P15.08: Preliminary application of biplane mode using real time electronic 4D technology for fetal intervention

Abstract

Recently a newly developed real-time biplane mode using electronic 4D probe by GE Healthcare (Austria). This new probe realised real-time two-dimensional B-mode imaging (Biplane mode) and it also made possible to describe live needle tip moving. We applied this new technology into fetal intervention and analysed the feasibility and efficacy in some cases. We performed 8 cases of fetal intervention (2017.June-July) such as TTTS fetoscopic laser surgery, Radiofrequency ablation for TRAP sequence, fetal cord blood sampling, fetal blood transfusion, fetal ascites aspiration, thoraco-centesis for severe fetal pleural effusion, amnioinfusion and fetal intramuscular injection for anesthesia. We descriptively analysed the feasibility and efficacy of real-time two-dimensional B-mode bi-plane image using eM6C probe. In all cases, we found the safety because of the real-time two-dimensional images would provide other organ positions such as liver, lung, and heart that we could not see in using 1 dimensional image. In centesis into small cavity such as umbilical cord or thoracic cavity, 3D information supported us the successful centesis by leading tip position. The technical limit is that the well-trained assistant must chase the needle tip by tracking ball just online the guided needle after operator. We needed “momentary stop ” just before final insertion from the edge of the organ surface.
