摘要: Abstract Objectives The purpose of this study is to determine the accuracy measuring pressure with a fluid filled device (needle) and non-fluid (catheter) inside thrombosed aneurysmal sac after exclusion from circulation by endovascular grafting. Methods In static environment, consisting syringe which monitoring kit was connected, experiments were performed influence type (either needle or catheter) effect characteristics medium on reproducibility measurements. pressures obtained in different kinds media compared those blood. Similar using catheter. Subsequently, measurements dynamic physiological environment. This environment consisted an artificial aneurysm, constructed porcine aorta human aortic thrombus, mounted. analyzed Bland–Altman plots. Results Under conditions, levels blood, starch solution thrombus similar. identical catheter significant lower than measured blood ( P Conclusion A device, inserted into like fibrin does not yield accurate reproducible results. tip-sensor rather superior aneurysm EVAR.
