发帖数: 93 | 1 我的解剖很差，请教大家一个问题：主动脉狭窄（adult）引起的costal notching是因
为posterior intercostal arteries dilate. 但到底是因为直接扩张还是因为
internal thoracic arteries dilate从而引起的间接扩张？我觉得adult type of
aortic coarctation is proximal to the origin of posterior intercostal artery
, 所以在低压区，怎么会扩张呢？ | p********r

notching 讲的是另外一个问题，"侧枝循环" (collateral circulation). | b*********y
发帖数: 93 | 3 能讲得详细一点吗？是由antirior intercostal arteries来的侧枝吗？谢谢 | t*********m

collateral circulation, from the branches of the subclavian, the superior
intercostal, and the internal mammary arteries, bypassing the area of
coarctation.
