Es is caused by long-standing left-to-right shunt lesions, which induce pulmonary vascular changes, resulting in reversal of the shunt flow.
ES是由长期左向右分流引起，该左向右分流诱导了肺血管改变，导致分流方向逆转即右向左分流。
Objective To establish a rat model of pulmonary hypertension induced by left-to-right shunt and explore the influence of high pulmonary blood flow on pulmonary vascular collagen remodeling.
目的建立左向右分流所致肺动脉高压大鼠模型，了解高肺血流量对肺血管胶原代谢的影响。
These serve to shunt blood from the arterial to the venous side of the vascular system, thereby avoiding the capillaries, where exchange of oxygen and heat takes place.
血管球成为血流从动脉流至静脉的旁路，避免通过毛细血管产生氧气和热量交换。
