Percutaneous Preoperative Portal Vein Embolization Using a Combination of Gelatin Sponge and Histoacryl Glue

Background: Inadequate remnant liver volume is a major cause of postoperative liver failure. Preoperative portal vein embolization (PVE) is used clinically to prevent postoperative liver insufficiency. Purpose: To evaluate the efficacy and safety of preoperative portal vein embolization, by using a combination of gelatin sponge and histoacryl to induce hypertrophy of future liver remnant (FLR) in patients with a hepatobiliary malignancy. Material and Methods: PVE using a combination of gelatin sponge and histoacryl glue was performed in 11 patients (nine men, two women; mean age 60 years, range 46-70 years). These patients were diagnosed with a hepatobiliary malignancy before surgery and their FLR volumes were judged as insufficient to allow for safe resection (FLR
