Formula to Predict Platelet Count after Partial Splenic Arterial Embolization in Patients with Hypersplenism

摘要: Purpose To establish a formula to guide appropriate embolization volume for postprocedural platelet gain following partial splenic arterial (PSE) hypersplenism. Materials and Methods The hepatic (Vh) (Vsp) were measured by using 2-mm-thick computed tomography images before after PSE in 20 patients with various chronic liver diseases. A was derived from the relationship between count increase ratio (dPlt%) organ volumes, which then evaluated another cohort. Results After an of median 72.1% spleen (interquartile range, 38.2%–93.8%), dPlt% 67.7% ± 40.0 significantly correlated increasing Vh Vsp ( P = .019, ρ 0.52). Because difference Vh/Vsp (eVsp%; .0003, 0.72), estimated could be eVsp%. actual 0.72). When cohort 14 cases, strict correlation observed Conclusions These data suggest that can predicted procedure anticipated volume. use such prediction prevent too much or little embolization, thereby leading improvement risk/return trade-off PSE.
