The goal of this retrospective, single-center study is to analyze the impact of real-time ultrasound guidance on ventricular catheter positioning and early outcome of shunt survival.<\/jats:p><jats:p>We analyzed the charts and images of all patients who underwent shunt surgery from 09\/2017 to 12\/2022 and compared the position of the ventricular catheter using the freehand technique and real-time ultrasound guidance. Central catheter position was graded as grade I (optimal), II (contact with ventricle structures or contralateral), and III (misplacement).<\/jats:p><jats:p>A ventricular catheter was placed in 244 patients using real-time US guidance and in 506 patients using a freehand technique. The mean age (53.4 and 53.6 years, respectively) and the preoperative frontal occipital horn ratio (FOHR; 0.47 versus 0.44) were almost equal in both groups. In the study group, grade I catheter position was achieved in 64% of cases, grade II in 34%, and grade III in 2%. The control group showed grade I position in 45%, grade II in 32%, and grade III in 23% of cases (p&lt;0.05). An early central catheter failure rate was the highest in grade III (40.5%) compared to 4% in grade I.<\/jats:p><jats:p>Our data demonstrate that real-time US guidance leads to a significant improvement in ventricular catheter placement. Consequently, early shunt revisions decrease significantly. Further prospective, randomized, and controlled studies comparing the standard method to real-time ultrasound catheter placement are required.<\/jats:p>","DOI":"10.1055\/a-2352-9404","type":"journal-article","created":{"date-parts":[[2024,6,25]],"date-time":"2024-06-25T23:13:41Z","timestamp":1719357221000},"page":"170-176","source":"Crossref","is-referenced-by-count":1,"title":["The
