News - Automated CO 2 angiography: Injection pressure and volume settings


The purpose of this work was to outline some practical rules for pressure and volume settings in auto- matic CO 2 injection angiographic procedures focusing on the iliac arterial system, since, in current clinical practice, each  operator uses his personal experience to obtain imaging results which are not  always easy to compare. A theoretical model was thus developed and then  verified by a mechanical simulator of the aortoiliac vascular system, with  constant and pulsatile blood flow. The conditions of forward and reverse flows  have been described, both for constant and pulsatile regimens and pressures,  flows, and optical images of the bubbles in glass vessels were simultaneously acquired, analyzed and compared. Our results demonstrated that “good”radiological images (adequate to patient’s conditions and clinical need) are strictly related to appropriate settings of gas injection pressure and flow, in accordance with two simple operative rules. These rules prescribe that the patient’s pressure, the blood flow in the vessel, and the hy- draulic resistance of the gas injection line be known: the first two parameters may be estimated, while the third must be experimentally measured. By following these rules, it is possible to obtain the best results for each clinical setting, a more standardized approach and better imaging during angiographic procedures with carbon dioxide as contrast medium. ©2020 IPEM.
