摘要
观察了60例狗心心房动脉,40例为冠状动脉铸型标本,20例为解剖标中,一般性心房动脉多为区域性小支,以1支多见,2支次之,但左、右心房外侧支以2支多见,甚至可多达4支。在特殊心房动脉中,窦房结动脉81.7%发自右冠状动脉;18.3%发自左冠状动脉。房室结动脉1支的占93.3%;2支的占6.7%,均发自左旋支。房间隔前动脉占21.7%;左房旋动脉仅占0.83%。此外,还观察了窦房结动脉与其他心房动脉的吻合。
he arteries belong to small rigional
branches,mostlysending one or two branches to atrium. The rightand
left lateral atrial atteries commonly have twobranches or even more
than four.81.7%of nutrient arteries to S-Anodes arise from the
rightcoronary artery,and 18.3%of them from the left one. In 93. 3%of
cases the A-V node re-ceives one nutrient artery and in 6.7%it
receives left circumferent atrial arteries. Anastomosisbetween the
nutrient arteries of S-A nodes and other atrial nutrient ateries are
also repoted.
