本文对11例充分喝水后作动脉造影术的患者,研究含碘造影剂对其肾功能的影响.方法采用碘马尿酸盐(~(131)I hippurate)和~(99m)锝二乙烯三胺五醋酸(~(99m)Tc DTPA)连续作放射性核素肾图.研究选择性肾血流和肾总有效血流(ERPF)、肾小球滤过率(GFR)及滤过分数与造影剂用量、注射部位及原有肾病的关系.因为放射性核素法易于连续而准确地测定肾功能,故宜用来测定GFR和ERPF.11例非糖尿病患者,年龄为42～69岁(平均55.5岁).4例造影剂只注入腹主动脉,其中包括选择性地注入肾动脉.另4例造影剂限定注入心脏(3例)或髂动脉(1例),其余3例混合性地注入腹主动脉及髂动脉(2例)或腹主动脉及主动脉弓(2例).测定注入选择性部位的造影剂量,并以每公斤体重的有机结合碘毫克量来表示.所有病例在动脉造影前(1天9例,3天1例,4
In this paper, 11 cases of adequately drinking water for angiography in patients with iodine contrast agent on renal function.Methods Iodimarurate (~ (131) I hippurate) and ~ (99m) technetium divinyl ene (99m Tc DTPA) was used as a nephrogram to study the effects of selective renal blood flow, total renal effective blood flow (ERPF), glomerular filtration rate (GFR) and filtration fraction Contrast agent dosage, injection site and the relationship between the original kidney.Because the radionuclide method is easy and continuous determination of renal function, it should be used to determine GFR and ERPF.11 cases of non-diabetic patients, aged from 42 to 69 years (mean 55.5 years old.) Four contrast media were infused into the abdominal aorta, which included selective injection into the renal artery, another 4 into the heart (3 cases) or the iliac artery (1 case) Abdominal aorta and iliac artery (2 cases) or abdominal aorta and aortic arch (2 cases) .Conclusion The injection of selective sites of contrast dose, and the amount of organic compound per kilogram of body weight of iodine mg expressed in all cases before arteriography (1 day in 9 cases, 3 days in 1 case, 4
