Optimization For The Injection Of Lipiodol Emulsion Via Microcatheter During Transcatheter Hepatic Arterial Chemoembolization

ObjectiveTo investigate the method to optimize the injection of lipiodol emulsion by microcatheter during transcatheter hepatic arterial chemoembolization.MethodsWe used three types of microcatheter to inject same solvent-lipiodol emulsion. The pressure of the catheter tips and the amount of injected lipiodol emulsion of each type of microcatheter were detected by a self-developed in vitro device for the same duration during the injection. Then these parameters were measured by using three types of solvent-lipiodol emulsion, respectively, in the same type of microcatheter and under same conditions. Data were compared among groups accordingly.ResultsThe pressure of the catheter tips and the amount of injected lipiodol emulsion by using the Stride microcatheter are largest, followed by the Progreat microcatheter,with the Echelon microcatheter coming in least (P<0.01). The pressure of the catheter tips and the amount of injected lipiodol emulsion of three types of solvent-lipiodol using the same type of microcatheter are different (P<0.01). The aforementioned parameters of the ioversol-lipiodol emulsion are least (P<0.01)while there is no significant difference between the lidocaine-lipiodol emulsion and NS-lipiodol emulsion (P>0.05).ConclusionsSelecting the Stride catheter and lidocaine-lipiodol emulsion can optimize the lipiodol emulsion injection and minimize the duration of X-ray exposure during monitoring the injection of lipiodol emulsion and consequently reduce the total radiation exposure to medical personnel and patients.
