We studied the changes in proximal embolization of the splenic artery to the intraparenchymal blood flow with Doppler ultrasound. Seventeen trauma patients with spleen injury OIS grade 2-5 underwent embolization of the splenic artery. Peak-systolic velocity (PSV) and end-diastolic velocity (EDV) were measured in intrasplenic arteries initially 1 day after embolization, at early follow-up after 7 days, at intermediate follow-up after 10 weeks, and at late follow-up after 10 months. Resistance index (RI), systolic/diastolic ratio (S/D ratio), acceleration (AC), and acceleration time (AT) were calculated. The results were compared to values from 17 volunteers. RI increased from 0.39 initially to 0.49 (P = 0.002) at intermediate and to 0.52 (P < 0.001) at late follow-up. S/D ratio increased from 1.68 initially to 1.99 (P = 0.002) and to 2.10 (P < 0.001) at intermediate and late follow-up, respectively. Follow-up results of RI and S/D ratio differed significantly from the reference group. AC increased from 1.06 m/s2 initially to 1.89 m/s2 at late follow-up (P = 0.01). AC at late follow-up was not different from reference group (2.33 m/s2). In conclusion, Doppler ultrasound is a useful tool in the evaluation of improvable intraparenchymal blood flow over time after central splenic artery embolization.
