a Absent and pinpoint IJV flow was considered abnormal on TOF and TRICKS; the presence of at least 1 of the following IJV parameters was considered abnormal on a DS examination: B-mode abnormalities (flaps, septa, web), stenoses, absence of detectable flow, and presence of reflux in both sitting and supine positions. On CV, the presence of stenosis >50% of the IJV diameter or at least 1 of the following anomalies was considered abnormal: annulus, septum/valve malformation, hypoplasia, twisting, membrane, and agenesis.
