供血动脉 meaning in Chinese
feeding artery
Examples
- The results showed that 8 cases of preoperative patients in gelfoams group had a good effect and bleeding were reduced during operation . one patient had vascular recanalization at 1 month after embolization with gelfoam . all patients in bletilla striatas had ideal effect
结果发现，明胶海绵组8例术前栓塞达到预期目的，术中分离容易，出血减少，有1例术后1个月血管再通， 3例效果好；白芨组均达到预期效果；弹簧钢圈组3例栓塞术后发现侧支供血动脉， 2例达到预期目的。 - 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
以水击原理分析了脑avm栓塞治疗时血液动力学变化过程，计算了瞬时水击压力可能达到的最高值。瞬时增高的水击压力可能是avm栓塞时发生急性脑出血或脑肿胀的重要血液动力学因素。而avm供血动脉血管壁面切应力偏高和供血动脉过长可增加水击的危险程度，提示对这类结构avm栓塞治疗时应采取合理的降压措施并尽可能分多次栓塞。
