PURPOSE: To determine the impact of coil embolization of the splenic artery on splenic volume based on computed tomography (CT) imaging. MATERIALS AND METHODS: Splenic artery embolization (SAE) was performed in 148 consecutive patients over an 8-year period in an institutional review board-approved retrospective study. Of these, 60 patients (36 men; mean age, 49 y) had undergone contrast-enhanced CT before and after SAE with a mean time interval of 355 days. Pre- and postembolization splenic volumes were calculated with volume-rendering software. Presence of Howell-Jolly bodies was ascertained on laboratory tests. A trauma control group consisted of 39 patients with splenic laceration and follow-up CT but no splenic intervention. RESULTS: SAE in trauma patients resulted in an insignificant decrease in mean spleen size from 224 cm(3) to 190 cm(3) (P = .222). However, postembolization splenic volume was significantly smaller than follow-up volume in the trauma control group (353 cm(3); P < .001). In nontrauma patients, the mean splenic volume decreased from 474 cm(3) to 399 cm(3) after SAE (P = .068). Multivariable analysis revealed that coil pack location was the only factor significantly affecting resultant splenic volume (P = .016). For trauma and nontrauma patients, distal embolization resulted in significant splenic volume loss (P = .034 and P = .013), whereas proximal embolization did not. No patients had persistent circulating Howell-Jolly bodies after SAE. No patients required repeat embolization or splenectomy. CONCLUSIONS: Coil embolization of the splenic artery resulted in a modest but significant decrease in splenic volume when performed distally; proximal embolization resulted in an insignificant volume change.
