PURPOSEWe aimed to investigate the efficacy and safety of preopera-tive selective intra-arterial embolization (PSIAE) in the surgical treatment of large liver hemangiomas.METHODSData of 22 patients who underwent resection of large liver hemangiomas were retrospectively analyzed. PSIAE was per-formed in cases having a high risk of severe blood loss during surgery (n=11), while it was not applied in cases with a low risk of blood loss (n=11).RESULTSA total of 19 enucleations and six anatomic resections were performed. Operative time, intraoperative bleeding amount, Pringle period, and blood transfusion were comparable be-tween the two groups (P > 0.05, for all). The perioperative serum aspartate transaminase level was not different be-tween groups (P = 1.000). Perioperative total bilirubin levels were significantly increased in the PSIAE group (P = 0.041). Postoperative hospital stay was longer in the PSIAE group. Surgical complications were comparable between groups (P = 0.476).CONCLUSIONPatients who underwent PSIAE due to a high risk of severe blood loss during resection of large liver hemangiomas had comparable operative success as patients with a low risk of blood loss who were operated without PSIAE. Hence, PSIAE can be used for the control of intraoperative blood loss, espe-cially in surgically difficult cases.
