Abdominal aortography is widely used for evaluation of potential renal donors and for patients with renal failure or hypertension in whom a renal artery ostial or polar branch stenosis is suspected. It would be desirable to use a catheter that consistently enables good bilateral renal artery and polar branch visualization without opacification of overlying mesenteric vessels. Existing and newly designed catheters were compared to determine the optimal design necessary for these studies. An in vitro model of the abdominal aorta and its branches was made, and dye dilution densitometry was employed for quantitative evaluation. Semiselective catheters demonstrated significantly increased renal artery opacification with decreased mesenteric opacification in this in vitro model.
腹主动脉造影广泛用于评估潜在的肾脏供体以及怀疑有肾动脉开口或肾极支狭窄的肾衰竭或高血压患者。理想的情况是使用一种导管，能始终如一地实现双侧肾动脉和肾极支的良好显影，而不会使覆盖其上的肠系膜血管显影。对现有的和新设计的导管进行了比较，以确定这些研究所需的最佳设计。制作了腹主动脉及其分支的体外模型，并采用染料稀释密度测定法进行定量评估。在这个体外模型中，半选择性导管显示肾动脉显影显著增加，而肠系膜显影减少。
