A closed gas pressure pistol was used in 50 patient CO2 angiography as a supplementary method to conventional injection with liquid contrast medium. These were diagnostic pelvis-leg angiographies (n = 36), therapeutic angiographies (n = 8), haemodialysis fistulas (n = 3), suspected stenosis of a renal transplant artery (n = 1) and suspected renal artery stenosis (n = 1). 246 renal angiography series were performed with CO2. Dosages varied in accordance with the imaged vascular area between 10 ccm;(shunt imaging) and up to 100 cm3 (pelvis-leg angiography), at pressures between 400 mbar in case of haemodialysis fistulas up to 2000 mbar in the pelvis-leg area. Short-term feeling of fullness and even nausea were accompanying symptoms in 4 patients. The image quality was slightly inferior to that of conventional contrast medium images due to an elevated signal-to-noise ratio. Injector-monitored CO2 angiographies enabled imaging of the distal aorta or of peripheral vascular sections, imaging of the upper extremity and presentation of kidney transplants in patients with a relative or absolute contraindication to iodised contrast media.
在50例患者的二氧化碳血管造影中，使用了一种封闭式气体压力手枪作为传统液体造影剂注射的辅助方法。这些包括诊断性骨盆 - 腿部血管造影（n = 36）、治疗性血管造影（n = 8）、血液透析瘘管造影（n = 3）、疑似肾移植动脉狭窄造影（n = 1）和疑似肾动脉狭窄造影（n = 1）。共进行了246次二氧化碳肾血管造影系列检查。剂量根据成像血管区域而有所不同，在分流成像时为10立方厘米，在骨盆 - 腿部血管造影时高达100立方厘米，压力在血液透析瘘管造影时为400毫巴，在骨盆 - 腿部区域高达2000毫巴。4例患者出现短期饱腹感甚至恶心等伴随症状。由于信噪比升高，图像质量略逊于传统造影剂图像。注射监测的二氧化碳血管造影能够对远端主动脉或外周血管段进行成像、对上肢进行成像，并能在对碘化造影剂有相对或绝对禁忌证的患者中呈现肾移植情况。
