摘要
目的探索能最佳显示右房室瓣环的造影投照体位。方法选用健康山羊8只,行右心房造影。使用对比剂总量110ml,注射速度12ml/s,压力800psi,右前斜(RAO)90°至左前斜(LAO)90°的180°旋转连续造影。结果8只山羊均成功行右心房造影,每只羊获得右心房连续造影图像各100帧,通过逐帧分析,发现右房室瓣环在右前斜27°±3°投照体位所获得的图像最佳,并能较准确的测量右房室瓣环直径的大小。结论右房室瓣环造影以右前斜27°±3°投照体位为佳。
Objective To explore the optimal project position for demonstrating tricuspid annulus angiographically in experimental goats. Methods Eight healthy goats underwent fight atrial angiography by using 6 F pig tail catheters. Under fluoroscopic monitoring the contrast media （total 110 ml, flow rate 12 ml/ s, pressure 800 psi） was injected continuously while a serious exposures were performed from RAO position to LAO position （totally 180° rotation）. The maximum diameter of the tricuspid annulus in every picture was measured and the results were compared with that obtained from sonography. Results The procedure was successful in all 8 experimental goats. The optimal project position to display the tricuspid annulus was at 27°±3° in RAO position. Conclusion In angiography, the tricuspid annulus can be best demonstrated at the project position of 27° ± 3° in RAO. （J Intervent Radio/, 2009, 18： 144-146）
