm$ for the right coronary sinus, $18.61{\pm}2.26mm$ for the non coronary sinus and $17.95{\pm}19mm$ for the left coronary sinus. The circumference of the sinotubular junction was $70.73{\pm}5.94mm$ and that of the aortic annulus was $77.94{\pm}5.63mm$. There is no correlation between age and STJ, aortic annulus and the ratio of STJ of aortic annulus respectively (p=0.920, p=0.111, p=0.073). The tilting angle of the sinotubular junction and aortic annulus is from $2.03^{\circ}$ to $7.77^{\circ}$ $(mean=4.90^{\circ})$. Conclusion: The intercommissural distance and the height of the sinus were largest in the right coronary sinus, and the position of the sinotubular junction to the aortic annulus is obliquely tilted levo-posteriorly.

배경: 대동맥 근부를 보존하는 심장수술이 점차 늘어남에 따라 대동맥 근부의 해부학적 구조에 대한 중요성 또한 증가하고 있다. 본 연구는 외과적 관점에서 필요한 대동맥 근부를 한국인 해부학 실습용 시신에서 실측하여 대동맥 근부의 진단 및 수술적 처치의 기준으로 하고자 한다. 대상 및 방법: 사인이 심혈관 질환이 아닌 시신 62구 중 대동맥 판막이 쌍엽인 1구, 기술적 오류로 대동맥 근부가 손상된 4구, 고정기간 중 변형이 심한 10구를 제외한 47예를 대상으로 하였다. 각 교련사이 간격, 대동맥 동의 높이, Sinotubular junction 및 aortic annulus의 길이를 측정하여 비교하였다. 결과: 시신의 사망 나이는 평균 61.3이었으며 남성이 31, 여성이 16구였다. 각 교련사이 간격은 Right coronary sinus $20.73{\pm}2.23mm$, Non coronary sinus $19.34{\pm}2.08mm$, Left coronary sinus $18.58{\pm}2.15mm$였다. 각 대동맥동의 높이는 Right coronary sinus $20.59{\pm}2.48$, Non coronary sinus $18.61{\pm}2.26mm$, Left coronary sinus $17.95{\pm}19mm$였으며, 통계 분석에서 교련사이에 길이 및 대동맥동의 높이는 Right coronary sinus가 가장 컸으며, Non coronary sinus, Left coronary sinus 순으로 나타났다. Sinotubular junction의 길이는 $70.73{\pm}5.94mm$, aortic annulus는 $77.94{\pm}5.63mm$였으며 Sinotubular junction의 길이, 대동맥 판륜의 길이와 대동맥 판륜에 대한 Sinotubular junction의 길이의 비를 각각 나이와 비교 분석했을 때 상관관계가 없었다(p=0.920, p=0.111, p=0.073). 대동맥 판륜과 sinotubular junction의 기울기는 $2.03^{\circ}$에서 $7.77^{\circ}$ (평균$=4.90^{\circ}$)였다. 결론: 각 교련 사이 간격 및 대동맥동의 높이는 non-parametric ANOVA test 결과 Right coronary sinus, Non coronary sinus, Left coronary sinus의 순으로 유의한 크기차이를 보였다(p=0.00). Sinotubular junction의 둘레 길이는 대동맥 판륜의 길이보다 9.3% 작았고 sinotubular junction이 aortic annulus에 대해 좌후측으로 기울어져 있었다.
