解釋
菌素類藥物-
The hemodynamic change induced by embolization of the cerebral arteriovenous malformation was analyzed using the water hammer principle. the highest pressure that can be reached when the water hammer phenomenon occurs was calculated. the acute instantaneous pressure rising may be an important factor leading to intracranial hemorrhage or swelling when the avm is embolized. it is shown that long feeding artery of avm will increase the possibility of direct water hammer, and high wall shear stress of feeding artery will increase the water hammer pressure. this suggests that such kind of avms should be embolized stepwise and the systemic pressure should be rationally reduced before embolization
以水擊原理分析了腦avm栓塞治療時血液動力學變化過程，計算了瞬時水擊壓力可能達到的最高值。瞬時增高的水擊壓力可能是avm栓塞時發生急性腦出血或腦腫脹的重要血液動力學因素。而avm供血動脈血管壁面切應力偏高和供血動脈過長可增加水擊的危險程度，提示對這類結構avm栓塞治療時應採取合理的降壓措施並盡可能分多次栓塞。
